FILTER CAKE BLOW DRYING FOR FILTER PRESSES

Residues of liquid can never be completely excluded in the finished filter cake or between the filter cake and the filter cloth. This results in high and unnecessary disposal or transport costs. The drying of the filter cake is done using compressed air. The compressed air of the pressure plate shoots through the filter cake to the wash plates. The residual water drains off via the filtrate drains provided for this purpose. The compressed air presses part of the capillary water out of the filter cake. In this context, the adhering capillary water between filter cloth and filter cake is reduced. This leads to an improvement of the dissolving behaviour and the dry matter content (DM content) in the filter cake.
