In some cases, ball milling is used before HPGR when the pellet feed is too coarse or too hard for saving grinding costs and improving balling characteristics of the pellet feed. For example, a wet ball mill plus an HPGR circuit was installed in WISCO Minerals' pellet plant in China to pretreat Brazilian specularite concentrates.

One potential method is strengthening the internal and external ventilation of the grinder. Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature.
