High chromium section and low chromium section are widely used in the powder preparation and ultra-fine deep processing of cement building materials, metal mines, coal slurry thermal power, chemical engineering, ceramic coating, light industry paper making, magnetic materials and other industries.High chromium section compared with low grid section has low abrasion, good toughness and less crushing. In the process of use, the surface hardness will be further improved and the wear resistance will be enhanced. At the same time, the production capacity of the grinding machine can be improved, and the specific surface area of cement and the recovery rate of concentrate can be improved.With the rapid development of the national economy, the resource industries such as cement, metallurgy and mining are developing vigorously, and the steel segment application manufacturers are increasing day by day.The invention of high chromium section not only improves the grinding efficiency, reduces the time of stopping for ball filling and The Times of starting and stopping, but also extends the period of stock cleaning and reduces the labor intensity of workers.Especially in the cement mill second three cang and metallurgical concentrator second three section grinding ore use effect is more significant.
