Screw conveyer also called auger. It is widely used in building industry, chemical industry, environmental protection, medicine, metallurgy, food industry, and so on. U-trough shaft screw conveyer is the most common model been used to transfer drilling cuttings in drilling waste management field. It can be feed or discharged at different section or port, very flexible in use. U-shaped conveyor trough is closed, and the cover can be opened. The cover material can be steel plate or good sealing, or Galvanized steel grating plate for easy observation. Depends on the diameter of the auger impeller, there are 12inch screw conveyer, 14 inch screw conveyer, 16 inch screw conveyer and 18 inch screw conveyer.

Below table is parameters for common model screw conveyer

Suitable maintenance can extend lifetime of screw conveyer and insure a reliable performance.
Recommend maintenance of screw conveyer for drilling cuttings transfer is as below:
1) Check the gearbox, bearings and other rotating parts, and add lubricating oil periodically
2) Check the screw conveyer impeller periodically, if there is serious wearing, repair and re-weld it  
3) Do not use the screw conveyer with overload.
4) If there is abnormal noisy during running, stop the screw conveyer immediately and check the reason.

Applications of drilling cuttings transfer screw conveyer
1) It can be used in level to collect drilling cuttings discharged from solids control mud system, like solids control shale shaker, desander, desilter, mud cleaner. And then another set screw conveyer used to transfer the cuttings to next process equipment.
2) Feeding for vertical cuttings dryer, and then transfer the solid waste discharged from vertical cuttings dryer

3) Transfer drilling cuttings or materials from one place to another
