General Info

Disk stack centrifuge are high-speed centrifuges for the mechanical separation and clarification of mixtures comprising solids and liquids. These machines can be used in a wide range of applications. Due to their special design, disk stack centrifuges work at a higher rotation speed than other centrifuges such as decanters. As a result, the centrifugal acceleration (g-force) generated by a disk stack centrifuge is significantly more powerful than in decanter centrifuges.  Moreover, the  disks  included  provide  a large clarifying area. Thus, it is possible to separate ultra fine solid particles from a liquid and to separate liquid mixtures in an efficient way

Power drive adopts the friction clutch, Transfer power by the fluid, start reliably, prevent overland. The bearings used the machine are SKF grade in Sweden., guarantee working precision of the machine.

The separator adopts the PLC automatic control system, can carry out automatic de- slugging, ability of fitness is stronger, automatic degree is high. Easy to adjust, worker labor strength is opposite to ease, the solids content ratio in the mixture fluid is widely.

Working princple
The motor drives the drum to rotate at a high speed around the main shaft through the clutch helical gear pair. The feed liquid flows from the upper central feeding pipe to the bottom of the drum and flows out to the drum wall space through the lower edge of the disc seat. Under the centrifugal force field, the solid particles with a large proportion in the feed liquid sink to the drum wall and can be discharged through the slag outlet under the control of the sliding drum. After the liquid phase is fully settled by the disc, it moves to the center and is discharged out of the machine by the centripetal pump.

Application
It is mainly used for liquid-solid separation where the solid content is between 1-5% and the solid particle diameter is greater than 0.5 μ M. For example, the separation and clarification of oils: vegetable oil, animal oil, fish oil, crude oil, various fuel oils and lubricating oils, and the clarification of dairy products; Food: fruit juice clarification, beer separation, separation and clarification of fermentation broth in fermented brewing products; Pharmacy: extraction of vaccines, mycelium, glucose, insulin, antibiotics and vitamins. Chemical industry: solvent of dry cleaning agent, zinc plating solution, aluminum sulfate solution, tar water mixture, PVC, polypropylene, polyethylene, silver (in film processing) and recovery of catalyst and magnet ore; Traditional Chinese medicine: separation and clarification of plant extracts.  

Main features
♦ Small size, easy for workers to operate and occupy less workshop space.
♦ The motor has low power and consumes less electric energy.
♦ Centripetal pump structure is adopted at the outlet of the separator, and the discharged liquid phase can be directly transmitted to the downstream equipment.
♦ There are two kinds of slag discharge modes, which can be automatically controlled by PLC or manually controlled.
♦ Special structure is adopted in the drum, with large processing capacity and good clarification effect.

Material selection:
 ♦ Stainless steel 304, 321, 316, 316L
 ♦ Body carbon steel or cast iron lining stainless steel material
