Embodiment 1

[0042] Such as figure 1 As shown, the present invention discloses a mine magnetic separator, comprising a crushing mechanism 1, a feeding mechanism 2, a conveying mechanism 7, and a magnetic separation mechanism 3; Transported into the feed mechanism 2, the output port of the feed mechanism 2 is opposite to the entrance of the magnetic separation mechanism 3.

[0043] The crushing mechanism 1 includes a hollow cylinder, and the upper and lower ends of the cylinder are respectively provided with a feed port and a discharge port. The screen part, the screen part is located outside the acceleration part; the surface of the crushing wheel cooperates with the side wall of the turning chamber to form a turning surface for magnetic ore turning; magnets are arranged in the acceleration part, and the screen part has through holes. The design of the turning chamber makes the minerals turn over, and the magnetic ore that enters first is used for turning over and then collides with the m...

Embodiment 2

[0051] A mine magnetic separation system, a crushing mechanism 1, a feeding mechanism 2, a conveying mechanism 7, a magnetic separation mechanism 3, and a controller;

[0052] The crushing mechanism 1 includes a hollow cylinder, and the upper and lower ends of the cylinder are respectively provided with a feed inlet and a discharge outlet. There are two upper and lower turning chambers in the cylinder, and the two turning chambers are respectively equipped with a disc-shaped crushing wheel. The crushing wheel It includes an acceleration part and a screen part, the screen part is located outside the acceleration part and has a through hole on the screen part; the side wall of the turning chamber has a turning part and a funnel part, and the crushing wheel is located in the middle of the funnel part, and the surface of the crushing wheel The surface of the turning part cooperates to form a turning surface for magnetic ore turning. The first output channel is formed between the cr...

Embodiment 3

[0059] Based on the magnetic separator of embodiment 1 or the magnetic separation system of embodiment 2, its magnetic separation method is:

[0060] Step 1: Put the ore particles with ore particles into the large and small crushing mechanism 1 for crushing, and the crushed ore particles fall onto the conveying mechanism 7. The conveying mechanism 7 includes a conveying belt, an equalizing frame on the conveying belt, and the upper part of the conveying belt The leveling device is arranged at intervals, and the leveling device scrapes the ore particles into the uniform material frame, and the conveyor belt quantitatively transports the ore particles to the feeding mechanism 2;

[0061] Step 2: The small ore particles fall into the magnetic separation mechanism 3 through the mesh of the screen, and the large ore particles slide down along the surface of the screen, and fall in the mesh area corresponding to the size of the ore particles, and are crushed After falling into the m...

Abstract

The invention relates to the field of mine magnetic separation, in particular to a mine magnetic separator. The mine magnetic separator comprises a crushing mechanism, a feeding mechanism, a conveying mechanism and a magnetic separation mechanism. The conveying mechanism is used for conveying magnetic ore output by the crushing mechanism into the feeding mechanism. An output port of the feeding mechanism is opposite to an inlet of the magnetic separation mechanism. The structure is suitable for magnetic ore screening of mines, in-situ magnetic separation is facilitated, and the magnetic separation cost of the ore is reduced. In addition, magnetic separation of the magnetic ore crushed by the crushing mechanism is more facilitated, the magnetic ore is evenly distributed conveniently through the feeding mechanism, production and application of the equipment are convenient, and the magnetic separation efficiency and the recovery rate of the magnetic ore are improved. Crushing is conducted by sufficiently utilizing the characteristics of ore grains, the crushing precision is higher, and safety and effectiveness of equipment application can be guaranteed through the structure. More specific collision is conducted on the magnetic ore through characteristics of the magnetic ore and non-magnetic ore, the service life of the equipment is prolonged, and the feeding mechanism has re-screening and crushing functions.

Description

technical field [0001] The invention relates to the field of mine magnetic separation, in particular to a mine magnetic separator. 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] Because the magnetic separation particles of magnetic ore are different during the magnetic separation process, it will affect the magnetic separation effect. Therefore, it is necessary to use a c...
