Centrifuge with cake churning

摘要

A centrifuge includes a conveyor for moving cake along a cake flow path towards a cake discharge opening and further includes a baffle mounted to the conveyor and disposed along the cake flow path. The baffle is provided on an upstream side, facing substantially away from the discharge opening with a concave profile or surface. This concave profile or surface serves to direct a portion of the cake which is headed downstream along the cake flow path, into a recirculation or churning path directed partly back towards a pool. The recirculation or churning of the particulate material facilitates an enhanced washing thereof and improves the removal of solutes or undesirable impurities from the cake.
