Main Coal Dewatering Centrifuge Working Principle

Centrifuge TypeMaterial TypeWorking Principle
Horizontal Vibratory Centrifuge Coarse Coal Dewatering The solid-liquid separation is carried out by the principle of vibration and centrifugal spin-drying, no scraper and screw inside the bowl
Horizontal Screen Scroll Centrifuge Fine Coal Dewatering The solid-liquid separation is carried out by the principle of centrifugal spin-drying, the liquid is centrifugally separated by a screen basket, and the solid is discharged by an internal scraper
Screen Bowl Decanter Centrifuge Ultrafine Coal Dewatering The solid-liquid separation is carried out according to the principle of centrifugal sedimentation and centrifugal filtration. The last section of bowl is provided with screen mesh. The liquid can be discharged through the liquid overflow port of centrifuge and screen basket mesh, and the solid is pushed to the discharge port by the internal screw.
Solid Bowl Decanter Centrifuge Coal Tailing Dewatering The solid-liquid separation is carried out by high speed centrifugal force. The liquid can be discharged through the liquid overflow port of centrifuge, and the solid is pushed to the discharge port by the internal screw.
