Stres sangat mempengaruhi kekebalan tubuh seseorang, sehingga akan menyebabkannya mudah terserang penyakit.

KOMPAS.com — Sudah banyak diketahui bahwa stres bisa menimbulkan berbagai masalah bagi kesehatan seseorang. "Perlu adamanajemen stres yang baik agar stres tidak berkembang menjadi masalah kesehatan yang serius dan buruk bagitubuh," tukas RustikaThamrin, SPsi, CHt, CI, MTLT, psikolog dari Brawijaya Women and Children Hospital,dalam acara "How to be a Happy and Productive Career Women" di Thamrin Nine, Jakarta, beberapa waktu lalu. Akibat stres tidak hanya tampak kondisi wajah yang murung atau lekas tersinggung dan marah. Ada beberapa akibat lain yang tanpa Anda sadari bisa mengganggu aktivitas Anda sehari-hari:
1. Emosi negatif. Hal yang paling mudah terlihat ketika Anda mengalami stres adalah adanya emosi negatif yang tidak stabil sehingga menyebabkan seseorang menjadi mudah marah karenaemosi yang tidak terkontrol.
2. Perilaku buruk. "Stres bisa memicu perbuatan buruk seseorang, misalnya mengonsumsi narkoba, atau bunuh diri. Hal ini sebagai bentuk penyimpangan karena dia tidak mendapatkan kesenangan dalam hidupnya sehingga dia mencari pelampiasan dengan melakukan perbuatan buruk," tambahnya.
3. Konsentrasi terganggu. Stres sangat memengaruhipikiran Anda, termasuk dalam berfokus pada sesuatu hal. Jangankan mengerjakan beberapa hal sekaligus, melakukan satu hal saja kadang-kadang membutuhkan waktulama. Kalau sudah begini, Anda akan sulit menyelesaikan pekerjaan dengan tuntas.
4. Gangguan makan. Pada beberapa orang,stres bisa membuat seseorang kehilanganselera makan, atau sebaliknya, membuatkeinginan makan menjadi bertambah berkali-kali lipat. Jelasgangguan makan ini akan berakibat burukbagi pengidapnya. Tak ada yang ingin menjadi obesitas gara-gara stres, kan?
5. Hiperaktif. Hiperaktif di dalam otak menyebabkan orang tidak dapat berpikir secara normal. Mereka bisa membuat keputusan tanpa dipikirkan lebih dulu, salah menilai orang lain, memori pun terganggu. Pada akhirnya, kondisi ini akan menyebabkan timbulnya masalah bagi dirinya sendiri.
6. Mudah sakit . Stres sangat memengaruhikekebalan tubuh seseorang sehingga akan menyebabkannya mudah terserang penyakit. Salah satu penyakit yang sering menyerang tubuh ketika stres adalah migrain dan juga maag. "Sekitar 80 persen orang mengalami masalah kesehatan karena disebabkan oleh gangguan fungsional dalam tubuh akibat stres sehingga hormonnya terganggu. Sedangkan 20 persennya adalah benar-benar karena alasan kesehatan yang menurun atau luka," jelas Rustika.
7. Insomnia. Stres bisa mengganggu otak dan memberi beban berat sehinggamemengaruhi waktu tidur dan juga kualitas tidur. Jangan lupa, insomnia bukanmasalah berapa jam Anda tidur, melainkan lelap-tidaknya Anda tidur. Meskipun Anda menghabiskan tujuh jam di atas tempat tidur, misalnya, tetapi jika Anda tak dapat mengistirahatkan pikiran, itulah saat Anda mengalami insomnia.
Barmac of vsi rotor
Barmac or VSI Rotor
Hello Everyone.
I have a Barmac 3000 VSI equipment.
Some time ago i stoped using it for market reasons and now i want to start using it back but realized that someone had stolen the rotorof it.
I have been searching the web but found none spare rotors. Does someone has a spare rotor that could sell me? Or maybe the design plans so that i can build one?
Many thanks to all for your help

