5 CONVEYOR PULLEY SELECTION GUIDE Pulley/Core Diameter – The outside diameter of the cylindrical body of a conveyor pulley, without coating. Finish Diameter – The outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). Face Width – The length of a pulley's cylindrical body.This area is intended to act as the contact surface for the conveyor belt.

shaft and screw assembly known as screw conveyor receives power via the reduction gear box and runs in a journal bearing. The screw on the conveyor is 77 mm apart on the shaft and tapered from 12.5 mm at the feed entry point to 10.5 mm at the discharge end. The screw conveyor and housing provide the shear and compressive forces needed to crush the

A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and ...
