Screw conveyor is suitable for transporting all kinds of powdery granular materials or smaller materials.Such as coal,gravel,lump  coal and sand,cement,cereal,etc,but  not suitable for conveying easy-deteriorated, sticky,and easy-forming  materials.Therefore,it is always used  in cement plant,fertilizer  plant,chemical plant,steel  plant,sugar refinery,paper mill,fiber  nylon factory,feed mill,water  conservancy project,etc.

When the screw shaft rotates, the material moves forward along the trough bottom of the conveyor under the push of the screw blade. The reason why the material does not rotate with the blade is that it is subject to its weight and the friction resistance generated by the trough wall. Therefore, the transport of materials in the conveyor is completely a slip movement. In order to make the screw shaft in a more favorable tension state, we usually place the drive device and the discharge port at the same end of the conveyor, and the feed port at another end. Besides, the spiral shaft is equipped with a thrust bearing at the end of the material movement direction, and when the machine body is long, we will add a hanger bearing on the equipment.

Product Structure：The screw conveyor is mainly composed of head bearing, end bearing, hanger bearing, feeding port, discharge port, screw, trough, trough cover, drive device, etc.
