The broken shale is then loaded into offroad dump trucks for transportation out of the quarry to the primary crushing operation. Primary Crushing and Screening. The material that arrives from the quarry is dumped directly into a rock box and then fed through a vibrating grizzly feeder and into the primary jaw crusher.

In inpit crushing, the primary function of a crusher is to provide a smaller uniform product size for each of transport by the conveying system. Minimum power consumption in part of a good design. For their coarse duty, primary crushers use, comparatively lower energy, to other systems.

aggregates and recycled aggregates. Primary aggregates are produced from naturally occurring mineral deposits, extracted specifically for use as aggregates and used for the first time. Most construction aggregates are produced from hard, strong rock formations by crushing to produce crushed rock aggregates or from

which can predict plant crushing behaviour in primary crushers. Data generated from this may allow operators to gain better control of the plant, reducing the generation of minus 4 mm material.

Crushing in an impact crusher takes place when the stone is struck by the spinning impact bars, and by that stone being flung against an apron. When impact crushing is used, the striking of the aggregate by the spinning rotor's blow bars knocks off or breaks the elongated fractures. This process is repeated by an impactor in the secondary stage.

The supplier says the ERC redefines the concept of primary crushing hard rock. As such, it is suited not only for use in underground operations but also in open pit mines and quarries, where its qualities are particularly useful in semi or fully mobile operations. For decades, gyratory and jaw crushers have proved their worth in crushing hard rock.
