Principle of sand washing and spiral sludge dewatering machine: After gravity concentration in the concentration section, the sludge is transported to the dewatering section. During the process, as the filter gap and pitch gradually decrease, and the back pressure plate blocks it, a great internal pressure is generated, and the volume continuously decreases, achieving the purpose of full dewatering
Principle of sand washing and stacking screw sludge dewatering machine:After gravity concentration in the thickening section, the sludge is transported to the dewatering section. As it moves forward, with the gradual reduction of the filter gap and pitch, as well as the blocking effect of the back pressure plate, a great internal pressure is generated, and the volume continuously decreases, achieving the goal of full dewatering.
