Belt Press Advantages
★ Large amount of sludge processing, low power consumption
★ Simple operation, low labor intensity for workers
★ 24-hour fully automatic continuous operation
★ Simple operation, low labor intensity for workers
★ High dewatering efficiency, high solid content in the cake
★ Extended to 13 meters for a more reasonable structure
Equipment Features
The equipment adopts a split structure, divided into gravity dewatering section and pressing section. The length of the split concentrator can be designed according to the water content concentration of the sludge and user needs, with a large range of length variation. It is particularly suitable for dry discharge of mine tailings, sand making, piling, and river dredging sludge dewatering treatment, making it the first choice for large and medium-sized mines, stone yards, sand yards, piling construction mud, and river dredging dewatering treatment!

Working Principle of Belt Press
It uses a three-bed filter cloth structure, divided into gravity dewatering area and wedge-shaped pressing area, both operating with variable frequency speed control. First, the slurry is fed into the gravity dewatering area for pre-dewatering through natural sedimentation, then the concentrated slurry enters the wedge-shaped pressing area for pressing dewatering, achieving solid-liquid separation through continuous pressing by the pressing rollers.
