Cloth for belt Press
Description:
Horizontal Belt Filters (HBF) are different from RDFs and RDVFs in that there is no pan. Instead, slurry is pumped onto the horizontal belt surface just ahead of multi-stage dewatering, drying, treating and washing ¡°zones¡±. The final filter cake is discharged using gravity, wires or doctor blades. The belt can be backwashed after cake discharge and before returning to the slurry pick up zone.In all cases above, the original materials used were woven fabrics, ranging from lightweight multi-filaments to heavy mono-filaments weighing up to 40 oz/yd2 or 1350 g/m2. Depending on the type of filter, the discharge system, the product and the process, a very wide range of textiles have been used in these filters with life varying from a few weeks to multiple years.
