1. A filter press for separating solid components from liquid components of a slurry, comprising:
a press frame;
side beams;
a plurality of filter plates oriented at right angles to a longitudinal direction of the side beams wherein said filter plates are adapted to move along said side beams;
a stationary end arranged on or near one end of the side beams;
a movable head adapted to transport said filter plates along the side beams; and
a press system adapted to exert a closing pressure on said filter plates to press the filter plates against each other,
wherein the press system comprises at least one electrically driven actuator driven by an electrical drive means to generate an axially directed force which is exerted on the filter plates by means of the movable head, wherein said actuator comprises a planetary screw assembly, and an electrical drive unit is arranged to drive said movable head during transportation of the filter plates, wherein said electrical drive unit is separate from said electrically driven actuator and said electrical drive means.
