Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but

Understanding Comminution: Compression versus impact crushing
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 ...

Production and Uses of Crushed Rock Aggregates: An Overview
In general, aggregates should be hard and tough enough to resist crushing, degradation and disintegration from any associated activities. About 52% of all construction aggregate is crushed stone, while 48% of the remaining is sand and gravel (AASHTO, 2001). A mineral aggregate is used to denote a rock product as aggregate.
