The ball mills are widely used in the thermal power plants,but most of them are running in the conservative conditions,with large power consumption and small contribution to the coal-milling system. One of the reasons is that there is still not a practical and accurate method to measure the coal storage(or mill load) of the mill.The traditional methods denoting mill load by stress difference
