Since the use of pulverized coal-fired boiler technology in the 1920s, coal mills have come out on request.

Pulverized coal is a machine that grinds pulverized coal into powder, and it is an important auxiliary equipment for boiler to burn pulverized coal. In the boiler unit of direct-fired pulverizing system, the pulverizing system connected with the boiler has actually formed a closely related whole. Therefore, with the progress of boiler technology, coal has also been properly developed.

The most important device of coal in the work is pulverizing equipment. In order to meet the needs of various boilers burning different coals and meet the requirements of combustion technology, there are also many types of pulverizing equipment of coal mills, but most types of coal mills in China were imported from abroad many years ago. With the development of industry, new requirements have been put forward for the types of coal mills in various industries. The design of MPF will improve the design of medium-speed coal mill. In the design process, three-dimensional design technology is fully utilized and new methods are adopted for design and analysis to meet the new requirements of rolling mill equipment in various industries.
