2 · Gather the proper belt load calculation to prevent applying too much pressure to your conveyor belt system. When the load is per square foot: P = G1 x C (in feet) x W (in feet) When the load is pounds per hour: P = G2 / (S x 60) x C (in feet) Horsepower Level conveyors: HP = F x S x (P + M) / 33,000
· The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are running at 30%-45% trough fill level.
