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.

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
The term "primary crusher," by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant.
