· 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.

A jaw crusher primarily consists of two plates: the fixed jaw plate and the movable jaw plate. The key to its operation is the reciprocating movement of the movable jaw plate, reminiscent of our very own jaw’s motion when we chew. This physical process exerts sufficient force on the input material, often large chunks of rock or ore, causing
