Screw feeders are used in thousands of material handling applications and designed to meter bulk materials at a controlled feed rate. A standard screw conveyor is normally fed by another conveyor and the amount of material being discharged is directly proportional to the amount being introduced at .
Understanding Conveyor Belt Calculations. Understanding a basic conveyor belt calculation will ensure your conveyor design is accurate and is not putting too many demands on your system. When the head and tail pulley are the same size: L=(D+d)/2 x +2C. When one pulley is larger than the other pulley: L=(D+d)/2 x +2C+(Dd)2/4c.

The first, smaller screw conveyor (referred to as the feed screw) which operated as a variablerate feeder, was used to introduce material to the larger screw (referred to as the screw conveyor). The feed screw passes through a cylindrical feed hopper which is mechanically agitated to promote the uniform introduction of material to the feed screw.
Calculation of the nominal flow can be done once the screw geometry, its rotation speed and the filling coefficient are known. The flow rate of a screw conveyor or feeder depends on a number of interlinked factors: geometry of the screw rotation speed inclination geometry of the feed hopper and tube flowability of the material.
