Crusher - Wikipedia

OverviewBackground historyIndustrial useTypes of crushersTechnologySee alsoExternal links

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantagethrough a material made of molecules that bond together more stron

Crushing Products Size and Shape -What to Expect

The Fairmount crusher is inherently a somewhat cleaner breaking machine than either the standard gyratory or standard jaw types, but the class of rock for which the former crusher is largely used is usually subject to greater than average degradation during the blasting and loading operations in the quarry, which tends to level out the difference in crushing performance.

Crusher Product Gradation Charts

When rock is crushed, the product includes material of the size of the crusher setting, some slightly larger and the rest of the material smaller than the crusher setting. Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the ...

Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
