Horizontal Continuous Decanting Centrifuge Separator With Solid Control Systerm
Brief Introduction
The traditional Kaolin grading Horizontal screw centrifuge produced by HONGJI has been widely used in kaolin production by the domestic well-known manufacturers since the 1990s. And now the domestic traditional grading methods of horizontal screw centrifuge cannot meet the requirements of the users. Due to the higher requirements of customers to equipments in abrasion resistance, handling capacity, recovery, mechanical reliability, economical efficiency and so on, HONGJIfirst developed the Kaolin grading Nozzle Horizontal Screw Discharging Centrifuge in China.
The theory of this centrifuge subverts the traditional pattern that underflow discharges from solid slag discharge mouth while the overflow discharges from the liquid slag outlet.
Separation principle
Taking advantage of the principle that the light liquid, heavy liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved.Screw Centrifuge
In the gravity force field or centrifugal force field, the light liquid phase, the heavy liquid phase and the solid phase with different density and mutually insoluble in the mixed liquid, respectively gain different sedimentation speed, and thus separate and stratify. In the gravity force field it is called gravity separation, while in the centrifugal force field it is called centrifugal separation.
Gravity separation
On account of difference in density, the mixed liquid in the container, after a period of time, is gradually divided into 2 layers. The heavy phase particle of the mixed liquid deposits to the bottom of the container, while the light phase one suspends to the upper surface. A rather distinctive dividing plane forms between the light and heavy phases. The separation speed is affected by the difference in density between the light and heavy phases that make up the mixed liquid. The larger the difference in density is, the faster the separation speed will be.
Decanter centrifuges have wide process capacity to meet all ranges as per drilling program.It is commonly and widely used used for oilfield and gas well operations providing efficient solids control while significantly reducing the operator's total mud cost and minimize waste disposal volumes.
