The raw coal is stored in the raw coal bunker and fed into the vertical mill by the belt weigher in bottom of raw coal bunker. After drying, grinding and powder classifying, the coarse coal powder with unqualified size will be fall down onto the millstone again for grinding.
From the bunker of powder preparing unit, using the weight belt feeder, coal enters the roller mill. The weight of coal supplied to the bunker is measured by electronic weighing system, and the volume is controlled by sensors of top and bottom levels. The coal stock in the bunker allows the mill to work in continuous mode for 45 hours.

However, the mill could still operate under those occasions. A third factor which sometimes influenced the grinding capacity negatively was the particle size of the raw coal. Too fine coal, and the absence of bigger coal particles, prevented the buildup of a sufficiently high coal bed on the grinding table.
If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the inrushing 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.
