Ensure that the milling chamber is neat and clean before loading the slurry and the media into it.

The out pipes must be checked for blocks if any.

The media can be pre-grinded inside the chamber with appropriate solvent and resin.

The time for pre-grinding will depend on the viscosity of the slurry.

For a low viscos slurry, you can lower the pre-grinding time.

If the viscosity is high, then increase the pre grinding time.

Rotational speed is another parameter that plays a critical role in grinding process.

Rotational speed must be set according to your grinding requirements.

The slurry viscosity must match with the rotational speed of the chamber.

Higher the slurry viscosity, higher will be the rotational speed and vice-versa.

The ratio of the material to the beads must be in the recommended range.

The rotational speed will vary for wet grinding and dry grinding process.

You can run the machine at lower speeds for a dry grinding process.

Once the process is complete, the media needs to be separated from the material.

The separated media must be washed and cleaned before storing.

Visually inspect the media.

If there are any damaged beads, you can remove it before storing.

The breakage will be more in the case of smaller beads.

The time duration of the grinding process will vary for different parts and applications.
