Read OnIf the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.
Read OnCoal mill. The vertical coal mill is used for the grinding of coal raw materials. The coal raw materials go down to the center of the grinding disc, and the coal raw materials are distributed and flattened out evenly by the centrifugal action of the grinding disc to form a material bed with a certain thickness. The crushing of a grinding roller ...
