An automatic sub-mesh grinding and collecting device for raw ore and its application method

Abstract

The invention discloses an automatic mesh grinding and collecting device of raw ore. The device comprises a box body, dust collectors fixedly connected with the ground are arranged at the front side,the rear side and the rear side of the box body, motors I which are fixedly connected with the ground are arranged at the front end and the rear end of the right side of the box body. The device andthe method have the beneficial effects that the structure is simple, the operation is simple and convenient, a crushing step is directly skipped for grinding, the cost is saved, can be used for carrying out multi-mesh grinding on the raw ore at one step, raw ore powder can be automatically collected in the grinding process, so that the condition that the raw ore can only grind a single specified mesh in the prior art is solved, the conditions of repeated feeding and discharging and changing grinding tools with different meshes are avoided, the whole process is automatic, simple, efficient, convenient and fast are achieved.

Description

technical field [0001] The invention relates to the technical field of ore dressing and grinding, in particular to an automatic sub-mesh grinding and collecting device for raw ore and a use method thereof. Background technique [0002] Mineral dressing is based on the physical and chemical properties of different minerals in the ore. After the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation and other methods are used to separate useful minerals from gangue minerals. Various symbiotic (associated) useful minerals are separated from each other as much as possible, and harmful impurities are removed or reduced to obtain the raw materials required for smelting or other industries. The ore dressing process is completed in the dressing plant, generally including the following three The most basic technological process, its sequence is preparation operation, its sorting operation, processing operation, and the preparation operation...

[0002] Mineral dressing is based on the physical and chemical properties of different minerals in the ore. After the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation and other methods are used to separate useful minerals from gangue minerals. Various symbiotic (associated) useful minerals are separated from each other as much as possible, and harmful impurities are removed or reduced to obtain the raw materials required for smelting or other industries. The ore dressing process is completed in the dressing plant, generally including the following three The most basic technological process, its sequence is preparation operation, its sorting operation, processing operation, and the preparation operation is divided into crushing, grinding, screening and grading, ore washing. The process of crushing ~1500mm ore blocks to a particle size of 5~25mm includes crushing, crushing, splitting, etc. Generally, it is carried out in three stages: coarse crushing, medium crushing, and fine crushing. Grinding is mainly based on grinding and impact , grind the crushed product to a particle size of 10-300 μm, the particle size of the grinding is determined according to the dissemination particle size of the useful minerals in the ore and the sorting method adopted, the energy consumption of the grinding operation is high, usually accounting for about half of the total energy consumption of mineral processing , the existing mined ores must be crushed before they can be ground, because the existing grinders such as ball mills can only grind small particles of ores, but this increases the purchase of equipment, processing, and energy consumption. and many other costs, and moving the crushed raw ore to the grinding equipment requires manual operation. In the grinding link, for different uses of the raw ore, it needs to be ground into different meshes for beneficiation. The existing equipment can only grind the raw ore Grinding into a single mesh is extremely unfriendly to the situation where the quantity of raw ore is small but the demand for mesh is too large. It is very inconvenient to need multiple feeding and discharging. At present, there is no direct crushing step for raw ore on the market. A fully automatic assembly line device that can grind and grind multiple meshes at a time
