Abstract

The invention relates to the technical field of preparation equipment, and particularly relates to a high-speed vertical magnetic resorting system of a composite magnetic field and a sorting method thereof. According to a high-speed vertical magnetic resorting machine of the composite magnetic field, an outer barrel is arranged on the outer side of a magnetic system fixing barrel, a gap is left between the outer barrel and the magnetic system fixing barrel, and the outer barrel rotates; the magnetic field intensity and magnetic field depth of magnetic systems and the size and thickness of magnetic blocks are from high to low and from large to small in a rotating direction according to different functions of the magnetic systems in a feeding area and a sorting area. By adopting the composite magnetic field, the arrangement of the beneficiation magnetic field is greatly optimized, the beneficiation accuracy is increased, and additionally, the quantity efficiency and the quality efficiency for mineral separation are improved. A housing rotating mode is adopted, so that the number and weight of rotating components are greatly reduced, the rotating load of the equipment is reduced, andenergy consumption of the whole equipment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a composite magnetic field high-speed vertical magnetic gravity separation system and a separation method thereof. Background technique [0002] Iron ore mostly uses horizontal magnetic separation equipment for beneficiation, but due to structural limitations, horizontal magnetic separation equipment cannot be enlarged, the processing capacity cannot be greatly increased, and there are problems such as line speed limit, high transmission power, and large loss of ineffective power. ; During high-speed operation, a large amount of eddy current heat will be generated, which will increase the transmission power and increase the energy consumption of the beneficiation operation, and the centrifugal force will not be effectively used during operation, and the beneficiation efficiency will be low. At present, there are some vertical separators, but there are many de...

AI Technical Summary

Problems solved by technology

However, the following problems exist in the use of the above equipment: 1. The iron ore powder will accumulate locally in the separator, resulting in unreasonable tailing

2. In order to facilitate the installation of the sorting magnetic system, the outer casing of the equipment is made of steel and metal materials. During the rotation of the metal casing, the magnetic force lines are cut to generate magnetic eddy currents. The linear velocity of the casing is limited, and high-speed rotation will cause heat generation and energy consumption to increase significantly.
