principals of a cone crusher
Cone crusher modelling and simulation using DEM
Cone crusher theory. The functional principle of a cone crusher is to compress particles between two surfaces. Particles can be subjected to two different modes of compressive breakage; single particle breakage (SPB) and inter-particle breakage (IPB). The particle bed in the inter-particle breakage mode can either be confined or unconfined.

CONE CRUSHER. Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in secondary, tertiary and quaternary stages.

Gyradisk Cone Crusher. For finer size products (e.g., -6 mm), a special cone crusher known as the Gyradisc is commonly used. Operation is similar to the Standard Cone Head; however, breakage is mostly by attrition rather than impact. Reduction ratio is around 8:1. Feed size is limited to less than 50 mm with a nip angle between 25 ° and 30 °.

Gyratory Crusher
The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the …