Hardfacing table liners of vertical Roller mill
Hardfacing Table Liners of Vertical Roller Mills
hardfacing of table liners of a vertical roller mill
hi friends,
I have a problem regarding the hardfacing of roll table liners and wear segments of MPS vertical roller mills. The mill is being used for grinding of limestone mainly at a rate of 215 tonnes per hour. I would be thankful if anyone can tell me which type (composition) of hardfacing to use to reduce the wear rate. It will be of great help if the information regarding the company that does the hardfacing or the composition and process of hardfacing can be elaborated.
Also I would be thankful if any one can suggest me the new ways of maintenance of Vertical roller mills.
thanks in advance

Do not forget you are crushing one material againstthe other and wear will always occur.
Perhaps you should look at your tertiary crushing/grinding circuit and think about a cetrifugual crusher such as Spokane crusher for example. They usethem in asphault sand serviceand secondary crushing as well in mobile and stationary applications.

Hard facing of Vertical Rollers
The liners can be hard faced one by workhardening types of electrodes where the hardness go on increasing while it is in working condition.The layers should not be in one lines.It should be criss crossed. Perhaps we can give a better idea of hard facing if you can provide me asketch indicating the actual place where wear is taking place.
Also please tell us whether the liners are sujected to temperature and is so at what temp?

Dear Arun:
I recomend thinking in a Complex Cr Carbide alloy or a TiC carbide applied by Open Arc process. Electrodes for this application only if is for minor repairs.
Some companies also have segments ( generally in Ni-Hard ) that could be applied to the table. Less timeto apply but the wear resistance is not so good.
Contact me (eutecsol@iol.pt) if needed some alloys and procedures. Its better if you got a drawing with the dimensions.

rip protection
Dear Mr. Narayanan Nalinakshan,
rip protection is based on rip detection --> if done by vulcanized-in detection loops --> these are an integral part of belt manufacturing --> so please contact renowned beltsupplier and asking for their rip-detection proposals one may also ask for all further technical equipment to protect your belts.

Rip protection and Rip detection.
Thank you Sir,
In between,failure of a deflector plate mounted inside the discharge chute of reclaimer ripped about 400 mtrs of steel cord belt.
For new installations we can think of going for belts with rip protection.In case of existing belt,both EP &Steel cord it becomes a difficult affair.Removal of all causes and detection of rip in time tominimise the damage is required.
We propose to install lifting magnet to remove scraps at strategical points and also fixing some device near the discharge chute
for early detection of rip.I really want to know if some one can suggest any other successful/better methods.
Rgds,

Belt Rip Protection Using Modern Chute Designs
Further to my last comment, I am not aware of any belt rip that has occurred with one of our curved hood and spoon designs. We can mimic your tramp metal material mixed in the flow stream and classify the rip damage mechanism with the existing chute and then demonstrate a new chute will not allow thetramp metal to apply the necessary ripping force with our DEM code ROCKY. See our website for some flow images of rocks in chutes: http://www.conveyor-dynamics.com/rocky.htm Look at the examples and demos.
Use your imagination of tramp metal that can be added to this rocky flow stream. Since we can record all impact and shear reactionsof the particle set, I claim we can show how a new chute design will virtually eliminate all future rips.

rip protection is based on rip detection --> if done by vulcanized-in detection loops --> these are an integral part of belt manufacturing --> so please contact renowned beltsupplier and asking for their rip-detection proposals one may also ask for all further technical equipment to protect your belts.

Rip protection and Rip detection.
Thank you Sir,
In between,failure of a deflector plate mounted inside the discharge chute of reclaimer ripped about 400 mtrs of steel cord belt.
For new installations we can think of going for belts with rip protection.In case of existing belt,both EP &Steel cord it becomes a difficult affair.Removal of all causes and detection of rip in time tominimise the damage is required.
We propose to install lifting magnet to remove scraps at strategical points and also fixing some device near the discharge chute
for early detection of rip.I really want to know if some one can suggest any other successful/better methods.
Rgds,

Belt Rip Protection Using Modern Chute Designs
Further to my last comment, I am not aware of any belt rip that has occurred with one of our curved hood and spoon designs. We can mimic your tramp metal material mixed in the flow stream and classify the rip damage mechanism with the existing chute and then demonstrate a new chute will not allow thetramp metal to apply the necessary ripping force with our DEM code ROCKY. See our website for some flow images of rocks in chutes: http://www.conveyor-dynamics.com/rocky.htm Look at the examples and demos.
Use your imagination of tramp metal that can be added to this rocky flow stream. Since we can record all impact and shear reactionsof the particle set, I claim we can show how a new chute design will virtually eliminate all future rips.

