Abstract

A filter press for separating solid components from liquid components of a slurry. The filter press includes a compression system coupled to a stationary pressure plate of the filter press. The compression system includes at least one electrically operated compression actuator having a planetary screw assembly, and a transport system coupled to a displaceable pressure plate of the filter press. The transport system includes at least one electrically operated transport actuator having a rack and pinion drive assembly. The compression system rigidly connects to the transport system so as to form, for each respective pair of compression actuators and transport actuators, a common actuator link which extends linearly from the stationary pressure plate to the displaceable pressure plate along the longitudinal dimension. A retrofitting kit for a filter press, a method for replacing an existing compression and transport system for a filter press and a method for controlling a filter press are set forth.
