Hydrocyclone consists of a hollow cylinder in the upper part and an inverted cone communicating with the cylinder in the lower part. The two constitute the working cylinder of Hydrocyclone. In addition, Hydrocyclone also has feed pipes, overflow pipes, overflow pipes and grit ports.

Hydrocyclone uses a sand pump (or height difference) at a certain pressure (usually 0.5 to 2.5 kg/cm) and a flow rate (about 5 to 12 m/s) to spin the pulp into the cylinder along the tangential direction, and then the pulp is quickly The speed rotates along the cylinder wall to generate centrifugal force. Under the action of centrifugal force and gravity, the coarser and heavier ore particles are thrown out.
Hydrocyclone is mainly used for classification, separation, concentration and desliming in the mineral processing industry. When Hydrocyclone is used as a classification device, it is mainly used to form a grinding and classification system with a mill; when used as a desliming device, it can be used for desilting in a gravity separation plant; when used as a thickening and dewatering device, it can be used to concentrate the beneficiation tailings Sent to fill underground mining tunnels.
Hydrocyclone has no moving parts, simple structure; large production capacity per unit volume, small area; high classification efficiency (up to 80% to 90%), fine classification granularity; low cost and low material consumption.
The suspension enters the Hydrocyclone along the tangential direction from the feed tube at a higher speed. Due to the restriction of the outer cylinder wall, the liquid is forced to make a top-down rotational movement. This movement is usually called external swirling or descending swirling. sports. The solid particles in the external swirling flow are subjected to centrifugal force. If the density is greater than the density of the surrounding liquid (this is most of the cases), the greater the centrifugal force it bears. Once this force is greater than the liquid resistance caused by the movement, the solid particles will Will overcome this resistance and move to the direction of the vessel wall and separate from the suspension. The particles that reach the vicinity of the vessel wall are pushed by the continuous liquid, move down the vessel wall, and gather near the bottom orifice to form a greatly thickened suspension. The underflow port is discharged. The manufacturer of Hydrocyclone tells you that the separated and purified liquid (of course there are some fine particles) rotates downward and continues to move. After entering the cone section, the inner diameter of the hydrocyclone gradually shrinks and the liquid rotation speed increases. The manufacturer of Hydrocyclone tells you that the pressure distribution along the radial direction is uneven when the liquid generates vortex motion, the closer it is to the axis, the smaller it is, and it approaches zero when it reaches the axis, which becomes a low pressure zone or even a vacuum zone, causing the liquid to move in the axial direction. . At the same time, the manufacturer of Hydrocyclone tells you that because the bottom orifice of the hydrocyclone is greatly reduced, the liquid cannot be quickly discharged from the bottom orifice, and the overflow orifice in the center of the top cover of the cyclone chamber causes a part of the liquid to move to it due to the low pressure area, thus forming Rotate upwards and discharge from the overflow port.
