Description

technical field [0001] The invention relates to the technical field of coal pulverizers, in particular to a coal pulverizer for a thermal power plant with a dust-proof function. Background technique [0002] The existing coal mills are difficult to control the size of the pulverized coal, which leads to the uneven size of the pulverized coal. The existing pulverizers basically grind the pulverized coal at one time, resulting in a poor effect of the pulverized coal. . Moreover, the usually used coal mills have high requirements for temperature and oxygen content. If the temperature of the coal mill is too high, the pulverized coal will burn and cause a fire, and the pulverized coal dust will float around and affect the environment, which is harmful to the work. People's bodies are affected. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of large amount of dust and high temperature in the prior art, and propose a coal p...
