Title:
METHOD FOR THE OPERATION OF A FILTER PRESS COMPRISING A PLUNGER
Document Type and Number:
WIPO Patent Application WO/2005/108049
Kind Code:
A1
Abstract:
The invention relates to a method for operating a plunger-type filter press (1). According to said method, the plunger (4) is advanced at a first speed (V1) in a first phase without applying pressure to the material (2) that is to be pressed when the pressing chamber (3) is partially filled while being advanced at a second speed (V2) in a second phase when hitting the material (2) that is to be pressed and applying pressure to the same, the second speed (V2) being substantially lower than the first speed (V1). The inventive operating method makes it possible to obtain a greater throughput while keeping the amount of sediment in the pressed liquid phase at the same low level such that a product of equal quality can be produced at an improved economic efficiency.
