A filter plate assembly for a filter press is provided. The filter plate assembly includes at least a first filter plate and a second filter plate, which cooperate to define a filter chamber when the first filter plate and the second filter plate are in a filtering position. At least one of the first filter plate and the second filter plate is movable from the filtering position to a discharge position in which a filter cake can be discharged. In other configurations, the filter plate assembly can include a first filter plate, a second filter plate and a center filter plate or frame, which cooperate to define a filter chamber. The center filter plate or frame is movable from a filtering position to a discharge position.

A filter press is disclosed for separating solid components from liquid components of a slurry. The filter press includes side beams and a plurality of filter plates oriented at right angles to the longitudinal direction of the side beams. The filter plates are adapted to move along the side beams. A stationary end is arranged on one end of the side beams and a movable head is adapted to transport the filter plates along the side beams. The filter press includes a press system adapted to exert a closing pressure on the filter plates to press the filter plates against each other. The press system further includes at least one electrically driven actuator adapted to generate an axially directed force on the filter plates by the movable head. The disclosure also relates to a method for separating the solid components from the liquid components of a slurry.

A filter (20) configured to separate the solid components and the liquid components from a slurry. The filter (20) includes a plurality of filter plate assemblies (46) that cooperate to define a plurality of filter chambers (70), each defining a perimeter (96) having an open section (98) when the filter plates (68) are in a closed position relative to one another. Each filter plate assembly (46) includes a closure (104) configured to close the open section (98). Preferably, the closures (104) are movable to an open position to permit a particulate cake to be removed from the filter chambers (70) without separating the filter plates (68).

Disclosed is an arrangement and method for controlling a pressure filter. The arrangement comprises the pressure filter for solid-liquid separation for producing a filter cake and a moisture analyzer for providing an indication of moisture content of the filter cake. One or more controllers may be used for utilizing the indication of moisture content to set a drying time for the solid-liquid separation.
