The working principle of the autogenous mill is almost the same as that of the ball mill. The difference is that the barrel body of the autogenous mill is larger, which does not use steel balls or any other grinding medium. The efficient autogenous mill uses the crushed material in the barrel body as the grinding medium, which continuously impacts and grinding to achieve the purpose of grinding.
Sometimes, in order to improve the processing capacity of the autogenous mill, a small number of steel balls can be appropriately added, usually accounting for 2-3% of the effective volume of the autogenous mill (also known as a semi-autogenous mill).
