Vacuum belt filters are generally used in materials with crystalline coarse solids. The liquid in the material fed on the belt is sucked from the vacuum chamber under the belt and separated from the solid. Belt width 1000mm. with 3000mm. ranges between.
While performing an efficient filtration with their size and high capacity, cake washing can be done very easily for special products at the same time. One of the vacuum belt filters, which can be produced in two different designs, is vacuum drawer and the other is conveyor belt types with vacuum channels.
Vacuum drawers moving at the same speed with the vacuum drawer type filter cloth suck the filtrate under the filter cloth with vacuum, and when it reaches the forward limit, it comes back quickly and starts to filter the newly fed part. Meanwhile, the cake on the filter cloth, which continues to move, is separated from the filter cloth with a scraper.
In the vacuum channel conveyor belt type, while the filter cloth is advanced on a special band and by this band, the filtrate is sucked from the vacuum channel under the holes on the band surface.