Dulu, ada seorang guru SMA saya, sayang saya lupa namanya, berkata bahwa guru itu ada di mana-mana. Kalau kita mau membuka mata sedikit lebih lebar, kita dengan mudah menjumpai mereka. Mereka itulah ‘guru-guru kehidupan’, begitu katanya. Waktu itu saya menanggapi dengan mata setengah mengantuk dan komentar dalam hati “Ah, klise…!”. Hingga beberapa minggu lalu saya menemukan makna perkataan beliau dalam kejadian sebenarnya.
Di rumah saya ada bibik yangsuka membantu mebereskan pekerjaan di rumah, kami memanggilnya Mpok Iyok. Ia sudah ikut bersama saya selama hampir 15 tahun, semenjak saya masih kuliah. Bersama beberapa teman kami mengontrak rumah dan di situlah saya pertama kali mengenalnya. Menurut saya ia wanita yang kuat, fisik dan mentalnya, lugu, dan sederhana.
Singkatnya, pada suatu hari saya mendapati ia tengah sibuk menanam beberapa tangkai bunga hias yang dibawa istri saya dari pesta pernikahan kerabat kami beberapa hari lalu. Bunga dan daunnya tampak sudah melayu, tapi Mpok dengan semangat menampung tanah dalam pot plastik lalu menanam tangkai-tangkai bunga itu. Melihat itu saya berujar kepadanya, “ Pok , bunga itu nggak bakal numbuh kembang lagi!”. Saya menjelaskan bahwa bunga itu hanya akan berkembang sekali saja. Ia hanya tersenyum dan menjawab, “ Nggak pa-pa. Numbuh aja udah seneng saya.”
Hari-hari selanjutnya saya melihat Mpok selalu menyempatkan diri menyiram kembang itu. Tanpa pupuk. Cuma air keran. Saya hanya menggeleng-geleng sambil tersenyum melihatnya. Kadang disertai olok-olok bahwa biar ditimbun pupuk satu truk juga tidak bakal muncul bunganya!
Beberapa bulan berlalu.
Saya pulang ke rumah dengan badan penat luar biasa. Saat meniti tangga masuk, saya menoleh dan tertegun melihat sesuatu. Pohon kesayangan Mpok Iyokberbunga! Dan bukan cuma satu tetapi 4 kuntum! Sementara di beberapa tangkai lain masih ada kuntum-kuntum yang siap mekar. Ternyata kesabaran Mpok Iyok selama ini berbuah juga. Saat itu saya teringat lagi perkataan guru SMA saya dan tersenyum menyadari bahwa Mpok Iyok telah menjadi salah satu ‘guru hidup’ saya …

MANCHESTER, KOMPAS.com - Bek Manchester City Vincent Kompany mengatakan timnya sejak awal musim ini menargetkan meraih gelar juara Premier League dan dengan begitu telah menyiapkan diri menghadapi kesulitan,
City sempat menguasai klasemen dengan rekor tak pernah kalah. Namun,mereka perlahan kehilangan konsistensi sehingga kini berada dalam bahaya kehilangan singgasana.
Dalam enam laga terakhir, mereka menelan dua kekalahan dan satu hasil imbang. Denganhasil itu, mereka menguasai klasemen dengan 54 poin. Mereka hanya unggul selisih gol dari Manchester United di tempat kedua dan lima angka dari Tottenham Hotspur di peringkat ketiga.
Akhir pekan ini, City akan menghadapi Fulham, di Etihad Stadium. Menurut Kompany, situasi klasemen tak akan memengaruhi performa City.
"Jika ada satu hal yang aku tahu tentang tim kami, ituadalah bahwa kami kuat secara mental. Kami telah mengalami tekanan seperti ini selama 3,5 tahun dan ini tak memengaruhi kami,"

