IBY Industry Centrifuge

Industry Centrifuge is a kind of centrifugal separation machine widely used in industrial production process to separate suspension. Such as in the process of oil drilling, the centrifuge is used in the solid control system of drilling fluid to separate the solid and liquid of drilling fluid, remove harmful solid particles such as cuttings in mud, or recycling barite and other valuable weighting materials, in order to save the mud costs. Except for oil drilling industry, the horizontal screw centrifuge can be used in separation of industrial chemicals, mineral extraction, Sewage and sludge treatment, alcohol extraction, food waste treatment, food separation (edible oil, soy, protein), separation of industrial hemp, coal chemical field and so on.

The structure of centrifuge is horizontal. The driving mode can be motor and hydraulic, it can be controlled by fixed frequency and variable frequency. The centrifuge controlled by frequency conversion can realize wide range stepless speed change conveniently, in addition, it can display the working parameters such as speed, torque, working current and vibration value, etc. It has the advantages of automatic, continuous operation, wide application range, compact structure and large production capacity. The conventional series models of centrifuges are 250, 350, 450, 550, 650, 750, etc. There are two-phase (solid-liquid, liquid-solid) separation centrifuge, three-phase (liquid-liquid-solid, solid-solid-liquid) separation centrifuge. The main parameters of the equipment are drum diameter, drum length, rated speed, drum separation factor, differential speed, processing capacity, main engine power and auxiliary power。

The advantages of horizontal centrifuge are stable structure and easy operation. And the application of centrifuge products will have obvious benefits on environmental protection (such as sewage treatment, sludge treatment), energy saving (petroleum and chemical industry), waste recycling (kitchen waste treatment, oil-based mud and waste oil recycling)

The main motor and auxiliary motor rotate at high speed according to the set speed, a large centrifugal force is produced on the inner wall of the drum. Under the action of strong centrifugal force, the mixture with different density will be gradually stratified, the material with high density will be in the bottom layer, the material with smaller density will be in the upper layer. The greater the centrifugal force, the more obvious the stratification. After driving through the differential, there is a relative speed difference between the drum and the screw pusher, through this speed difference, the screw pusher pushes the bottom material with high density to the outlet of the cone end of the drum for discharge. When the liquid layer depth of the upper material with smaller density is higher than the depth of the overflow end, the liquid phase will overflow automatically. The above process can achieve the purpose of solid-liquid separation. This process is a physical method and will not destroy the original physical performance.
