Several properties of ball mill grinding

　　Several properties of the ball mill mill

　　1, dissociated milling. The purpose of such grinding is mainly to achieve sufficient monomer dissociation between useful minerals and veneer minerals in the ore and useful minerals, and meet the requirements of subsequent operations on the particle size. A moored metal mine and non-metallic mineral choice before such grinding, Wet mortallurgical leaching before the mine, etc. Suitable monomer dissociation between useful minerals and pulse minerals and useful minerals is a prerequisite for mineral sorting, and various mineralization methods are limited by granularity, and thus make useful minerals and pulse minerals and useful minerals The monomer dissociation, and in the granularity, the demolition requirements are the basic requirements of the pre-mineral mill. Wet metallurgical immersion wear must be fully dissociated and exposed to the mineral to be leached, so that it has a chance to contact the leaching agent, while the requirements can be worn to increase the leaching speed. The dissociated grinder is prepared in the process, but the quality of the massage of the mill is greatly affected by the technical and economic indicators of subsequent operations. The dissociated grinding has an extremely important position in modern mineral projects, and the minerals it treats is also the most.

　　2, comminuted milling. Such milling is the purpose of pulverizing the mine, and even the smaller is better. If the cement clinker is solemn, the higher the hydration speed of the cement, the higher the quality. The heavy wear and better grinding machine is also required in the grinding machine of the thermal power plant, and the more pulverized coal is injected into the combustion chamber. The grinding of pesticides and certain chemical raw materials is also such milling. Crushed mill is often the final operation of mineral processing, which is the final product of mineral processing. The amount of mineral treated in such milling is also very large, second only to the dissociation grinding.

　　3, rubbing gear mill. The purpose of such grinding is neither dissocated with minerals, nor a pulverized ore, but in order to expose the mineral particles to the fresh surface to facilitate bonding and good bonding quality. Wetting grinding in the murries of the construction sand mold, the moisturizing grinding in the metallurgical ball formation process, etc. In such murries, excessive grinding is harmful, and the resulting mine will affect product quality, and excessive blows of ore sand also reduces product strength. Therefore, fully exposing fresh surfaces of mineral particles and minimizes the basic requirements of this type of grinding. Such milling is also prepared for work, and the quality of hemp mineral products seriously affects the quality of product in subsequent operations.

　　4, ultra-fine shred. In the previous type of grinding, the product particle size is relatively ratioMore crude, the particle size of the rubber grinding mill is thick. The limitation of the fractional particle size of the dissociationless mill is not very fine, even if the fine mill and ultrafine product, the particle size is also 10 ~ 20 um or more. It is comminuted mill, and its product particle size is also a few microns. Professor Finnish Hu Ji proposes that the granularity range of the mill is 20 ~ 0.001mm, that is, as a limit of 1 um as the mill, this is referred to as "ordinary grinding" range. The so-called ultra-fine pulverization is that the product particle size is more thin, and the product particle size is several microns, even below micron level, exceeding the "common grinding" range of the op yard.
