ABSTRACT:
A pressure filter for separating a liquor from mud liquor slurry and for concentrating a filter cake as a heavy slurry discharge comprising a tank having a ring of filter elements supported by a plate which separates the filter tank from a filtrate chamber. The feed enters the tank under pressure through an enlarged feed cylinder tube located in the center of the ring of filter elements. In the backwashing mode of operation the feed rate is maintained or increased to assist in displacing filter cake from the filter elements.
