It is crucial to design and manufacture crushing plants with appropriately sized and staged equipment.

Impact crushers are used mainly for less abrasive materials as primary and secondary crushers.

and the geology of the host rock is relevant right from the blasting stages of aggregate production. This tends to affect the size of the material that will report to the crushers, and hence will determine the size of the jaw crusher required at primary stage.

“The hardness of the material will also affect the primary crusher selection and may well impact the throughput that can be achieved through the crushing circuit. Silica levels and other abrasiveness factors will influence wear levels, so operators need to

be aware that maintenance interventions may be more frequent under these conditions,” concludes Van Rensburg. Look out for Part 2 of this article in the September edition of Capital Equipment News. b
