Measures of using cast steel grits to grind fine ore

2020-03-26 09:25:23   Review:0 Click:
  Some cement manufacturers and thermal power plants, especially some iron ore and non-ferrous metal mining areas, usually use cast steel grits and forged cast steel grits as grinding materials, which are widely used.

  Although some cast steel grits manufacturers use high chromium cast steel grits to replace low chromium G80 Cast Steel Grits and forging cast steel grits, but because the quality of their products is not good enough, there is no good wear resistance, sometimes even a large number of broken cases, which can not bring economic benefits to users, so it has not been able to change the status quo. The grinding effect of the material mainly depends on the particle size of the cast steel grits, which is mainly based on the large proportion of the material, i.e. the representative particle size. In practical application, the secondary ball diameter in multi-stage cast steel grits distribution can also be used as the standard. The ball loading system mainly includes the density, hardness and wear resistance of cast steel grits.

  In general, the impact force of large density and diameter cast steel grits is large when they fall, and the hardness of cast steel grits is also large. Therefore, for the hard and coarse ore, the cast steel grits with large density and diameter are more needed.