Anda pengen bayi tumbuh cerdas
Ingin Bayi Anda Tumbuh Cerdas, Konsumsilah Ikan
REPUBLIKA.CO.ID, JAKARTA - Ibu hamil yang banyak makan ikan memiliki kemungkinan lebih besar memiliki anak cerdas dan pandai bergaul. Suatu penelitian yang dibiayai Uni Eropa mengemukakan ibu hamil yang banyak makan tuna, sarden dan salmon akan melahirkan bayi yang punya kemampuan bagus dalam berbagai tes keterampilan dan kecerdasan.
Para peneliti Spanyol memeriksa dua ribu perempuan pada kehamilan pekan ke-20 dan setelah mereka melahirkan. Para ibu itu ditanyai soal makanan dan mereka menjalani tes darah untuk mengetahui tingkat omega-3 dan omega-6.
Bayi mereka dites kecerdasan verbal dan keterampilan motorik serta kemampuan bersosialisasi. Ternyata, ibu yang mengkonsumsi ikan-ikan tersebut saat hamil, punya anak yang nilai tesnya tinggi.
Para peneliti dari University of Granada menyimpulkan bahwa Omega-3 membantu perkembangan otak dan mata janin. Hasil penelitian yang dimuat American Journal of Clinical Nutrition juga mengemukakan Omega-3 mengandung DHA yang merupakan komponen utama sel otak dan membran.
"Jumlah DHA yang dikirimkan ke janin lewat plasenta mungkin merupakan hal sangat penting dalam perkembangan janin,"ungkap penelitian tersebut.
Namun, penelitian itu juga menyimpulkan bahwa terlalu banyak makan ikan-ikan tersebut juga dapat memberi dampak buruk pada perkembangan bayi. Menurut para ahli, sangat penting bagi calon ibu untuk menyeimbangkan makanan jika mereka ingin memperbanyak asupan Omega-3.

Your first point of contact should be you steel producers.They are the best source of such information.
Low temperatures can do strange things to mechanical properties. Not only will steel become more brittle, but you can see odd things happeningto UTS and yield points.
In many cases, the steel producers will not give you a yield point, but a 0.2% proof stress (sometimes just called proof stress). This is because there is no significant yield point at these low temperatures. The 0.2% proofstress is the stress at which you will see a permanent 0.2% strain in the test samplewhen the load is removed. What this means is that you need to be careful when selecting the design limit state as there is no effective yield in the material. With such materials, the 0.2% proof stress is substituted for the yield stress, however you cannot use the limit state that you would normally use for material that had a yield point and so a point of plasticity.
Many years ago, I was ProductDevelopment Engineer with Dexion Australia. Our pallet racking was used in freezers, and in the main, we did not have to do anything as far as load capacity was concerned. One thing we did have to do was to halve the allowable beam deflection as with the standard deflection limit, the two part interlocking C section beams would open upand then when the load was removed, the beam sections would not return to their normal positions. Even when removed from the freezers and allowed to get to room temperature, they would not return to their normal positions.

Maximum belt speed
Maximum Belt Speed
Dear Mr./Mrs.
I’m looking for a coorelation between different parameters in belt conveyor design to find maximum belt speed. I’ve just found something like that in CEMA ver.6 (Eq. 3.7 & 3.8) for spillage and slip-back, but it’s clear that these equations are wrong. Could you help me to know if there are some equations to solve my problem?
I’m designing material handling system of a steel making plant that the main belt conveyor transfers DRI, Lime, Coke, and Additives in the rate of 720t/h.

