Bentonite ultrafine mill accessories grinding roller and disc liner material generally use high-chromium cast iron or nickel-chromium alloy, but this material often breaks, the damage is quite serious, especially the loss of production, it is impossible to estimate.

The influence of the hardness and fracture of the bentonite ultrafine mill raw materials, the heat treatment and fracture of the accessories after the processing of the raw materials, and the friction and fracture of the bentonite ultrafine mill accessories. In view of the above situation, it is recommended to make the following solutions.

Everyone knows that the harder the product is, the more wearable it is. Therefore, it is very simple to make a more wear-resistant grinding roller and grinding disc, because you only have to try to improve its hardness. Many foundries flank the castings with a chromium content of 30. %, HRC hardness reached 63-65, but in fact it is not the case.
