1. Modularized design is for easy installtion and transportation.

2. High auto degrees: Consecutive auto feeding, filtering, washing. dewatering, discharging, cloth cleaning improves production efficiency.

3. Fast filter speed: Large particles will settle at the lower layer while small particles upper layer when material goes through sedimentation area. Reasonable structure of filter cake ensures low resistance of liqud for fast filter of thin layer.

4. Convenient filter technology: cake thickness, water vol., counter current decantation stages, vacuum degree, filter speed can be adjusted for optimistic effect.

5. Fine decantation effect: even and thorough multi-stage advenction or counter current decantation makes collection and reuse of mother liquor and washing liquor separately

1. As the drum rotates, it is partially submerged in the feed slurry.
2. Vacuum draws liquid through the filter medium (cloth) on the drum surface which retains the solids.
3. The vacuum pulls air (or gas) through the cake and continues to remove moisture as the drum rotates.
4. If required, the cake can be washed to remove impurities or to extract more product. Additional drying of the cake follows washing.
5. Finally, the cake is discharged from the drum to a conveyor or chute to the next process step.
6. The filtrate and air pulled through the medium flow through internal filtrate pipes and pass though the rotary valve and into the filtrate receiver.
7. The liquid stream is separated from the vapor stream in the receiver.
8. Liquid filtrate is then pumped to the next step in the process.
9. Vacuum is applied using a liquid ring vacuum pump or other means.

Filter is widely used in mineral processing, chemical, petroleum, pharmaceutical, light industry, food, coal and water treatment sectors.
