Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.

Jaw crushers have proven to be a workhorse in the aggregates industry and are machines that reduce the top size but do not create fines or cubical particles to the same extent as, for example, a cone crusher. Jaw crushers are mainly used in operations where the volumes involved do not justify a gyratory crusher.

The size of the product depends on the crusher set, the distance between the rolls. Due to single pass operation, it is evident that no middlings or over-size is produced. The normal speed of operation of commercial light duty rolls is 130–300 rpm compared to heavy duty rolls whose operating speeds are in the region of 80–100 rpm.
