Perforated Basket Centrifuges - The most common variation utilizes a perforated rotating basket and a filter media.  The feed material flows into the rotating basket and through the filter material under centripetal force.  Solids are retained in in the basket and are removed either manually by removing the filter bag or automatically with a peeler mechanism.  These centrifuges are very economical to separate particles larger than .01mm and can produce very dry cake.  Additional wash cycles can be employed on the cake to remove original liquid media.

The below categories of basket centrifuges are defined by how the cake is removed from the basket  either manually removed from the top or automaticly using a peeler from the bottom.
