A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Increasing the stroke, the power and the retaining force while improving crusher body design and weight to withstand the force are principles of kinematics. A higher density in the crushing chamber improves the inter-particle crushing action, resulting in superior product shape, high reduction ratio and high capacity.

R: Size reduction ratio. The ratio of the gape width to the near side jaw opening. This ratio may vary from 1/3 to 1/9, but is generally 1/3 for primary crushers and 1/4 for secondary crushers. θ: Nip angle. One of the most important parameters is the angle between the two jaws, which is referred to as the nip angle. The nip angle is the angle

Not mentioned so far it the fact that because of the ‘no nipping angle restriction’ impactors and hammermills produce a much greater size reduction ratio. Impact crushers are commonly used to crush rocks with a silica contain under 5% such as coal, limestone, and phosphate. The only reason why you would use an impact mill/crusher or a hammer mill on a high-silica rock is because it might

3. Tertiary/Quaternary/Final Reduction Crushing. The goal of the tertiary (third), quaternary (fourth) or final reduction stage of the crushing process is to size and shape rock or other material into a marketable product. Again, there may be overlap between stages in terms of which crusher styles work best.
