Crushing and grinding at mineral processing operations include a wide range of different types of equipment and processes. On the crushing side, primary crushers are typically jaw crushers, but may sometimes include gyratory and/or cone crushers. These crushers use compressive forces to break the ore and do not normally generate large volumes ...
