The Determination of the Optimum Loading for Ball Mill

The Determination of the Optimum Loading for Ball Mill

When designing ball mill, it is necessary to choose suitable anti-abrasion materials and determine the suitable loading of grinding balls when starting and the refilled loading of grinding balls during the operation, which has significant practical meaning to the reduction of metal consumption and improvement of economic benefits. Then how can the mining machinery manufacturing companies determine the optimum loading for the ball mill?

The experiment shows that the consumption power of ball mill on the condition of with materials in it and without materials in it is only 5~8% of difference, which means that a large part of the power used for grinding the coal is consumed on the grinding balls and the movement of the cylinder. As for a ball mill, the energy consumed by the movement of the cylinder is certain, for this reason, reasonably determining the optimum loading of the grinding balls is crucial for reducing the electricity consumption.

The loading of the grinding balls of the ball mill is reflected by the full coefficient. When the loading of the grinding balls increases, then the force needed by the ball mill will also increase. When the grinding ball loading exceeds a certain amount, the force needed by the ball mil will slowly increase, but the electricity consumption of the powder grinding system will increase significantly. For this reason, the grinding balls loading should be appropriate because it is related to both the electricity consumption of the powder grinding system and the force needed by the ball mill.
