Understanding Comminution: Compression versus impact crushing | Agg-Net
Compared with compression crushing, impact crushing will create more fines within the circuit, which will cause greater wear if processing abrasive material. This is why rocks with lower silica content are more suited to reduction by impact crushers. When compared with cone crushers, impact crushers often have a lower capital cost, but can

What is Impact Strength?
Impact strength – also called impact toughness – is the amount of energy that a material can withstand when the said load is suddenly applied to it. It may also be defined as the threshold of force per unit area before the material undergoes fracture [1]. The strength of materials may be defined in many ways, and some of the most common
