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.

CLASSIFY YOUR MATERIAL Materials are classified in table No. 6 on pages 12, 13 and 14. If your material is not listed, it can be classified by comparing it ... Conveyor, Inches HP RPM HP RPM HP
Auger conveyors, sometimes called screw conveyors, are the most common method of handling grain and feed on farms. The purpose of this fact sheet is to describe various types and uses of augers. Capacities and power requirements are given to aid in planning and selection. Information is also given to aid in selecting motors and V-belt drives.
Many years of experience in the design and practical application of screw conveyors has resulted in the refinement of conveyor design. This design procedure, outlined in the Engineering Section of this catalog, makes it possible to calculate size, speed and required power with a minimum of mathematical calculations.
Since one horsepower HP 33,000 ft-lbsmin, required conveyor drive power may be expressed in HP as follows, Te in lbs x V in fpm33,000 ft-lbsminHP HP After calculating Te, it is important to calculate T2 slip slack side tension required to resist slippage of the belt on the pulley.
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.
Mar 04, 2006 4 The conveyor design one has to first decide the tractive pull or sum of all resistances. The sum of resistances tractive pull. The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor
The number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt. The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from Tables 9 through 12 by the arc of contact correction factor and by the length correction factor.

also available. Most commercially available industrial motors used in screw feeder applications are NEMA Design B motors. Depending on the horsepower and base speed, a NEMA design B motor can generate up to 275-percent of the nameplate rated torque at start up when started at full voltage across the line. Please refer to Figure 1 below.
