Which type of coal mill is needed to turn lumps of coal into pulverized coal

Thermal power plants are further divided into coal-fired power plants and gas-fired power plants. Coal-fired power plants need to process lump coal into pulverized coal first in order to improve the efficiency of coal combustion. Which type of coal mill is used to turn lump coal into pulverized coal? Coal mill, as the name suggests, is a coal grinder, which is a device that crushes coal and then grinds it into powder. Its working purpose is to promote the full combustion of coal pulverizer.

Which kind of coal mill is used to change coal lumps into coal powder? There are many types of coal mills, which can be categorized into three types according to the rotational speed, i.e., low-speed coal mill (rotational speed 15-25r/min), medium-speed coal mill (rotational speed 40-300r/min), and high-speed coal mill (rotational speed 500-1500r/min). Low-speed coal mills, such as ball mills, grind coal by the principles of impact, extrusion and grinding, medium-speed mills mainly grind coal by the principle of crushing, and high-speed mills, such as fan mills, grind coal by the principle of impact.

With the progress and development of science and technology, medium-speed coal mill is constantly upgraded and optimized, such as European version of the mill, high-pressure suspension mill, vertical mill, etc., set crushing, grinding, classification and powder collection in one, compact structure, small footprint, power consumption, low noise, intelligent safety, clean and environmentally friendly, etc., the comprehensive advantages of a significant, broad application market.
