Experimental Investigations on the Vertical Pressing Filter in the Separation Process of 4A Zeolite

A vertical automatic pressing filter was used for a series of separating, washing and air-drying experiments of 4A zeolite crystallized slurry and qualified slurry. The results showed that, the washing efficiency was not good, so the filter could not be used for washing the crystallized and filtered cake directly. However, the moisture of the filtered cake could be reduced to less than 15%,therefore the filter could be used for separating and air-drying of 4A zeolite crystallized slurry and qualified slurry,and the application of this filter could enormously reduce the washing water consumption in the stirring and washing procedure and the energy consumption in the drying procedure.
