3 phase liquid-liquid-solid Decanter centrifuges, also called
tricanter, Taking advantage of the principle that the heavy
liquid,light 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.It is the popular machine
throughout the world and widely used in the fish oil, palm oil,
kitchen waste oil separation etc.

The decanter is driven by two motors. The main motor drives the
bowl and the housing of differential mechanism to rotate through
belt, while the auxiliary motor drives through the belt pulley the
input shaft of the differential mechanism to rotate, which, after
speed change, drives the helical to rotate. In this way the bowl
and helical rotate in the same direction but with certain
When the material to be processed (blended liquid consisting of
solid phase and liquid phase) enters the inner cavity of the
helical propeller through feeding pipe, after being accelerated by
the two-way conical accelerator, it flows out of the material
outlet, and flows into the bowl wall through inner cloth cylinder.
The light, heavy and residue phases that make up the suspending
liquid, under the action of different centrifugal force, the
residue phase quickly subsides onto the inner wall of the bowl, and
the heavy phase adheres close to the surface of the residue phase
rather slowly, while the light phase adheres close to the surface
of the heavy phase rather slowly, forming a dividing plane between
the two phases.
As the sedimentation of heavy phase increases, the top end of
helical blade enters into the sedimentation layer of heavy phase.
At this time the bowl and helical propeller are rotating in the
same direction at high speed and with a certain difference in
This relative difference in rotation speed enables the helical to
propel heavy phase particles to move toward the material outlet at
the small end, whereas the light phase, through the helical
passage, flows toward the liquid phase outlet at the large end, and
flows out through the overflow plate with different R values.
