Screw Works When the screw shaft is rotated, due to the gravity and the friction with the wall of the tank arising from the material, the material can move forward along the conveyor in the bottom of the blade push, which seems not to rotate the nut case along the translational motion of rotation of the screw for the same. Bearing material in the middle of migration, it is relying on the forward thrust behind the materials. Therefore, the material in the delivery conveyor, a sliding movement completely. In order to make the screw shaft is pulled in a more favorable state, the driving means are generally placed at the same port and a discharge end of the conveyor, and the feed port as possible on the other side near the rear. Rotating helical blade passage of the material is conveyed, so that the material does not rotate together with the screw conveyor blade force is the material of its own weight and the screw conveyor cabinet friction materials. Depending on the type of blade surface transport of materials have a physical face, belt surface type, surface type and other types of leaves. Screw terminal helical axis in the direction of movement of the material to thrust bearing materials to screw with axial reaction force, the longer the captain, should be added to the intermediate hanger bearings.zzchangli/key-small-concrete-pump-48/
