Grinding Aid usage


A question about grinding aid usage. The Cement plant in which i work both have open and close circuit mills. The type of grinding aid used is HEA2. The target use is 0.02% - 0.05% of the feed.

My question is, should there be a difference in percentage due to running open circuit to close circuit.
