Step 1 : define the requirement. Define the capacity required for the screw conveyor. The design of the screw must reach a capacity equal or greater than this value. Example : the requirement for a screw conveying sugar is 3500 kg/h. Step 2 : calculate the capacity of the screw conveyor. Assume a diameter D.

Basic screw feeders, known for their speed and simplicity, use a jaw to hold the screw. Ensure enough space for smooth jaw movement. If space is limited, consider vacuum feeders to bypass interferences. Keep in mind, vacuum feeders sace some speed and simplicity. Also, consider the height of interferences when determining vacuum tube ...
