The working principle of primary crushers varies depending on the type of crusher, but generally, they work by reducing the size of the material through compression or impact. In jaw crushers, the material is fed into the crushing chamber and is crushed between a fixed jaw and a movable jaw. Gyratory crushers work by crushing materials …

The capacity is similar to that of a jaw crusher with the same gape, and breadth 'B' equal to the perimeter of the gyratory crusher. Since all the coarse crushers have greater capacities than the devices for the finer ranges of size reduction, a gyratory crusher of sufficient size to crush the required size feed may have an excessive capacity.

Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged ...

The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation. The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate.

Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with the feed. The initial impact is responsible for more than 60% of the crushing action, with the remainder being made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.
