DetailsClosed Circuit is defi ned as a combination of a crusher and one or more screens were all or parts of the material will pass the crusher. Over sized material will then be re-circulated to somewhere before the crusher and thereby fed to the crusher again to be re-crushed. Parts of the rock material will thereby pass the crusher more then once.
DetailsThe degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced. Primary crushing is the first stage of material reduction and can sometimes be …
