Horizontal spiral centrifuge is one of our company main products. According to the requirement of the material used, we design the horizontal spiral centrifuge with one motor, two motors driving. At the same time, we design two motors separately on both sides of the machine and motors on the same place of the machine. We also develop three column horizontal spiral centrifuge, used in the separation of coal tar oil, water, slag in the industry, in petrochemical in the separation of oil, water, slag.

Main motor drive at full speed rotating drum, material put into spiral continuously by feed tube, evenly distributed to the spiral discharging port. Under centrifugal force, solid content settles to the drum wall and is pushed out cone drum slag notch by the spiral pusher. Liquid is overflow along the spiral to the drum big end. It form big end set out liquid and small end set out solid.


 

Feature

The decanter centrifuge can be adjusted to suit individual requirements by varying: 

1.   Bowl speed to ensure the exact relative centrifugal force required for optimized separation. 

2. Differential speed, for optimized balance between liquid clarity and solids discharge capacity. 

3. Pond depth in the bowl for optimized balance between liquid clarity and solid dryness.

Technical parameters

Principle of threephase decanter centrifuges is as shown in the above figure. The substance to be separated is fed by the feeding tube into the accelerating cavity of  the spiral conveyor, then enters high speed running drum wall. As the light liquid, heavy liquid and insoluble solid contained in the substance have different specific 
gravities,  the three materials are subject to varied centrifugal forces: the insoluble solid settles into the inner wall (outside) due to its highest specific gravity and subject to maximum centrifugal force; the light liquid settles maximum far away from the inner wall (outside) due to its lowest specific gravity and subject to minimum centrifugal force; and heavy liquid settles in the middle place. The insoluble solid is discharged from the solid discharge port by a spiral feeder which has relative differential speed with the drum; and the light and heavy liquids are then separated by different structures inside the machine wherein the heavy liquid is discharged by the centripetal pump, and the light liquid is discharged via the force of gravity, thus the purpose of three phase separation is achieved.
