A hydrocyclone is a classification device for accelerating the sedimentation of ore particles by using centrifugal force. It needs pressure ore feeding, so it consumes large power, but it has small floor area, low price, large handling capacity, high grading efficiency, and can obtain fine overflow product, and is mostly used for grading equipment in second stage closed circuit ore grinding. The hydrocyclone is mainly used for classification, separation, concentration and desliming in the mineral separation industry, and when the hydrocyclone is used as classification equipment, the hydrocyclone is mainly used for forming a grinding classification system with a grinding machine; when the device is used as desliming equipment, the device can be used for desliming in a gravity separation plant; when the concentrated tailing is used as concentrated dewatering equipment, the concentrated tailing can be sent to fill underground mining tunnels after being concentrated. The hydraulic cyclone has no moving part and simple structure; the production capacity per unit volume is large, and the occupied area is small; the grading efficiency is high (reaching 80-90 percent), and the grading granularity is fine; low cost and less material consumption. Most of hydrocyclones adopted in the copper ore dressing plant of the large nonferrous mine at the present stage depend on the separation form of a carbon steel shell and lining rubber, and the structure form is relatively simple, convenient to assemble/disassemble and easy to produce. However, the cyclone is not an optimal structure, the structure cannot ensure the cut-in curve of the material, cannot ensure the seamless connection of the rubber lining and the carbon steel shell, has the possibility of rubber lining bulge and rubber turnover, cannot ensure the effective laminar flow of the material in the operation and has influence on the indexes of overflow and underflow.
