Wet magnetic separation iron ore concentrate concentration and classification cyclone and process thereof

Abstract

The invention discloses a wet magnetic separation iron ore concentrate concentration and classification cyclone and a process thereof, and belongs to the technical field of classification cyclones. The cyclone comprises a material receiving bent pipe, the bottom end of the material receiving bent pipe is connected into a cyclone assembly, a grading and flow dividing assembly is arranged in the cyclone assembly, a centrifugal assembly is arranged at the side end of the bottom end of the grading and flow dividing assembly, and the bottom end of the grading and flow dividing assembly is connected with a flow dividing and collecting assembly. The centrifugal force of rotational flow is effectively improved, materials are better separated, the materials with different particles can be effectively graded, the grading efficiency is improved, grading can be rapidly and accurately carried out, output can be effectively carried out, the flow dividing conveying efficiency is guaranteed, the flow dividing classification convenience is improved, the filtering speed is guaranteed, the cyclone force is prevented from being reduced during filtering, cyclone filtering is effectively carried out, the collection convenience is improved, and batch treatment can be carried out according to classified materials.

Description

technical field [0001] The invention relates to the technical field of classifying cyclones, in particular to a wet-type magnetic separation iron concentrate concentration classifying cyclone and a process thereof. Background technique [0002] There are many kinds of metal ore resources in my country, but most of them are poor, miscellaneous and fine in quality. In order to solve the outstanding problems faced by domestic metal mining enterprises in the aspects of economy, technology and environmental protection in mining development, they have actively introduced, digested and absorbed foreign new and efficient mining production process equipment, high-pressure roller mills, wet permanent magnet cylinders, etc. Type magnetic separator and cyclone are commonly used equipment in iron ore beneficiation plants. When the closed-circuit product of high pressure roller mill and 3mm sieve undergoes wet magnetic separation and waste operation, the concentrate product concentration ...

Problems solved by technology

In order to solve the outstanding problems faced by domestic metal mining enterprises in the aspects of economy, technology and environmental protection in mining development, they have actively introduced, digested and absorbed foreign new and efficient mining production process equipment, high-pressure roller mills, wet permanent magnet cylinders, etc. Type magnetic separator and cyclone are commonly used equipment in iron ore beneficiation plants. When the closed-circuit product of high-pressure roller mill and 3mm sieve undergoes wet magnetic separation and waste operation, the concentrate product concentration is low, and the concentrate enters The spiral classifier performs grading operations, resulting in a low overflow concentration of the classifier and is difficult to control. At the same time, the overflow particle size of the classifier cannot be controlled, resulting in abnormal operation of the grinding and grading system, and there is no way to accurately classify wet materials, resulting in classification efficiency.
