There are many parameters related to hydrocyclone, which are structural, process and feed properties, and often interrelated, mutually restrictive, difficult to adjust and control, which is also an important reason why it is difficult to widely use in China. . The main parameters related to it are briefly described below.
(1) Cylindrical cylinder diameter and height. This diameter is the main size of the cyclone and it has a certain relationship with the dimensions of other components. This increase in diameter increases the processing capacity, but the overflow particle size becomes coarser and vice versa. In order to classify the fine particle material and increase the throughput, a method in which a plurality of small cyclones are connected in parallel is usually employed.
The height of the cylindrical cylinder has an influence on the residence time of the slurry in the cyclone, that is, the classification efficiency, but it is not too high or too low, generally 0.6 to 1.0 of its diameter.
(2) The diameter of the mine mouth. This diameter is usually 0.08 to 0.25 of the diameter of the cyclone, and greater than this value can increase the throughput, but the classification efficiency is reduced. The feed port is also often made rectangular.
(3) Diameter of the overflow pipe. This diameter is generally 0.1 to 0.4 of the diameter of the cyclone and can be used to adjust the relative yield of overflow and grit. The diameter of the overflow pipe increases, the overflow flow increases, the overflow particle size becomes coarser, and the fine particles in the grit are reduced and the concentration is increased.
(4) The diameter of the grit chamber. Generally, the diameter of the grit chamber is increased, the overflow flow is reduced, the overflow particle size is thinned, and the amount of sedimentation is increased, the concentration is lowered, and the fine particles are increased, but the treatment amount is not significantly affected. The diameter of the grit chamber becomes smaller, the discharge of grit is reduced, and the phenomenon of “running rough†occurs in the overflow. If it is too small, the coarse particles will accumulate at the top of the cone, resulting in blockage. The appropriate diameter of the grit should be such that the grit is discharged in an umbrella shape with an angle of 400 to 700. The ratio of the diameter of the grit chamber to the diameter of the overflow pipe is generally 0.4 to 0.8.
(5) Overflow tube overflow depth. If the insertion is too shallow, the coarse particles will not reach the overflow in the centrifugal force field, and the deep insertion will cause the bottom coarse particles to enter the overflow, which will reduce the classification efficiency. The overflow depth of the overflow pipe should generally be 0.7-0.8 of the height of the cylindrical cylinder.
(6) The taper angle of the conical cylinder. This increase in taper angle reduces the height of the equipment and increases the average radial flow rate of the slurry. At the same time, as the flow blocking effect of the cone increases, the upward flow velocity of the slurry increases, causing the overflow particle size to become coarse. Therefore, when the separation particle size is coarse, a large cone angle cyclone (30°~60°) is used, and when the separation particle size is fine, a small cone angle cyclone (15°~30°) is used, and when the mud is removed, a swirl angle smaller is used. (10 ° ~ 15 °).
(7) Feeding pressure. The commonly used ore pressure is 49~157kPa (0.5~1.6kgf/cm2). The ore pressure is directly related to the treatment volume and separation particle size. Increasing the ore pressure can reduce the graded particle size and increase the throughput, but it will significantly increase power consumption and equipment wear. The ore pressure should be stable during normal operation.
(8) Properties of the pulp. Mainly refers to the density, particle size and pulp concentration of the ore. The higher the density of the ore, the finer the graded particle size. When the concentration of the slurry is large and the mud content is high, the viscosity and density increase, and the movement resistance of the particles is increased, so that the classification granularity becomes coarse. vice versa. The optimum slurry concentration is usually determined experimentally on a case-by-case basis.
