The structural feature of the hydrocyclone is a cone with a small angle (usually 10-20b), which is currently one of the effective equipment for thickening and grading slime water. A typical static cyclone is formed by connecting a cylinder and a cone, including the main components such as overflow pipe, underflow pipe, and feed pipe. Its working principle is: the suspension enters the cylinder tangentially through the inlet pipe and spirals downward; the solid particles have a tendency to settle toward the wall of the cyclone under the action of centrifugal force; the coarse particles are subject to greater centrifugal force It moves to the wall of the cyclone and is discharged from the bottom of the cyclone with the outer swirling flow to form an underflow; fine particles are discharged from the overflow pipe with the inner swirling flow before settlement due to the small centrifugal force, forming an overflow. Flow, thus realizing the separation of materials of different particle sizes.
The hydrocyclone has the advantages of simple structure, convenient operation, large production capacity, high separation efficiency, small floor space and no transmission parts, and it is lined with Xinhai wear-resistant homesickness, wear-resistant and anti-corrosion, etc. It has been widely used in selection Desliming, media recovery, slime water concentration and other operations before coal processing have achieved significant economic benefits
