Filtration stage: Separation of product cake and mother liquor. The cake thickness can reach 500mm.
Washing stage: The filter cake is further purified, and the residual mother liquor is washed and pre-dehydrated. The filter cake and the washing liquid are mixed layer by layer through a lifting mixer, and then a slurry is formed, and the suspension cake is thoroughly washed.
Drying stage: dehydration and drying of the filter cake. The filter cake is scraped and loosened layer by layer in the mixer. The side wall of the equipment, the bottom of the filter plate, and the moving mixing leaves heat the filter cake together. After the treatment, the hot nitrogen and other media take away the evaporated moisture, so that the material is accelerated-dried, and the drying effect is improved.
