A single type of crusher is not sufficient enough to convert the large size rock into required size stone. So, the crushing process involves primary, secondary and tertiary crushers during the whole crushing cycle to achieve the required dimension. Figure 1 shows different stages of crushing which have been discussed earlier. In these stages ...

The right one for primary crushing often depends on the material to be crushed, but the reduction ratio of jaw crushers are usually between 8:1 and 6:1. Secondary Crusher. These crushers break down materials into smaller sizes and often have a reduction ratio less than 3:1 in crushing. A secondary impactor, hammermill, and cone crusher are ...

These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other. Horizontal …

The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size. The output of the primary crusher is fed to a secondary crusher, which further reduces the size of the material. Similarly the output of secondary crusher is fed to the tertiary crusher which reduces the material size ...

After the material is extracted from a mine, the primary crusher ensures the rock is broken down into a size the secondary crusher can handle.
