The basalt is stable in performance and compressive, and also has wear-resistance, less water content and asphalt adhesion. Because it has many pores and is quite hard, mixing it in concrete can not only lighten the weight of concrete, but also is still very strong, and has the characteristics of sound insulation and heat insulation, so it is a good aggregate of lightweight concrete for high-rise buildings. And the basalt is a very good grinding material, then basalt fine grinding choose which kind of grinder is appropriate?

The hardness of basalt, which is hard and tough, has a high content of silicon and is difficult to deal with in actual crushing and grinding operations, should be considered first. Therefore, the choice of basalt grinder should be reasonable. At present, the main equipment used in basalt processing are Raymond grinder or high-pressure roller mill. The high-pressure suspended roller mill is a new type of equipment which is improved on the basis of ordinary Raymond mill. Compared with ordinary Raymond mill, this kind of mill has longer service life and is more suitable for basalt processing.

In general basalt grinding, when the material enters the grinding chamber, it is shoveled up by a spade and sent to the grinding roller and the grinding ring for rolling. After rolling, the powder is brought into the analyzer with the circulating air of the blower. The qualified fine powder enters the cyclone collector with the air flow, and the large particles fall back to the grinding machine. The recirculating air returns to the blower to repeat the above process and the remaining wind enters the bag filter to purify. And the output is large and the efficiency is good, so the powder produced by this mill is of high quality and fine and even.

At present, there are various types and types of basalt grinders on the market. There are two kinds of basalt grinders: Raymond grinder and high-pressure suspended roller grinder. As to which kind of high-pressure suspended roller mill is suitable for fine grinding, many factors should be considered comprehensively, according to the specific requirements of the manufacturer, grinding fineness and output, site conditions, investment plans and so on. Therefore, users can purchase basalt grinding equipment according to their actual production needs.
