Ball Mill Charge

Dropped charge also known as froen or locked charge occurs when solidified material inside a horiontal 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
