An inclined screw conveyor is arranged to convey bulk material up an inclined path and is often very desirable as it may solve a conveying problem with a minimum of equipment and occupy a minimum of space A vertical screw conveyor is one that conveys material upward in a vertical path Vertical screw conveyors are sometimes called lifts

1/2 2/3 Pitch For a Inclined Screw Feeder/Conveyor A single incline feeder/conveyor design is an ideal solution when the length of the screw is short enough it does not require a hanger for support When a hanger is required the bulk material flow path is obstructed To go under the hanger the trough loading needs to be under about 30% and
A screw conveyor flow rate also sometimes considered the capacity measures the total mass the conveyor can move per unit of time How to Calculate Screw Conveyor Flow Rate Example Problem The following example outlines the steps and information needed to calculate Screw Conveyor Flow Rate First determine the diameter In this example the

HP = Nameplate Horsepower of the motor on the screw conveyor S = Screw Conveyor Speed The torque rating of the drive shaft coupling shafts coupling bolts and conveyor screw must be greater than Full Motor Torque for proper design A 12 inch diameter screw conveyor was selected for the example The minimum standard shaft size for a 12 inch
Length of the screw conveyor L There is no specific procedure to determine the length of the screw conveyor You can select a suitable length depending on the application Power calculation of the screw conveyor Now we need to calculate the drive power of the screw conveyor This is important to select the motor shaft and bearings
The Screw Conveyor Design Procedure on the following page gives ten step by step instructions for properly designing a screw conveyor These steps plus the many following tables and formulas throughout the engineering section will enable you to design and
PROBLEMS ASSOCIATED WITH INCLINED SCREW CONVEYOR Several things can be done to overcome many of the problems associated with inclined screw conveyor 1 Limit the use of standard screw components to inclines of less than 25⁰ preferably not over 15⁰ 2 Use close clearance between trough and screw 3 Increase the speed over that applicable
Inclined screw conveyors are designed with an incline that allows for an inclination angle of 60 degrees in height and take up less space than horizontal screw conveyors The most common style of inclined screw conveyors is when the feeder is attached or integrated with a hopper silo or silo This design is the most economical when used and
