A cone crusher punishes itself in every minute of operation. It squeezes a dense mass between heavy castings until the mass disintegrates. It abrades and minces aggregate until the material yields to the applied forces. It rumbles and vibrates and bangs as its core shaft spins eccentrically to capture and reduce chunks of aggregate.
Cone crushers are used in the aggregates and mining industries to crush rock material. The pressure on cone crusher liners is the key factor that influences the hydraulic pressure, power draw and ...

Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel, depending on the character of the material to be crushed and the particular class of service for which the machine is intended. Standard crushers, in the small and medium sizes, are customarily fitted with chilled-iron head and concaves for …
The working principle of a Cone Crusher is similar to that of a Gyratory Crusher, however, it is usually in use for secondary and tertiary crushing of granite, basalt, gneiss and other hard rock, as well as in the mining and cement industries. Such as a Jaw Crusher it works on the basis of compression and squeezes the material until it breaks ...

This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. ... As the smallest distance between the concave and the mantle, the CSS is the final crushing zone, and is vital for determining the product size, as well as energy consumption and crusher capacity. Know your feed.
The distance a particle falls during a stroke is called a crushing zone. The amount of material that enters the inlet zone, i.e. the first crushing zone, determines the capacity of the crusher. During operation at normal eccentric speeds the material does not entirely fill the inlet zone due to dynamic and boundary effects.
