Coal grinding powder spraying machine, boiler special coal spraying machine, pulverized coal burner, inclined iron_Hebei Botou Shunda Machinery

The coal grinding mechanism of the coal grinding pulverizer
is that raw coal enters the grinding area of the grinding roller and the grinding disc, and is ground into pulverized coal under the rolling grinding of the grinding roller. Therefore, the loading force of the grinding roller is an important parameter for the safe and economical operation of the coal mill. As the loading force of the grinding roller increases, the grinding pressure of the grinding roller increases, the pulverized coal becomes finer, the coal grinding output increases, and the characteristic coefficient of the pulverized coal particles becomes Large, the coal grinding unit consumption is reduced, but the vibration of the coal mill equipment is intensified, the wear is too fast, and the service life of the grinding parts is reduced.
