Recently one batch of Kuwait safety standard screw conveyors are ready for shipment to Kuwait drilling company. The unique features of the screw conveyor are as below:

1. Required steel grating cover plate for safety.
2. Required HSE safety signs.
3. Required full length Safety Grab Wires along the auger for emergency stop;
4. Required water spray system to prevent the screw conveyor from blocking.
5. Required design for preventing collapse on the steel grating cover plate
6. 
   The screw conveyor is a continuous conveying equipment to transfer drilling fluids and drilling cuttings, it can be installed horizontally and inclined, to collect drilling cuttings from primary shale shaker and transfer to high G drying shaker or vertical cuttings dryer, it will also transfer the discharged solids from decanter centrifuge and vertical cuttings dryer.
   The screw conveyor can be made into different length, each section with standard 12ft length, total length as 2 sections 24 ft, 3 sections 36ft, 4 sections 48ft. the rotating screw diameter with 10 inch, 12 inch, 14 inch, 16 inch, 18 inch. The sections are connected by hanging bearing and shaft assembly.
   The screw flights are spray with wear resistant coating to prolong its service life. The reinforced frame outside the screw conveyor provides high strength to the complete conveyor, and the bearing is world famous brand NSK or FAG for longer working life. The shell cover plate is installed with rubber sealing gasket, which can prevent dust leakage during operation.
   We can provide fixed speed screw conveyor or variable speed screw conveyor, we can also provide CNEX, ATEX or IEC EX explosion proof standard.
   Except for screw conveyor, GN also provide sludge vacuum pump for drilling waste and other slurry transfer, if you need a drilling cuttings transfer system solution, pls contact with GN solids control.

Recently one unit of GN stack vibrating screen are used for Iron core separation and treatment.
GN stack vibrating screen is suitable for wet screening, classification and dehydration treatment of fine grained materials in mineral processing, coal preparation.

This unit with 2 layers screening, 2 vibration motor (normally from US Martin or Italy Oil brand ) drived the vibrating screen as linear motion. The features of the stack vibrating screen is high screening screen, energy saving, low energy consumption, large processing capacity, simple structure for simple operation, stable and reliable operation, small footprint, low maintenance cost. It installed polyurethane material screen, which is abrasion resistance and longer working life,and it is not easily blocked due to the good elasticity. The shaker deck surface treatment by sandblasting process, heavy anti corrosion paint for good anti corrosion performance.
The main structures of stack vibration screen including vibration motor, polyurethane screen, support frame, rack assembly, receiving chute, screen box, feed box, water spray system.
The total screen deck layer is 2, and total screening area is 4.2m2, total power is 2 x 1.84KW, vibration frequency is 25HZ, screen inclination angle is 17.5 degree, the mesh size opening is 0.045mm to 2mm, each screen dimension is 700x1250mm, each shaker with 6pcs screens. The dry ore discharge capacity is 5 ~12m3/h. Except for 2 layers screen deck, we can also produce 3 layers screen deck, 4 layers screen deck, 5 layers screen deck.

Except for stack vibrating screen, GN separation also provide high frequency vibrating screen, dewatering vibrating screen, classification vibrating screen, large linear vibrating screen, large Banana vibrating screen, large flip flow vibrating screen. The polyurethane screens are also produced by GN solids control, for better delivery time and adaptability. If you need a solution for vibrating screen, pls contact with GN separation for more information.
