Poor fragmentation will increase the load to secondary and tertiary crushing stages, if used, because there will be less undersize that can be split off to bypass these stages. This will affect productivity and energy consumption. It is highly probable that the blasted size distribution introduced to the primary crusher will affect the feed size distributions throughout the crushing stages.

Investigating the effects of feeding properties on rock

May 01, 2021· 1. Introduction. Rock crushing is the first mechanical comminution process after drilling and blasting operations in rock fragmentation. The energy required for comminution depends on the physicomechanical properties of the rocks and the quantity of materials being crushed .Although the use of different crushers should be placed in a definite order, the efficiency of crushers may be improved

The Concept of crusher modeling Minerallurgy

The fragmentation of the material is modelled as several repeated crusher steps, and each step describes by a selection function and a breakage function, similar to the JKmodel. The selection function gives the probability that a single particle will be broken, when several particles are compressed.

Cone Crusher an overview ScienceDirect Topics

Cone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.

revolves around blast-induced fragmentation as the final deliverable of the mine to the crusher, while the crusher product is the initial input for the mill. Such a distinction defines the crusher as the link between the mine and the mill. It also signifies the necessity to assess the downstream effects in a stepwise manner
