If a small amount of coal remains in the mill after it is shut down, it slowly increases in temperature. If the pulverized coal undergoes spontaneous heating and the coal mill is restarted with hot embers present, an explosion or fire is possible.the advantages of ball and race mill are as follows: lower capital cost. lower electricity power consumption. lower workspace required. lower weight. however, in ball and race mill there is greater wear as compared to other coal pulverizers. the usage of pulverized coal as a fuel has now become the standard method of firing in many huge boilers.
