Indexing belt filter (BF)

The indexing belt filter of type BF is a continuously operating vacuum filter that can be used to filter solid suspensions gently and reliably. The suspension is fed from above and the filter cake forms on the belt. A vacuum is applied under the belt, which sucks the filtrate through the belt. The cyclical operation of the belt with stationary vacuum trays ensures sharp filtrate separation. The quality of the filter cake is achieved via further process steps such as washing, steaming, drying or pressing.
