Life of the Media

The media life is a critical parameter.

You must ensure that you can use the selected media size for many years without any breakage or deformation.

If you go with the smaller media, then life will be less.

The smaller media is more prone to breakage than the larger one.

So, choose wisely.

Size of the part

The size of the material needs to be considered first.

The media must be able to reach all the area in the part for an efficient grinding process.

If the part has holes or crevices, then ensure that the media does not get stuck in these holes.

Here, a small size media will be more useful as it can reach more surface area for grinding.

It will help to increase the grinding efficiency of the process.

If you still find it hard to select the right media size, then check with our engineers.

They will help you to select the right size based on your milling requirements.
