The principle
Hydrocyclones are used for continuous separation and
dephlegmation of suspended particles from fluids. They are
operated at large suspension throughputs with high
effectiveness.
Hydrocyclones use the centrifugal force to accelerate
sedimentation by tangentially entering of the suspension flow
to be separated into the hydrocyclone, where a circular motion
is forced on the fluid. In this range a centrifugal
acceleration dependent from the flow rate and the diameter of
the hydrocyclone takes effect on the suspended solid particles. The coarse solid particles concentrate at the circumference of
the hydrocyclones, and the fine particles in the centre.
The
clarified fluid is drawn off by an immersion pipe (vortex
finder) in the upper range, the thickened suspension runs off
below (apex finder).
Throughput and separation behaviour of the hydrocyclone can be
variied by modification of the diameter of apex and vortex
finders and the admission pressure.

Advantages of the solid-liquid separation with hydrocyclones
Upperflow- and underflow nozzles are slightly exchangeable and
are available with various diameters of bore. All components
of the hydrocyclone can be assembled and disassembled quickly.
A graduated range of types enables an adjustment to the
respective product and the requested separation behaviour.
Highest throughput capacities and small space requirement are
achieved by interconnecting of single hydrocyclones to larger
units.
