Please assist with a formula for calculating flow rate There are charts available, but we need to know the loading that you desire, the size of the screw conveyor, the pitch of the screw conveyor Then the charts will give capacity of cubic feet per hour per rpm You can then use this up to a "maximum economical speed"Screw Conveyor Sizing Flow Rate and Screw Size Since the purpose of a screw conveyor is to move product from point A to point B, you’ll want to determine how fast you want the product to move (this is called the flow rate or capacity) Of course, a screw conveyor can only hold so much material at one time, but the bigger the screw inside Screw Conveyor Sizing : Things to Know EnSight Solutions
Screw conveyors can transport grain in either a horizontal, vertical, or inclined position Screw conveyors become less efficient when they are used to convey material vertically For conveyors at an inclination of 15 degrees the capacity decreases by about 30%, at an inclination of 25 degrees the capacity decreases by over 55%The driving power of the loaded screw conveyor is given by: P = PH + PN + Pst Where, P H = Power necessary for the progress of the material P N = Driving power of the screw conveyor at no load Pst = Power requirement for the inclination of the conveyor Power necessary for the progress of the material PH: / Screw Conveyor power calculationScrew Conveyor Power Calculation Screw Conveyor Capacity
