Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size.

Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Crushing is accomplished by compression of the ore against rigid surfaces or by impact against surfaces in a rigidly constrained motion path. Crushing is the first mechanical stage in the process of comminution. Stages of crushing: Primary crushing → Run-of-mine ore (ROM) reduced to 10-20 cm (4"-8"), ( " = inch = 2.54 cm)

Primary crushers should provide a significant crushing ratio that’s good enough to impact how many more downstream comminution units are required. No crusher, when set at any given discharge opening, will make a product all of which will pass a screen opening of the same dimensions as the given discharge opening.

In practice, many jaw crushers are not fed to their design capacity; this is because the subsequent processing plant does not have sufficient capacity to handle the volume of material that would be produced if the jaw crusher were working to capacity. Crushing setting: Efficiency. Ideally, the reduction ratio of a jaw crusher should be 6:1.
