How does the weighing screw conveyor work? The screw is supported on the drive side in a maintenance-free flexure. The material is fed in symmetrically to this swivel joint; therefore, the impulse forces generated by the material feeding have only a very slight effect on the weigher.
Screw conveyors are typically designed to convey bulk materials at 15, 30 or 45-percent trough loading, depending upon material characteristics of the specific bulk material. As a general rule, trough loading of 45-percent can be used for light, free-flowing and non-abrasive bulk materials.
When screw conveyor works, the screw shaft rotates, and the material moves forward along the trough bottom of the conveyor under the push of the blade. Because of the gravity of the material and the friction between the material and the groove wall, the material does not rotate with the blade of the screw conveyor.
