Friction In Cement Mill Grinding Media

Cement Mill- Ball Mill Dynamics

Cement Mill- Ball Mill Dynamics

The addition of a grinding aid in the mill causes dispersion of the ground material; i.e. it 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 balances state, thus reducing .
