Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to a grinding device for ore processing. Background Art

[0002] There are very few single mineral rocks and ores with important economic value in nature. Even single mineral rocks contain various impurities. Not all properties of minerals can be utilized. The mineral processing process has four stages: crushing, grinding, beneficiation, purification; ultrafine grinding; surface modification. Crushing and grinding are operations to reduce the particle size of mineral raw materials. Reducing to 5mm is called crushing, and finer grinding operations are called grinding. The fineness of grinding should be determined based on the results of process mineralogy research and experiments on the ore. Its purpose is to achieve monomer dissociation of useful minerals and gangue minerals in the ore, to provide materials of suitable particle size and form for subsequent beneficiation operations, or to provide materials of suitable particle size for subsequent ultrafine grinding, or to directly provide general powder products.

[0003] At present, in the commonly used ore processing and grinding equipment, crushing and grinding need to be performed in steps. In order to reduce the particle size of the ore to a grindable size, the crushed ore usually needs to be further crushed and screened before grinding, and then the screened ore particles with small particle size are added to the grinder for grinding. There are many operating steps and the operation is complicated, which affects the processing efficiency during processing. For this reason, we propose a grinding equipment for ore processing.