The speed is highly dependent on your design criteria. Dust control, spillage control, belt tracking, et al.
Your tonnage is very light. Speed should not be the limiting factor. Once the conveyor width falls below 700 mm, there are dimishing returns to go faster. In addition, the conveyor length and geometry needs to be understood.
To control dust, noise, spillage, and belt capacity the densities, particle sizes, feed and receiving conveyor together with their chute geometries need to be given. Chute geometry design goes with the belt width selection and belt speed.
Thus, there are many details that govern the selections.

Belt with criteria small conveyor
Belt Width Criteria for Small Conveyors
Belt width fixing criteria for small conveyors used to feed other conveyors
Quite often we use small conveyors (Approx 10/12 metre length) within building to distribute the material on to the other conveyors both in unidirectional mode or in reversible mode to reduce transfer height. Many a times such conveyors are called beltfeeders, which may not be exact term since the rate is basically set by the preceeding conveyor. Quite often such conveyors or belt feeders are made wider with less speed. We are little confused as to whether such short belts need to be wider than normal with less belt speed or not. Moreover such belts are many times fully skirted to avoid spillage. Now with such belts is it necessaryto consider material shear as in case of hopper. Consideration of shear can make the conveyor very power consuming, although actual case may not be so. It is also noted that in ISO no such method is given to calculate crosssectional area of fully skirted belt. There is another issue that materaial may not be fully spread out in a wider belt from a narrow chute, dictaed by the feeding conveyor, unless some spreading arrangement is provided.
Hence the bottom line is that is it at all benifitial to increase the belt width with reduced speed and consider material shear in power calculation and in the process losing from both sides ?

Temukan Kembar Indonesia Setelah Berpisah 30 Tahun
Antara -
London (ANTARA) - Membayangkan bila anda memiliki saudara kembar yang hilang dan tidak pernah berjumpa biasanya ada dalam kisah dongeng, tetapi tidak untuk dua wanita Indonesia yang kini menetap di Swedia.
Kisah kedua perempuan kembar Indonesia yang diadopsi secara terpisah oleh pasangan Swedia hampir 29 tahun lalu, dan sekarang menemukan satu sama lain setelah hidup hanya 25 mil terpisah di selatan Sweden dimuat harian Inggris The Telegraph, Rabu.
Kisah bertemunya kedua wanita kembar Indonesia itu, Emilie Falk dan Lin Backman disampaikan kantor berita AFP. Menurut hasil tes DNA yang dilakukan dua bulan setelah penyatuan pada Januari tahun lalu, dinyatakan 99,98 persen mereka bersaudara.
Disebutkan keduanya diadopsi dari sebuah panti asuhan di Semarang di utara Indonesia oleh pasangan Swedia, namun tidak disebutkan dalam salah satu dari dokumen mereka bahwa mereka punya saudara kembar.
Tapi komentar dari sopir taksi yang dibuat untuk orang tua Backman tentang `kakaknya` mendorong mereka untuk membuat catatan dari nama bahasa Indonesia anak-anak.
Kembali di Swedia, Backmans ditemukan dan melakukan kontak dengan Falks, dan meskipun mereka bertemu beberapa kali ketika masih anak-anak.
Fakta bahwa mereka adalah non-identik, dan perbedaan banyak di surat adopsi seperti nama ayah yang berbeda, membuat mereka percaya bahwa mereka tidak mempunyai hubungan. Pada saat itu tidak ada tes DNA dan akhirnya keluarga kehilangan kontak.
Namun ketika Emilie Falk menikah dua tahun lalu dia mulai berpikir tentang keluarganya dan adopsi."Ketika saya bertanya kepada ibuku dia menceritakan kisah ini lagi, dan saya memutuskan untuk mencari Lin,"kata Falk.
Dengan nama kecil gadis yang diadopsi melalui jaringan untuk anak-anak Indonesia yang diadopsi oleh keluarga Swedia, ia akhirnya menemukan Backman melalui Facebook.
Dia mengirimkan pesan dan termasuk hari ulang tahunnya dan nama ibu kandung. Backman menulis kembali mengatakan:"Wow, itu nama ibu saya juga dan itulah hari ulang tahunku."
"Saya lahir pada tanggal 18 Maret 1983 di Semarang dan nama ibu kandung saya adalah Maryati Rajiman,"kata Falk dia menulis, dan cepat menerima jawaban:"Wow, itu nama ibu saya dan itulah hari ulang tahunku!"Mereka menemukan bahwa mereka memiliki banyak kesamaan.
Dari hasil tes DNA mengukuhkan bahwa ada kemungkinan 99,98 persen keduanya bersaudara.
Seperti yang sering diceritakan dalam kisah-kisah kembar yang telah terpisah, si kembar menemukan banyak kebetulan dalam hidup mereka.
Mereka tinggal hanya 40 kilometer terpisah di bagian paling selatan Swedia, mereka berdua guru, mereka menikah pada hari yang sama hanya satu tahun terpisah dan bahkan berdansa dengan lagu pernikahan yang sama:""You and Me"oleh Lifehouse.
"Ini benar-benar aneh,"kata Falk.
"Ketika Lin menelepon saya (dengan hasil tes DNA), saya ingat saya sedang duduk di mobil dan ketika dia mengatakan bahwa saya mulai tertawa, karena merasa sangat aneh,"katanya, menambahkan:"Saya tiba-tiba mulai berpikir bahwa kita berbagi rahim. Itu benar-benar aneh, tapi benar-benar keren juga."
Sejak itu kedua telah terus berhubungan dekat, dan telah berbicara tentang pergi ke Indonesia untuk mencari orang tua biologis mereka.
Ada sejumlah rincian, kontradiktif beberapa, di koran adopsi, termasuk referensi untuk ayah mereka sebagai sopir taksi.
"Kami sangat ingin tahu apakah dia adalah sopir taksi,"kata Falk.
Ditanya apakah ia berharap menemukan tentang kembarnya sebelumnya, Falk menegaskan"tidak ada gunanya menjadi sedih tentang sesuatu dan saya hanya senang telah menemukan dia."
Kedua perempuan sekarang tetap berhubungan dekat dan sedang mempertimbangkan perjalanan kembali ke Indonesia untuk mencari orang tua biologis mereka.

