Water-saving combined cyclone classification and concentration device

Abstract

The invention relates to a device for classifying and concentrating fine material. A water-saving combined cyclone grading and concentration device is characterized in that it includes a body, a diversion and flow stabilization cylinder, a primary hydrocyclone, a secondary hydrocyclone, a frame, a central overflow pipe, and a material-water regulator. Slurry, circulating pump; the cavity of the body is equipped with a central overflow pipe, the cavity of the cylinder of the body is equipped with a diversion and steady flow cylinder, the cylinder of the body is provided with a tangential feeding port, and the body of the body is provided with a tangential feeding port. There is a discharge port at the lower end; the lower end of the central overflow pipe is connected with the feed inlet of the material-water slurryer, circulation pump and primary hydrocyclone by a pipe, and the overflow nozzle of the primary hydrocyclone is connected by a pipe and The feed ports of the secondary hydrocyclones are connected, and the overflow nozzles of the secondary hydrocyclones are connected with the tangential feed ports by pipes. The device has the comprehensive characteristics of combined classification, water saving, energy saving, high solid content of the classified product, and strong adaptability to materials.

Description

technical field [0001] The invention relates to a device for classifying and concentrating fine material. Background technique [0002] The amount of tailings produced during the mineral processing of metal ores accounts for more than 70% to 90% of the total. At present, the most promising utilization methods for bulk utilization of tailings are: tailings filling, dry drainage and dry stacking and preparation New Building Materials. An important link in the process of mine tailings utilization is to obtain tailings with a certain particle size and higher concentration. [0003] At present, in the mineral processing process, the classification equipment used to control the particle size and the concentration of the sorting are mainly: various spiral classifiers, hydrocyclones and fine particle screening equipment. Specifically, how to select the classification equipment needs to consider the classification efficiency of the classification equipment used for the pulp. Due t...

AI Technical Summary

Problems solved by technology

However, for the comprehensive utilization of tailings, it needs 70% to 85% or even higher, which cannot meet the needs of tailings utilization.

At present, the classification and concentration used in production are separate equipment. The classification concentration of the fine-grained grade is low, the energy consumption of classification and concentration is high, the energy utilization rate is low, and the water consumption is large, which is not conducive to energy saving and water saving.
