Description

A kind of raw ore automatic sorting grinding and collecting device and using method

technical field

The invention relates to the technical field of beneficiation and grinding, in particular to an automatic sorting, grinding and collecting device for raw ore and a method for using the same.

Background technique

Ore beneficiation 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, electrical separation and other methods are used to separate useful minerals from gangue minerals, and make Various symbiotic (associated) useful minerals are separated from each other as much as possible, and harmful impurities are removed or reduced to obtain raw materials for smelting or other industries. It is the most basic technological process, and its sequence is preparation operation, its sorting operation, and processing operation. The preparation operation is further divided into crushing, grinding, screening and grading, and ore washing. Among them, crushing is to mine the particle size of 500. The process of crushing ore blocks of ~1500mm to a particle size of 5 ~ 25mm. The methods include crushing, crushing, splitting, etc. Generally, it is carried out in three stages of coarse crushing, medium crushing and fine crushing. Grinding is mainly grinding and impacting. , 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 used. The grinding operation consumes high energy, usually accounting for about half of the total energy consumption of beneficiation , 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 ore, but this increases equipment purchase, processing, energy consumption and many other costs, and moving the crushed raw ore to the grinding equipment requires manual operation. In the grinding process, the raw ore needs to be ground into different meshes for different purposes for beneficiation. The existing equipment can only grind the raw ore. Grinding to a single mesh is extremely unfriendly to the situation where the number of raw ore is small but the demand is too large, and it is very inconvenient to need multiple feeding and discharging.
