Mar 28, 2020 How to solve the problem of spits in coal vertical mill 1. Theoretically speaking, if the wind speed of the nozzle ring of the coal vertical mill is sufficient, the mill will not discharge slag, it will only be full, and finally the vibration will stop. However, in actual production, the wind speed of the nozzle ring cannot be increased indefinitely, so slag discharge occurs.
Jun 03, 2014 In the grinding mill system of pulverized coal conveying gas, is due to the mixture of gas and coal dust, a spark will make the fire expand and produce greater pressure, resulting in coal dust explosion. So the mill model need to consider vertical mill explosion problem of coal grinding work.
