— The cone crusher is a popular rock crusher in mining operations, aggregate production, and recycling applications. Many users use it for size reduction and shaping of precious metals (e.g. gold, silver, and palladium), concrete, and hard rock.
— 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.
— The impact device more nearly approaches actual crusher operation, both in velocity of impact and in the fact that broken stone is used in testing. The average impact crushing strength is an indication of the energy required for crushing, while the maximum compression values indicate the danger of crusher breakage and the type of construction ...
As the feed moves towards the drive end of the cone crusher, its size decreases (due to the crushing action), and ever smaller pieces move towards the drive end of the crusher. After passing through the crusher, the product -now at a much-reduced size- is discharged through an opening in the bottom shell. Gyratory Crusher Operation
The operation of a plastic crusher involves holding the feed material between two solid surfaces and applying sufficient force to fracture or deform the material (source: GlobalSpec). Crushers made of thickened …
