The micro powder grinder is mainly used in the fields of metallurgy, building materials, coal mines equipment for sale chemical, mining minerals such as grinding materials processing. With the development of industry, the requirements are increasingly high for raw materials, ball mill, in some cases can no longer meet the needs. This paper describes the need to pay attention to the daily use of the micro powder grinder, to ensure the stability of the machine running, to avoid losses to the enterprise. 1.
