Hydrocyclone has many advantages: simple structure, no moving parts; large processing capacity per unit volume; high classification accuracy; low cost of equipment; less space occupied and convenient maintenance; less amount and time of pulp staying in the machine.
Hydrocyclone is not only used in classification operation of grinding cycle, but also used for desliming, dewatering and flotation reagent removal. In addition, it can also be used for heavy suspension mineral processing, and the separation particle size can reach 0. About 1 mm. Gravity suspension beneficiation
The operation of hydrocyclone can be adjusted by pulp pressure, and also by changing the diameter of discharge port and pulp concentration Hydrocyclone for nonmetal mine The cone angle, the size of feed pipe and overflow pipe and the particle size composition of material are used to adjust the operation.
The hydrocyclone in water is shown in Fig. 9: the upper end is cylindrical and the lower part is conical Hydrocyclone for chemical industry The slurry is injected into the hydrocyclone along the tangent direction through the feeding pipe or by the head pressure. As a result, solid particles are subjected to centrifugal forces tens to hundreds of times greater than gravity. There are two kinds of slurry flow in the hydrocyclone because the slurry rotates at a high speed: one is the outflow of downward rotating flow near the cone tube wall; the other is the internal flow rotating upward in the middle of the cone seed cylinder. The hydrocyclone can also use the coarse sand in the ore feeding to enter into the outflow by large centrifugal force, sink along the cyclone wall and discharge from the grit setting mouth, while the fine particles and most of the water in the feed rise in the form of internal flow, and are discharged as overflow through the overflow pipe, so as to complete the unit operation.
