3986 rpm Decanter Centrifuge product introduction
The 3986 rpm decanter centrifuge is a horizontal solid liquid separation equipment used for continuous processing of slurry materials. It is constructed with stainless steel components and designed for handling oil-based, water-based, and mixed suspensions. The machine separates solid particles from liquid phases based on density differences under high centrifugal force. It is suitable for edible oil production, drilling waste treatment, mining slurry processing, and chemical separation industries where efficient dewatering, clarification, and material recovery are required.
Working Principle
The decanter centrifuge operates by feeding slurry into a rapidly rotating horizontal bowl. Centrifugal force generated at 3986 rpm separates heavier solid particles from lighter liquid phases. Solids settle on the bowl wall and are continuously conveyed by a screw conveyor toward the discharge end due to differential speed between the bowl and conveyor. The clarified liquid flows in the opposite direction and exits through overflow outlets. This continuous separation process ensures efficient solid liquid separation in industrial applications.
