Slurry and conditioning medium feed device for slurry press

摘要

The feed device has a pair of non-return valves (1) positioned on either side of a central feed connection (7), coupled to hydraulic cylinders (4) operated by a symmetrical pump heads (6) of a feed cylinder (2), associated with respective hydraulic cylinders (3). A central discharge connection (8) is connected to each pump head via further hydraulic cylinders (9). Pref. the operation of the feed device is controlled via a microprocessor for synchronised operation of the hydraulic cylinders (4,3,9) and the non-return valves.
