The addition of a grinding aid spreads the feed particles farther apart, thus exposing more surface area to the grinding media, resulting in increased production. The grinding aid adheres to the individual particles, thereby restoring the particles to a balanced state, thus reducing agglomeration, ball coating and pack set.
