Multi-objective planning of cone crusher chamber, output and size reduction
The speed of the eccentric main shaft is an important factor affecting cone crusher chamber geometry, output and size reduction. Lower speeds allow the rock to slide in the chamber (as shown in Fig. 4) and reduce crusher output. However, excessive speed can inhibit rock fall, seriously affecting output.

Reduction Ratios in Crushing
Reduction ratio - 10:1. Impact Crushers can be used for either primary or secondary crushing and work by creating a sudden impact force that shatters the material into smaller pieces. They often come as primary crushers (with an 8:1 crushing reduction ratio) or secondary crushers (10:1 reduction ratios) and are perfect for crushing medium-hard ...

Output prediction of cone crushers
Jaw, cone and gyratory crushers all utilize form conditioned ncompression to achieve size reduction. In this type of process energy is a secondary, but important parameter. For this reason geometry controlled (form conditioned) compression crushing tests are used to achieve the breakage characteristics of the rock material [2].

Gyratory Crusher
The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.
