Precautions when loading steel balls in ball mill

Ball mill loading steel ball size must be based on the physical and mechanical properties of the ore and ore particle size to determine, can not be added at random, if you add the steel ball size is not appropriate, will seriously affect the grinding efficiency, often encountered in two cases.

1. When the material particle size or hardness is large, the proportion of large balls added less then there will be grinding products run coarse phenomenon, can not meet the fineness requirements, while the handling capacity will be limited, affecting the grinding efficiency.

2. When dealing with smaller ore size and lower hardness of the material, if the proportion of small balls to add less will also appear in the product strength of the phenomenon of coarse. At this time it should be appropriate to add small balls to increase the proportion of small balls, to adapt to the nature of the ore to be processed, in order to obtain a better product fineness.

In addition to the ball mill steel ball size to be loaded in accordance with the proportion, but also need to know how to determine the proportion of steel ball size loading.

In the treatment of hardness of coarse size of the ore, the need to have a greater impact, the need to load the size of the larger steel balls; in the treatment of softer ore to give smaller particle size, the requirements of the product size is finer, it should be grinding-based, can be loaded into the size of the smaller steel balls.

Many production sites of the ball mill, generally will be loaded with a variety of ball diameter steel balls, according to a certain proportion of the ratio to deal with different sizes of ore particles composed of materials.
