ZK SEPARATION Decanter for Use in Steelworks
The decanter centrifuge developed by ZK for wastewater purification, waste slag recovery, and pickling sludge treatment in steelworks uses anti-wear protection materials. Through wastewater purification, cooling water and cleaning water can be recovered, and the impermeable residue can be used in other ways. In the dewatering of steel slag residues in steelworks, the use time of its anti-wear protection is greatly extended. Simultaneously, the equipment is equipped with an automatic control system, which can automatically adjust the differential speed according to different loads to achieve the energy-saving goal while earning the maximum dehydration degree. The use of ZK decanter centrifuges in steel mills will effectively improve economic benefits and reduce environmental pollution.
