Hydrocyclone structure: The upper part of the Hydrocyclone is a hollow cylinder, and the lower part is an inverted cone that communicates with the cylinder. The two form the working simplified form of the Hydrocyclone. The upper end of the cylindrical cylinder is equipped with a feed pipe tangentially, and the top is equipped with an overflow pipe and an overflow conduit. The manufacturer of Hydrocyclone tells you that there is a grit port at the bottom of the conical cylinder. The parts are connected by flanges and screws. The mine mouth, barrel and grit mouth are usually lined with rubber, polyurethane, silicon carbide or diabase cast stone to reduce wear and replace them after wear.

The working principle of Hydrocyclone: ​​the use of strong centrifugal force to achieve the separation of the mixture under high-speed rotation. For example, the classic static Hydrocyclone uses external pressure to push the feed mixture into the cyclone at a relatively high speed. Since the mixture moves in the tangential direction of the cyclone, this will cause the liquid to rotate along the cylinder wall. Movement, this kind of movement is generally called external swirling flow. The manufacturer of Hydrocyclone tells you that the particles in the external swirling flow are subjected to centrifugal force. If its density is greater than the density of the surrounding liquid, the centrifugal force it receives will become greater and greater. Once the centrifugal force is greater than the liquid resistance caused by movement, the particles will overcome This resistance moves in the direction of the vessel wall and separates from the surrounding liquid. The particles arriving near the vessel wall are pushed by the liquid above the cyclone and move down the vessel wall until they reach the bottom orifice and converge into a suspension with higher viscosity. Discharge from the underflow port. The separated liquid 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 due to the uneven pressure distribution in the radial direction of the liquid when the vortex is generated, the closer 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 tend to the axis direction. move. At the same time, 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 is in the low-pressure zone and part of the liquid moves to it, thus forming an upward rotational movement. , And discharge from the overflow.
Hydrocyclone is mainly used in ore dressing: ① Dense medium cyclone is a common heavy medium separation equipment. ②As a classification equipment in the grinding circuit, especially as a classification equipment for fine grinding. ③ Desliming and thickening the slurry.
