Rotary Sieve

A rotary screen or sieve allows the screening of powder products by pushing the particles through the sieving mesh, using a screw conveyor or a rotating paddles system.Basically, the machine holds a stack of sieves and then shakes the stack so that the material falls down through all the sieves and gets stuck at each different size opening. The machine was created to get consistent, repeatable results that are more reproducible than hand sieving.
