Raw material of various sizes are brought to the primary crusher by rear-dump haul units, or carried by a wheel front-end loader. Primary crushing reduces excavated rock to a more manageable size. There are different types of primary secondary and tertiary crushers including jaw crushers, gyratory crushers, impact crushers, and autogenous crushers.

2020-3-19 The graph displays a trend that favours the modified section of the trial blast. An average crusher throughput of 191 tonnes per hour was calculated from the reference section of the blast and 234 tph calculated from the modified end. This equates to an 18.3 per cent improvement in primary crusher throughput for the modified section.

The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation. Primary crushing with