Sejak itu kedua telah terus berhubungan dekat, dan telah berbicara tentang pergi ke Indonesia untuk mencari orang tua biologis mereka.
Ada sejumlah rincian, kontradiktif beberapa, di koran adopsi, termasuk referensi untuk ayah mereka sebagai sopir taksi.
"Kami sangat ingin tahu apakah dia adalah sopir taksi,"kata Falk.
Ditanya apakah ia berharap menemukan tentang kembarnya sebelumnya, Falk menegaskan"tidak ada gunanya menjadi sedih tentang sesuatu dan saya hanya senang telah menemukan dia."
Kedua perempuan sekarang tetap berhubungan dekat dan sedang mempertimbangkan perjalanan kembali ke Indonesia untuk mencari orang tua biologis mereka.
Salina vortex
Salina Vortex Corporation
Salina Vortex supplies material handling valves to a global network of Original Equipment Manufacturers, Fortune 500 companies, and process engineering firms. Throughout the world, you can find Vortex Valves handling the world’s dry bulk solids. It took the company three short decades to reach the level of success it enjoys today. The company originated from humble beginnings in the late 70s.
Neil Peterson , a mechanical engineer experienced in pneumatic conveying, and Lee Young, Neil’s son-in-law, started Salina Vortex in an early Cold War era military building in 1977. Salina Vortexwas named after Salina, Kansas (the city of which the company was founded) and ‘Vortex” after Neil’s initial valve concept that created a vortex to direct material flow.His purpose and dream was to design and manufacture innovative and problem-solving valves for handling drymaterials in pneumatic conveying systems.
Neil knew that traditional butterfly valves and knife gates were suitable for handling gases and liquids, however they had deficiencies in handling dry solids. A new design was needed to eliminate the problems associated with these types of valves, specifically material flow obstruction, self - cleaning, and seal abrasion. His perseverance paid off with a valve design he deemed the Orifice Gate.
In 1980, the company was awarded a patent on the Orifice Gate. This new valve design surpassed the industry’s expectations for handling dry materials in pneumatic conveying. Chemical Processing Magazine awarded the OrificeGate its “Vaaler Award”--judging it a major contributortoward more efficient and effective operation of plants in the chemical processing industry. This achievement changed the way process engineers selected valves for handling dry solids.
Between 1980 and 1989 additional products were developed. The unique Wye Line Diverter, which applied the same design concepts of the Orifice Gate, dramatically improved process efficiencieswhen compared to traditionalflapper or tunnel style diverters. The Salina Roller Gate and Clear Action Gate were also conceived during this decade. Each new product added more dimension to the material handling capabilities of the Vortex line of gates and valves. To address increasing demand of these new productlines,
additions were made in 1987 and 1989 to the original building. In 1989, Lee Young became CEO of the company in preparation for Neil’s retirement.
Under Lee’s direction Vortex continued to increase its market presence and expand its manufacturing facilities throughout the 1990’s. The company received many industry accolades for new product development and achievement. These awards include: two Innovation in Powder / Bulk Technology Awards (the only repeat winner for this award), Kansas Society of ProfessionalEngineer’s Governor’s New Product Award, Kansas Department of Commerce’s Breakthrough Product of the Year Award, and Kansas Exporter of the
Year Award. In 1999, Lee earned Ernst and Young’s Entrepreneur of the Year Award.
Since 2000, Vortex has continued to increase its market share and develop new products. Additional Industry recognition followed throughout the world:
• Vaaler Award for the Seal Tite Gravity Diverter
• Processing Magazine’s Breakthrough Product of the Year
• American Institute of Chemical Engineer’s Best in Show Award for the 2001 International Powder Show,
• Powder and Bulk Engineering’s Reader’s Choice Award
• Chemical Equipment Magazine’s Reader’s Choice Award.
In addition to these honors, many national and international publications have featured stories and case histories relating to Vortex slide gates and diverter valves.
In June of 2006, Salina Vortex expanded once more by moving into a state-of-the-art manufacturing facility andoffice complex that spans over a 15-arce campus. This new facility will allow enough space for Vortex to introduce lean manufacturing methods supported by leading-edge fabrication equipment and laser cutting technology, as well as, provide additional offices for its corporate staff. This new complex will be located at 1725 Vortex Avenue in Salina, Kansas.
Vortex’s success comes from a philosophy, which includes willingness to work with special customer needs, focuson quality, and timely customer service.

