Different from steel balls, the rotation flexibility of the Grinding Cylpebs during the grinding process is between the spherical shape and the rod shape, mainly relying on line contact to crush minerals. When the steel section is used as the medium grinding, the products of each particle size are relatively uniform, and the grinding of the intermediate product has a certain selectivity, and has a certain protective effect on the minerals, giving full play to the advantages of the rod mill, but the crushing force is not as good as the spherical one. ;Steel ball grinding is ground through point contact with the material, suitable for fine grinding, the effect is good, but it does not have a protective effect on the material, it is easy to cause over-grinding, and the yield of each particle size of steel ball grinding does not change The steel section is uniform. Therefore, in order to ensure the grinding fineness and make the particle size distribution even, many mines will use the mixed addition method of adding steel balls and steel segments at the same time when adding grinding media to obtain a good grinding effect.
At present, the steel section on the market has casting process, forging process, and direct shear forming process. The characteristics of the casting process itself make the product structure not dense enough, and in order to facilitate the removal of the mold, they are all tapered steel segments. The forging process maintains the compactness of raw materials in organization, but often results in S-shaped segments, which affects linear contact and is not conducive to comprehensive and efficient grinding. The sheared horseshoe will also affect the running track of the steel section and the grinding contact surface, reducing the grinding efficiency.
Through long-term painstaking research, Goldpro New Materials Co., Ltd. has integrated the advantages of the above-mentioned processes and successfully developed a high-efficiency rolling process and a complete set of equipment, so that the rolled steel section is in the shape of a capsule, and there are steel balls at both ends of the grinding effect. and the straight-line contact effect of the segment body is good, the running track is stable during the grinding process, and the comprehensive grinding efficiency is high and the effect is good. In order to further improve the use effect of customers, our company has continuously developed special materials for steel sections and supporting heat treatment processes, and has formed a series of steel section products with multiple specifications and materials, such as 20mmX30mm ... 70mmX80mm and other steel sections. It is also possible to order various different types of steel sections according to the mine working conditions and customer requirements, which has met the needs of grinding.
