Rubber Belt Filter
Description
The BHS Rubber Belt Filter is a continuous vacuum filtration system designed for cake washing and drying of high-solids slurries. It features a filter cloth supported by a rubber, EPDM, or synthetic drainage belt. Filtrate tubes separate the filtrates into dedicated receivers for recovering mother liquor, wash filtrates, counter-current washing, and drying gas. The drainage belt moves on specially coated rollers, eliminating the need for air and water sliding systems.
The roller-supported belt enables fast filtration and large filter areas, up to 200 m², ideal for handling heavy cakes. The system can also integrate steaming and counter-current washing as part of the design.