Republik Indonesia mengharapkan TNI AL sebagai kekuatan
TNI AL Jayapura Tingkatkan Patroli di Perairan
REPUBLIKA.CO.ID, BIAK -- TNI Angkatan Laut di Jayapura diminta meningkatkan pengamanan di wilayah perairan laut setempat. Peningkatan pengamanan tersebut diminta, karena tindakan pengambilan ikan ilegal, pembalakan liar, masuknya pendatang secara ilegal, dan penyelundupan seringkali terjadi di daerah tersebut.
Komandan Pangkalan TNI ALJayapura, Laskma TNI FX Agus Susilo meminta jajaranprajurit di Pangkalan TNI AL (Lanal) Biak untuk peningkatan patroli itu."Permasalahan yang masih timbul di perairan Papua termasuk Pangkalan TNI AL Biak menyangkut illegal fishing , illegal logging, illegalentry , illegal oil , serta penyelundupan," ungkap Komandan Lantamal Jayapura ini di Biak, Jumat (3/2).
Laksma Agus mengharapkan, komandan Lanal Biak yang baru dapat lebih meningkatkan pengawasan, pengendalian serta patroli di perairan Biak sehingga dapat menjamin pencapaian sasaran tugas secara efektifdan efisien. Pengawasan tersebut juga dilakukan untuk penegakan kedaulatan hukum laut serta melakukan koordinasi pengaturan pertahanan pangkalan.
"Lanal juga diminta membantu proses penyelesaian perkara pelanggaran hukum di laut dan menyelenggarakan pembinaan potensi maritimmenjadi kekuatan pertahanan keamanan Negara di laut," harapnya.
