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
[0003] In the prior art, there is a Chinese invention patent application named Vibrating Fluidized Bed Dry Magnetic Separator. The magnetic separator introduced in this invention is not suitable for material movement due to the horizontal arrangement of the vibrating feeding trough. Magnetic separation, such as the magnetic separation of magnetite after rolling; and because the magnetic force of the magnetic system is constant in the length direction of the vibrating plate, it is not possible to separate only high-grade ore; Magnetic separation is not possible; and there is no dust suction device, which cannot absorb the non-magnetic dust wrapped on the magnetic material, so that these materials cannot be sorted out, so it is not suitable for magnetic separation of materials after rolling
However, due to magnetic separation only by magnetic force, it is not possible to separate only high-grade ore

Abstract

The invention relates to a magnetic separation device and particularly relates to an oblique grading and magnetic separation device. The oblique grading and magnetic separation device comprises a magnetic separation belt and wheels which support the magnetic separation to form a triangle, wherein the magnetic separation belt comprises a horizontal segment and an oblique segment, and a wheel at the intersection of the horizontal segment and the oblique segment is a magnetic roller; a separating magnetic system is arranged inside the oblique segment, a strong magnetic device is arranged between the separating magnetic system and the magnetic roller, and magnetic forces of the magnetic roller, the strong magnetic device and the separating magnetic system are continuous; and a strong fan is arranged below the strong magnetic device, the magnetic field intensity of the strong magnetic device is stronger than that of the separating magnetic system or the magnetic roller, and strong fan cannot blow magnetic minerals at the strong magnetic device down. According to the oblique grading and magnetic separation device, the problems of magnetic inclusion and magnetic packaging are solved; by virtue of the design, the magnetic separation efficiency of the device can be improved, and the grade of concentrates can be improved; and by virtue of continuous magnetic forces of the magnetic roller, the strong magnetic device and the separating magnetic system, the situation the magnetic minerals fall at the oblique segment is prevented. Compared with existing magnetic separation devices, the oblique grading and magnetic separation device has the advantages that the quantity of magnetically included and packaged dust is reduced by 20%-50%, and the grade of the concentrates is improved by 10%-15%.

Description

technical field [0001] The invention relates to a magnetic separation device, in particular to an inclined grading magnetic separation device. 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] In the prior art, there is a Chinese invention patent application named Vibrating Fluidized Bed Dry Magnetic Separator. The magnetic separator introduced in this invention is not suita...
