In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in highthroughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault diagnosis in the crushers lags behind. Therefore, it is ...

Best suited for secondary crushing applications, cone crushers are designed to crush presized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

Semi mobile crushers are still operated at the mining face but are not moved as often as the mobile crusher.. A movable crusher is positioned in the mine's center at the same mining level as it working face. Such a crusher is mobilized every couple of years to keep it economically close to the core mining operation. Highland Valley Copper is a good example of large movable crushers (2) and ...

Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in largescale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.

The coal crusher generates large vibrations when crushing coal blocks, which can affect the equipment itself, as well as the safety of the structure. In order to study the dynamic characteristics of coal crusher, a finite element model of the coal crusher chamber in the Shangluo power plant was built by using ABAQUS. Firstly, modal and harmonic response analyses were conducted, and the ...
