#### Bearing Load Calculation - Screw Conveyor Engineering Guide - Horsepower Calculation

inWith the Ball Screw a considerable increase (315.40%) can be seen in the stress concentration with respect to the behavior in Figure 9. This represents a safety factor of 2.68 - a 77.1% decrease in the F.S.Many studies on screw conveyors were conducted to examine the performance and to develop new types. The purpose of this paper is to study the effect of percent trough load upon the horizontal screw conveyor power requirement and also gives the idea about selection of conveyor speed and diameter of screw.Level Ground Conveyors. Horsepower required for conveyors transporting material on level ground: 1 hp (English horse power) = 745.7 W = 0.746 kW; 1 ft (foot) = 0.3048 m = 12 in = 0.3333 yd; Lifting Conveyors. With lifting conveyors - add lifting power from the chart below to the level ground power from the chart above.The designed screw conveyor is a horizontal type of screw conveyor. It is used for conveying materials along the same plane. The screws of the screw conveyor are sectional type with a diameter of 130 mm and a pitch of 55 mm between the two screws. The screws are fastened on to a pipe of 48.9 mm diameter. The screws and the pipe together are ...note: calculate the load-bearing belt width b 0 based on the number of per-forations which decrease cross sec-tions. Staggered perforations in partic-ular can reduce the load-bearing belt width considerably. Reduce the figure for the load-bearing belt width b 0 by a further 20 % to take tolerances for per-forations and fabric into account. F U ...This app build to calculate Screw Conveyor Capacity,
