PQ of cone mill machine

A new cone mill machine (for tablet granulation process) is purchased to substitute the oscillating granulator in our company.

I would like to know what validation activities shall be performed during the PQ on this new machine.

Our preliminary proposal is to perform PV (with consecutive 3 batches) of a product to prove that the outcome products (i.e. the intermediate products and the bulk tablets) maintain our predefined requirement.

Is it appropriate? Any recommendation & comment?
