Minerals & zeolites

High quality and reliable

Our indexing belt filters (type BF) or rubber belt filters (type BFR) are a major component in the production process for many types of minerals and zeolites. A reliable and versatile technical solution is required for safe processing of mineral suspensions and zeolite suspensions with efficient consumption of utilities. Our filters and filtration systems ensure excellent product purity, even for thin cake layers, through single or multiple cake washing steps (including counter-current), integrated vacuum drying and pressing.
