We screen lime stone kankar material to seperate clay from limestone.lime kankar has upto 12% moisture and is sticky in nature.Steel wire meshes in these screens get frequently coated with clay and are creating problems in screening. How can we avoid this coating?

As of now we are using spring steel wire meshes. 25mm opening. deck size is 1650x6500mm size. linear motion screen. we also tried using SS plate mesh, which did not work out. Is there any automated system available to clean the screen decks?

The best application for this situation is to use a "D" wire in a stainless steel wire with urethane cross bars. What this does is act like a trampoline, and the wires vibrate seperately from one another, keeping constant motion on the cloth. Clay is a nasty situation to deal with, but we have found with our customers that this is the best application.

Please contact me at 888-464-9473 if you would like more information.

Use Stainless Steel

Posted on 2. Apr. 2010 - 10:47

Hello: I see Julie has recommended the use of stainless steel wirecloth. THAT is an excellent response and correct in my opinion.

WHY???

most people buy AR steel, piano wire, high tensile wire or similar ....and that is ok UNLESS you have a problem.

1. STAINLESS STEEL T304, 317L ......brings this to the party. If you look at A/R carbon steel alloy wire under a magnifying glass......you would see the following....after minimal use......the WIRE...under magnification......YOU would see "pitting" or roughness due to RUST and or wear....or abuse. when wire "pits" you would see that material........will start to slow down and "ADHERE" or stick to the wire diameter. THEN after a time, the OPENING would eventually close UP....and or PLUG or completely close...."Oops no opening......equals no screening"

when you pay the expense of STAINLESS STEEL...which people generally BALK at...stainless under MAGNIFICATION....you will NOT SEE "pitting" ....hence no sticky material STICKING TO THE WIRE.....no plugging......and viola........no PLUGGING............equals open wirecloth equals MORE EFFICIENCY.....equals more cost effective operation..........equals a "Happy Boss"

Last but, certainly not least......."You must make darn sure........that you and your mtce folks.........KEEP THE WIRECLOTH TENSIONED TIGHTLY.....it must be very tight......or what we call "DRUM HEAD TIGHT" or the screens will PLUG.

After you install wirecloth........you MUST go back after one shift......MUST. AND take an extra TURN on each tension bolt........because...under vibration...the nature of WOVEN WIRECLOTH....is to SLACKEN off.....a bit....LOOSEN UP A bit.....and YOU must retighten...to maintain. TENSION, AND screen efficiency.

THIS is a SUPERB RULE to teach your employees........ LOOSE equals wirecloth breaks!!!!

Dry Screening Sticky Material - Solved

Posted on 28. Jun. 2010 - 01:03

My name is Tommy we have developed the most aggressive screening plant in the world using Flip Flow technology.

There is no material this can't handle there is similar types of machine out there but none as aggressive, as each "deck" is independently driven.

We have had a lot of success with every material we have tried so far even replacing

wash plants in some instances.

If you need to see proof see the website crsni.com I would be thrilled to get any feed back I can from any of you, Thanks

Ball Tray Deck

Posted on 29. Jun. 2010 - 04:49

Install a ball tray deck if possible under that tough screening opening......and POSITIVELY ACTIVATE thee wires........to keep clean.......use in conjunction with a MAJOR WIRE FLEXMAT STAINLESS steel self cleaning wirecloth and hopefully a nice strong high G factor stroke on the vibrating screen shaft............

and bingo no plugging......

GOOD LUCK GB

we had similar blockage problem since we install the vibrating screen (2007). Then we changed the wire mesh to conveyor belt (we punch to required opening). It works very well till now. The only disadvantage is the efficiency will drop. But can tolerate that and no more clogged screen.

try...

Use a "shaped" wire, such as a "S" or "D" in stainless steel. These style of wires operate independantly of one another so there is constant bounce action for the material. Please view our website www.unifiedscreening.com, or contact me at (888) 464-9473, e-mail: julies@twincitywire.com. Be glad to answer any further questions and/or give you a quote.

It's the make up of five different materials. Copy and paste into a text editor then insert spaces between values until they line up and make sense.
