jan 04, 2014 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.
when used underground, jaw crushers are commonly used in open circuit. this is followed by further size reduction in crushers located on the surface. when the run of mine product is conveyed directly from the mine to the crusher, the feed to the primary crusher passes under a magnet to remove tramp steel collected during the mining operation.
the crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper, and the associated infrastructure therein. minimizing the need for high cost stationary grids to control topsize underground was a requisite, and the topsize acceptance was met with the UG design.

sep 22, 2014 scalping is recommended for a jaw crusher for three main reasons: capacity increases when material below the crusher setting bypasses the crusher; also the energy consumption is lower. the life of wear parts increases; a jaw crusher usually wears more manganese steel per crushed ton than a gyratory crusher.
