Dropped charge, also known as frozen or locked charge, occurs when solidified material inside a horizontal grinding mill does not cascade when the mill starts rotating at start up.Instead, it is lifted and then free falls onto the mill shell.Dropped charges experienced in large ball mills can be heard and felt hundreds of meters away and can be confused with an explosion or earthquake on.

The operating principle of the ball mill consists of following steps.In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media.The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
