Coarse particle tailing discarding sorting system based on hydraulic flotation technology

Abstract

The invention relates to a coarse particle tailing discarding sorting system based on a hydraulic flotation technology, which comprises a high-pressure roller mill, a vibrating screen, a pulp mixing barrel 1, hydraulic flotation equipment, traditional mill equipment, a hydraulic classification cyclone, a pulp mixing barrel 2, traditional flotation equipment and other operation units. The high-efficiency and low-energy consumption high-pressure roller mill is mainly selected, raw minerals are crushed to an appropriate coarse particle size range, then the coarse particle minerals are sorted andgraded in advance through the hydraulic flotation equipment, obtained low-grade coarse particle tailings can be directly discarded and meanwhile high-grade concentrates are enriched for subsequent flotation. All operation units of the sorting system operate in a combined mode, abrasion of the mill is reduced, the total energy consumption of ore grinding is reduced, and the ore dressing treatment capacity can be improved. The total flotation process is expected to be shortened, and the ore grinding-ore dressing operation cost is reduced.

Description

technical field [0001] The invention relates to the field of non-ferrous metal beneficiation, in particular to a sorting system based on hydraulic flotation technology for throwing tails of coarse particles. Background technique [0002] Mineral resources are an important material basis for the survival and development of human beings, and are also the focus of international politics, economy, military affairs, and people's livelihood. Therefore, the demand for energy saving, consumption reduction, and efficiency improvement of mineral processing plants is increasing day by day. At present, in mineral processing plants, the energy consumption of ore grinding has always been high, and its energy loss accounts for more than 60% of the total energy consumption of mineral processing, while the wear and tear energy consumption of steel and other materials accounts for about 50% to 70%. In the mid-1980s, the first high-pressure roller mill officially entered the production of crus...

AI Technical Summary

Problems solved by technology

High-pressure roller mill technology has been recognized as an advanced grinding technology at present. It has obvious advantages such as more crushing and less grinding, early throwing, energy saving and emission reduction, saving energy consumption, and improving grinding efficiency. However, under the characteristics of more crushing and less grinding of high-pressure roller mills, minerals The crushing particle size is relatively large, but there is no efficient coarse particle sorting equipment in the prior art, that is, coarse particle size is carried out through traditional sorting equipment. The tailing efficiency of particles is low
