How does a rotary drum filter work? A rotary vacuum filter consists of a large rotating drum covered by a cloth. As the drum rotates into and out of the trough, the slurry is sucked on the surface of the cloth and rotated out of the liquid/solids suspension as a cake. When the cake is rotating out, it is dewatered in the drying zone.
