Horizontal vacuum belt filters

Horizontal Vacuum Belt Filter Systems

horizontal vacuum belt filters

Horizontal Vacuum Belt Filters are dedicated to washing applications and drying of concentrates.

Vacuum pulls the slurry through a cloth belt and then through a rubber drainage belt. The slurry is then pulled though the rubber drainage belt into a vacuum pan and into vacuum manifolds that separate the liquid from air. The filter of the horizontal vacuum belt filter uses a screen cloth and rubber vacuum carrier belt in combination. As the movable dams deposits slurry onto the surface of the filter cloth, the product  moves in a horizontal linear direction under the dam to form a cake.
