disc stack centrifuge is a kind of mechanical equipment for continuous separation of two kinds of liquid or solid-liquid suspensions with density difference by centrifugal sedimentation principle. It has the advantages such as high speed, smooth operation, closed import and export system, low noise and good separation effect.


Widely used in national defense, shipbuilding, environmental protection, power, metallurgy, petroleum, chemical, biochemical, pharmaceutical, printing and dyeing, food (dairy, beer, fruit juice, beverages) and other industries to separate, purify, concentrate, and clear low-concentration turbidity liquids and suspensions.

disc stack centrifuge operating principle

All the parts of the separator contacted with the materials are made of stainless steel, which meets the requirements of food hygiene.

The separator is mainly composed of import and export device, drum, vertical shaft, transverse shaft, fuselage, speed measuring device, brake device and motor. The centripetal pump structure is adopted for discharging material, after separation, the material is discharged by the centripetal pump, the output pressure is high (0-0.5 MPa), which can be directly transported to downstream equipment. Its drum has been accurately checked for dynamic balance, centrifugal friction clutch and large helical gear pair are used to transmit power in power transmission. The separator has the advantages of stable growth, avoiding overload, small vibration, safety and reliability, simple operation and convenient use. The bearings used in the separator all adopt Swedish SKF brand to ensure the operation accuracy of the equipment. If the separator is equipped with PLC electronic control system, the program operation can be realized.

When the turbid liquid was fed into the high-speed rotating drum, it enters the disc stack along the channel, under the strong centrifugal force, the multi-components with different densities form three dynamic concentric rings: a small amount of solid particles with the greatest density move outward and accumulate on the wall of the drum to form the outermost layer; the denser heavy phase liquid is thrown onto the lower surface of the disc and slides down out of the disc area to form an intermediate layer; the denser light phase liquid moves toward the center of the drum to form the innermost layer. Then, the three components are discharged from the drum by their respective channels.
