Abstract
A method of dewatering filter cake in which the cake is supported on a positively driven pervious conveyor belt or filter cloth. The cake is guided about the circumference of a drum, with the drum positively driven at a variable speed of rotation. In the region of the drum, the pervious conveyor belt or filter cloth holds the cake against the periphery of the drum and additional pressing rollers press the filter cloth and cake against the drum. The drum drives the filter cloth in this region through the medium of the filter cake and induces shear effects in the cake. The speed of rotation of the drum is regulated in dependence on the tension existing in the filter cloth.
