Decanter Centrifuge
Decanter centrifuge is a horizontal screw decanter centrifuge, which is consisting of a high-speed rotating bowl with high centrifugal G-force. Decanter centrifuge is a widely used equipment in the field of industrial solid-liquid separation. With the advanced manufacturing technology, KINGWELL decanter centrifuge can dewater, clarify and separate the suspensions with 0.002-3mm solids phase particles. According to the characteristics of different materials in different industries, KINGWELL decanter centrifuge is divided into dewatering, separation, and clarifying decanter centrifuge, which is suitable to separate various materials under different working conditions. And we also have the 3-phase decanter centrifuge for separation of liquid, liquid, and solids.
