Fixed roll with "on-off" motor actuator:• In this system the discharge roll is mounted on the frame in a fixed position and a timer controlled pulley moves the cloth at "vacuum off" to allow cake discharge and "vacuum on" during filtration. A special tilting feed box pours the slurry onto the filter deck when the cloth moves at "vacuum off".

The Table Filter - Solid Liquid Separation

Description. The Table Filters belong to the top feed group, introduced in the early 40's and were rather small and of a simple design. Their main limitation was at the discharge zone since the cake was contained in a fixed rim and special sealing arrangements had to be provided in order to avoid the spillage of brine at the table's circumference.
