Sizing a screw conveyor can be very easy, when you know a few of the basics. Of course, there are many screw conveyor applications which add elements to the calculation set that require some experience and expertise but for most traditional applications the process is well defined and resources are available in every screw conveyor
Get PriceScrew Conveyors are performing their assigned tasks in virtually all types of industries and, After size is determined then exact conveyor speed is determined by dividing the required capacity in cubic feet per hour by cubic feet per hour at 1 revolution per minute.
Get Price30.05.2002· I am in the process of setting up a screw conveyor with a diameter of 10inches, trough of 12 inches, 20 feet long, at an inclination of 35 degrees to the horizontal. The screw is required to convey Calcium in powder form with a bulk density of 80 Lb/cft (1000 Kg/cub.M). The screw speed is 20 RPM. I need help in figuring out what is the KW/HP of the motor required to drive the screw conveyor.
