 Structures and properties

Model LW centrifuge is the mechanical equipment used for continuously separation the materials in the suspension with density difference, by the principle of centrifugal settling. The basic principle is the drum and the spiral feeder rotate in the same direction but with a certain speed difference; The material is led into the feeding spiral inner cylinder via the feeding pipe and after speeding up, enters the drum; Under the action of the centrifuge force field, the relatively heavier solid-phase material deposits on the drum wall forming the residue layer; The solid-phase residue is continuously pushed by the spiral feeder to the conic end of the drum and after dehydration in the drying area, is discharged under full-speed running. It enjoys such features as compact structure, continuous operation, smooth running, strong adaptability to the separation material, large handling capacity, convenient maintenance, etc.

Order Notice
