Product Features

Disc separator 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.

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.

Operating Principle

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.


Technical Parameters


Vegetable Oil, Animal Oil Industry

Product Overview

With the continuous improvement of living standards, people pay more and more attention to the quality of edible oil. The quality of oil mainly depends on refining method and the quality of crude oil. In order to improve the quality of oil, our separator provides a variety of solutions for different oils.

Application Fields

Vegetable oils: soybean oil, colza oil, sunflower oil, cottonseed oil, palm oil, corn oil, peanut oil, rice bran oil, sesame oil, safflower oil, etc.


Animal oils: lard, butter, fish oil, pig blood, chicken blood, etc.


Dairy Industry

Product Overview

With the rapid development of dairy industry and the continuous improvement of people's living standards in recent years, the safety of milk and dairy products has been paid more and more attention. People give increased emphasis on drinking safe milk and eating safe dairy products. Our separator is designed specially to make sure that the dairy products soft and fine in the whole separation process, and ensure the quality of dairy products.

Application Fields

Cold milk separation, hot milk separation, hot milk degreasing, cheese concentration, sheep milk degreasing, bovine colostrum extraction, casein production.



Food and Drinks Industry

Product Overview

Various fruits and vegetables are pressed to obtain the initial juice. The initial juice contains a lot of turbid substances, which affect the concentration and the final quality of fruit juice and vegetable juice. Therefore, the fresh juice needs to be purified. Our separator is mainly aimed at the solid impurities and suspended matter in fruit juice and vegetable juice, clarifies and purifies fruit juice and vegetable juice to be more transparent and clear.

In the production process of wine, fruit wine, medicinal liquor production, mechanical clarification and separation is an indispensable and important technique. Our separator can separate the extreme tiny (as less than 1μm) solid particles highly dispersed in suspension from the liquid phase.

Application Fields

General fruits and vegetables: apple juice, orange juice, grape juice, lemon juice, tomato juice, carrot juice, lycopene, etc.

Vegetables: cucumber, spinach, celery, onion, garlic, lettuce, etc.

Tropical fruits: mango, pineapple, passionflower, guava, papaya, etc.

Alcohol drinks: wine, fruit wine, beer, medicinal wine, etc.


Plant Extraction Industry

Product Overview

Plant extract is a kind of product formed by taking plants as raw material, according to the need of the final product, relying on physical and chemical extraction and separation, directional acquisition and concentration of one or more active ingredients in plants without changing the structure of their active ingredients. Mechanical centrifugal separation is one of the most important processes in the separation, concentration and clarification of Chinese herbal and natural plant extracts. According to the features of the final product, it can be divided into oil, extract, powder and lens, etc. Our separator is pollution-free, widely applicable, low cost and simple to operate, it is widely used in the extraction process of natural products such as polysaccharides, polyphenols, flavonoids, glycosides, terpenes, volatile oils, alkaloids.


Application Fields

Pigment, pepper, tea, loquat leaf, honeysuckle, shuanghuanglian, ginkgo leaf, salvia miltiorrhiza, radix isatidis, rutin, momordica grosvenori, rhein, amygdalin, Chinese medicine extraction, etc.

Biopharmaceutical Industry

In the biopharmaceutical industry, mechanical separation is an important process in the production of biopharmaceutical technique. The use of centrifugal separation plays a decisive role in the quality of the final product, the economy of the process and the coexistence of the environmental. The clean, aseptic and closed production conditions put forward a higher requirement for the separator. Our separator can completely meets the requirements of separation equipment in various pharmaceutical production, the parts in contact with the materials are made of high-quality corrosion-resistant stainless steel, which meets the requirements of food hygiene.

Application Fields

Concentration of the microorganisms.

Separation of the extract (penicillin, Escherichia coli, antibiotics, hormones, etc).

Extraction of vitamins.

Concentration and clarification of fermentation broth.

Separation of animal blood.


Chemical Industry

Product Overview

Due to the particularity of the chemical industry,it is a big challenge for the separator when it works with concentrated acid, concentrated alkali, high temperature, flammable and explosive and strength wear. According to the features of different chemical products. We customize each equipment to ensure the optimization of separation effect and the safety of use to meet the needs of customers.


Application Fields

PVC, phosphoric acid, hydrogen peroxide, herbicide, insecticide, viscose, catalysts, latex (synthetic), inks and dyes, lubricant additives, cellulose and derivatives, boiler ash, etc.


Mineral Oil Industry

Our mineral oil separator is mainly used for oil purification and clarification of ships or land power stations and oil regeneration treatment, to remove water, mechanical impurities and some harmful substances, which can reduce the wear of diesel engine and prolong the service life of the machine.In addition, it is also suitable for the clarification and purification of waste oil, cutting fluid and quenching oil, etc.


Application Fields

Waste oil, cutting fluid, quenching fluid, fuel oil, lubricating oil, mixture of oil, water and solid substances, etc.
