Problems solved by technology

Now public dry magnetic separators, the concentrate grade after beneficiation is often in a range such as 30%-60%, if only high-grade ore is required to be selected, these dry magnetic separators cannot achieve it; Especially after the roller press is applied to the crushing of magnetite, the material handling capacity is quite huge, and the commonly used dry magnetic separator cannot meet the requirements

Abstract

The invention relates to the field of crushing treatment equipment between magnetic ore magnetic separation, and belongs to crushing equipment, in particular to a crushing device for magnetic ore. Thecrushing device comprises a hollow barrel, and a feeding port and a discharging port are formed in the upper end and the lower end of the barrel correspondingly; an overturning part is arranged on the inner side wall of the barrel, and a crushing mechanism capable of rotating in the vertical direction is arranged in the barrel; the surface of the crushing mechanism and the overturning part are matched to form an overturning hook face for magnetic ore overturning; and a magnet is arranged in the crushing mechanism. Due to the design of the overturning part, ore is overturned, the magnetic oreentering firstly is overturned and collides with the magnetic ore entering later for crushing, the equipment losses are reduced, and the situation that ore and the equipment are in rigid collision, and the usability of the device is lowered is avoided; by utilization of the magnet, the magnetic ore and non-magnetic ore are different in speed, so that crushing is conducted through the speed difference; and more targeted crushing on the magnetic ore can be achieved.

Description

technical field [0001] The invention relates to the field of crushing and processing equipment between magnetic ore and magnetic separation, and belongs to crushing equipment, in particular to a crushing device for magnetic ore. Background technique [0002] In the field of mineral processing in metallurgy, mining and other industries, it is necessary to select magnetic materials, such as iron ore. Now the industry is vigorously researching dry magnetic separators. Now public dry magnetic separators, the concentrate grade after beneficiation is often in a range such as 30%-60%, if only high-grade ore is required to be selected, these dry magnetic separators cannot achieve it; Especially after the roller press is applied to the crushing of magnetite, the material handling capacity is quite huge, and the commonly used dry magnetic separator cannot meet the requirements. [0003] During the magnetic separation process of magnetic ore, the magnetic separation particles are diff...
