Even wear in the crushing cavity avoids localized restriction of the feed opening, maintains a uniform crusher setting, and achieves consistent size reduction. The hydraulic motor and gear drive adjustment provides finer control of the setting: the setting can be easily adjusted under load to compensate for liner wear without turning off the feed.
