Types of Crushers Explained: Everything You Need to Know
Shear Crushing: Shear crushing takes a shearing force and applies it to the material, which results in the formation of cracks on the weak planes. This method is not frequently used in rock crushing applications but can be found in some specialized equipment, like roll crushers, for example, for softer materials like coal or clay.
Modeling and Improving the Efficiency of Crushing Equipment
Therefore, the more completely the minerals are exposed during crushing, the better and more successful the subsequent beneficiation of the mineral is. The crushing stage cannot be avoided and therefore improving crushing efficiency is an urgent industry concern. A significant drawback of crushing units is their low energy efficiency.
Crusher Reduction Ratio
For a given ratio-of-reduction, the type of crusher with a flared crushing chamber will usually deliver a cleaner product than any of the older types; conversely, more reduction can be performed in the machine without creating excessive fines. The facts outlined in the foregoing paragraph have an important bearing on crushing plant design.
