Hydraulic Classifier
Principle
Hydraulic classifier is a kind of hindered settling equipment. Its working principle is that
the water with a certain velocity and pressure flows into the tank, and forms the turbulent
flow through the holes on the steady flow plate into the cylinder. Materials flow into the
cylinder through the inlet, and the large particles sink faster than the small ones in water in
the same proportion; And in the same size and different specific gravities, the particles with
large specific gravity sink faster than the ones with small specific gravity. The materials of
a certain grade will keep the state of suspension with the effect of rising water, the area of
which is called turbulent flow area. The larger particles or the ones with larger specific grav-
ity will sink to the bottom through the turbulent flow area, and are discharged from bottom
valve; the smaller particles or the ones with smaller specific gravity will not get through the
turbulent flow area, but float to the top, and then flow out from the overflow weir and col-
lect to the overflow tank. The voltage detector is inserted in the pulp in turbulent flow area,
and shows the pressure of the pulp. The continuous separations of materials are according to the above process.

Application
It is used for strict classification of silica sand, or other coarse and fine
particle minerals, which can replace the fine screen to control the particle
size;
It is used for the separation of minerals with specific gravity difference.
(Such as the separation of coal and shale in coal industry);
It is used for the dewatering and desliming of minerals.

Due to the effect of rising water, the particle size classification can be
completed for the materials in cylinder body with high production effi-
ciency and low energy consumption;
Equipped with automatic control system, the adjustment of operation
parameters can be simple, convenient and easy to control;
Structure Sketch of Hydraulic Classifier
Special equipment is equipped on the water tank located at the bottom
of the cylinder. The rising water hole will shut down automatically when cutting off the water supply, and the materials
in cylinder body will not block the hole and flow into the tank;
Lined with Xinhai wear-resistant rubber ensures high wear resistance, anti-corrosion, and no iron pollution.
Equipment Structure
The hindered settling device is mainly composed of cylinder body, support, feed inlet, overflow tank, retaining ring,
bearing seat, pressure sensor, electric valve, automatic control system, etc. As shown in the figure.
