BHS - Rubber Belt Filter
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.
Durability
BHS rubber belt filters are built to last, even under heavy loads, which helps keep both maintenance and operating costs low. With fewer moving parts, a roller table for belt support, and easy access to the vacuum box, these filters are highly durable and simple to maintain.
High Performance
BHS rubber belt filters are engineered for superior filtration performance. Depending on the application, they can handle suspension capacities of up to 15 m³/m²/h. They also offer the flexibility for one- or multi-stage cake washing.
Flexible Production
Using reliable measuring and control equipment to monitor cake thickness and belt speed, the filter can be easily adjusted to meet specific production requirements. This eliminates downtime associated with retrofitting or adjustments.
