Knowledge Base

Q

When choosing a spiral sludge thickening and dewatering machine, factors such as processing capacity, material characteristics, equipment materials, energy consumption, automation level, and after-sales service should be considered. Firstly, determine the processing capacity of the required equipment based on actual needs to ensure it matches the production scale; Next, examine the properties of the material, such as viscosity, solid content, etc., and select the appropriate model.

Q

The inquiry for the imported pre concentrated stacked screw sludge dewatering machine from the UK is for sludge dewatering. Combination of electrical control cabinet system and coagulation reaction tank. The main body of the spiral stacker consists of a fixed ring and a moving ring, through which the spiral shaft passes to form a sealed filtration system. The device is divided into two parts. Composed of a concentration section and a pressing section. Fixed ring and moving ring

Q
