Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
There are two types of crushing, compression or impact. Jaw crushers and cone crushers use a compression force while impactors and hammermills use an impact force. A jaw crusher is used in a wide variety of applications, including construction and recycling demolition, quarrying and mining, asphalt production, etc.

Over 1,000 tph, select a gyratory crusher. Between these capacities, you have a choice. Source: Chris Ottergren For a hard rock mine …
Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
In most crushing installations a jaw crusher takes care of primary crushing. Plants with very high capacities that are common in mining and less popular in aggregates production, normally use a primary gyratory crusher. When the processed material is easy to crush and not very abrasive, an impact crusher may be the best choice for primary ...
For instance, a hard material like granite or basalt may require crushers with compressive forces that can produce high crushing strengths, like a jaw crusher or a cone crusher. As an example, the limestone and coal can be processed using impact crushers or roll crushers. Abrasive materials lead to very severe abrasion of crushing surfaces, …

As an indirect jaw crushing parameter, the choke feeding intensity was also emphasized by Beloglazov and Ikonnikov [40]. As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41], the production of fines can be diminished by regulating the mf in the crushing chamber.

Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other reciprocates. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly used …
Measurement of the electricity consumption during crushing was done on a laboratory jaw crusher Bauknecht, Fig. 1. Jaw crusher operates by compressing the feed material between a fixed and a moving jaw back and forth in an eccentric cyclic motion (Cleary and Sinnott, 2015). The feed size of the opening was 110 × 100 mm 2.
