Screw conveyor size and capacity calculation tool You can find a calculation tool here applying the formula given in this page. Please use only this tool to get a rough idea of a screw size, do not perform detail design with this Excel file.
Screw Conveyor Capacity Engineering Guide 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
The capacity of a screw conveyor depends on the screw diameter, screw pitch, speed of the screw and the loading efficiency of the cross sectional area of the screw. The capacity of a screw conveyor with a continuous screw: Q = V. ρ Q = 60. (π/4).D2.S.n.ψ.ρ.C
K 102 Calculations for screw conveyors Capacity in m2per hour (Q) Q = 47,1 x (D2- d2) s x n xi Capacity in kg per hour (Q) Q = 47,1 x (D2- d2) s n xi sg
Calculation of Conveyor Speed Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.

2018/04/06· Eng. Guide Index Shaftless Conveyor Calculations The following information provides the basic criteria for calculating capacity, horsepower, torsional rating, and deflection. These calculations are critical to the design of a successful shaftless conveyor. Capacity Calculation The specified capacity can easily be calculated by dividing the material capacity given in pounds []
2020/04/27· Conveyor capacity is the maximum amount of material that is transferred by the conveyor in a particular time period. Say, ‘x’ kg in ‘t’ minutes or ‘n’ number of parts in ‘t’ minutes. How to calculate conveyor capacity Suppose the
Screw conveyor design calculation an Engineering 2020-9-7 · Define the capacity required for the screw conveyor. The design of the screw must reach a capacity equal or greater than this value. Example : the requirement for a screw
2014/06/10· In order to calculate the capacity on a screw conveyor, you will need to use an official equation. The equation is as follows: CS =CFH/ CFH at 1RPM.
Keywords: Screw conveyor, conveyor capacity, efficiency 1. INTRODUCTION Screw conveyor is used helix mounted onto a rigid center shaft which is rotated axially in a fixed tube. The screw which is rotating creates aby the
The capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to deter-mine the maximum capacity the conveyor will be required to handle. This capacity is very often stated in terms of
Conveyor capacity is determined by the belt speed, width and the angle of the belt and can be expressed as Q = ρ A v (1) where Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m 3, lb/ft 3)
2017/02/18· Calculating conveyor speeds that have special types of screws is a bit different. In this case, the required capacity will consider capacity factors for the screw type. The required capacity will be multiplied by these capacity factors
