Xinhai cyclone unit can be equipped with automatic control system to set parameters for black metal, non-ferrous metals, industrial minerals, non-metallic minerals and building materials. It also checks and adjusts the liquid level of pump tank, slurry flow, outlet pressure, slurry concentration, and motor rotation speed to ensure the indexes are within optimal range.Xinhai hydrocyclone unit adopts computer to select model. As long as the users fill in the relevant parameters, the program will choose the most suitable cyclone number to make the operation more efficient and meet the requirement of classification. In addition, Xinhai cyclone unit is combined with other equipment to form classification group, which can improve the machine processing capacity by more than 15%, and multifunction screen in combination equipment can automatically return coarse particles in overflow to the mill.
