Screw Conveyor Sizing : Things to Know EnSight Solutions

Flow Rate and Screw SizeTrough Loading and SizingLook For Variable Frequency Drives and Operating VoltagesSince 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 the conveyor and the lighter the material, the faster the machine can work. The capacity of a screw conveyor is measured in cubic feet per hour.When calculating screw conveyor sizing, manufacturers lo
