The New Concentration Process of Cyclone with Concentrator

The cyclone can synthesize a new type of concentration process with the concentration unit. Using the rapid concentration effect of the cyclone, most of the coarse-grained tailings that are easy to thicken are separated from the tailings in advance, and the cyclone overflows into the thickener for concentration. It greatly reduces the load of the thickener, avoids running and mixing of the thickener, and at the same time can quickly obtain high-concentration sedimentation, improve the tailings processing capacity, and facilitate the transportation of subsequent processes.

The requirement for tailings sand is to remove fine-grained mud to obtain high-concentration sedimentation. The equipment that can be selected are thickeners, desilter buckets, rake classifiers, spiral classifiers, and cyclones. Among them, the utilization rate of the cyclone is very high, and the overall efficiency is also better. Not only the equipment is simple, the configuration is convenient, and the operation flexibility is large, but also the dual purpose of desliming and increasing the concentration can be quickly achieved. Although hydrocyclones have many of the above advantages, they also have shortcomings. When new wear-resistant materials (such as cemented carbide, silicon carbide, etc.) are used to make the wear-resistant parts of the sand outlet and the mine mouth, it can be effectively solved It eliminates the problems of high power consumption and serious high-pressure feed ore wear.

The overflow pipe is mostly circular, and its diameter is usually 0.2-0.3 times the diameter of the hydrocyclone. Its main function is to lead the separated overflow product out of the body smoothly, constantly and continuously. Increasing the diameter of the overflow pipe will increase the overflow flow, but the overflow particle size will also become coarser, and the fine particles in the sedimentation will decrease and the concentration will increase. The diameter of the cylindrical cylinder is the main criterion for distinguishing the size specifications of the hydrocyclone, and has a certain proportional relationship with the sizes of other parts. Increasing the diameter of the cylindrical cylinder can improve the processing capacity of the hydrocyclone, but at the same time the overflow particle size will become coarser, and vice versa.
