One of the most important things to consider when purchasing and using a ball mill for industrial applications would have to be the composition of the grinding medium. This is because apart from the size, nature of the material, as well as the density, the composition of grinding medium is one which is of great importance when using the grinding medium for manufacturing, given that its influence is one which is indeed, great. Below are the specific aspects of composition that you have to look out for when picking the grinding medium of choice for your ball mill.
The color of the finished product may or may not be important. In the case of the latter, you have to consider the color of the grinding medium you are using. This is because some materials to be grinded would be able to pick up the color of the grinding medium if it is used. The safest best would be stainless steel metals, in this case.
As with color, some materials to be grinded should also not be contaminated by the grinding medium, which is why you have to consider it. Using steel could cause steel dust to accumulate on the layer being ground. To be as safe as possible, it is best to use a medium of the same material as the one which is being ground.
If you’re looking to use the ball mill for flammable materials, make it a point to not use steel products, as this may spark and thus, cause a flame. In cases when the material to be ground is flammable, make sure to use either lead or ceramic ones, and if possible, wet-grinding and other materials deemed non-sparking, or those which are non-reactive to the material.
