2013-6-26 · Tsinker defines crushing as the complete failure of granularization of the solid ice sheet into particles of grains or crystal dimension; no cracking, flaking, or any other failure mode occurs during pure crushing. Specific models that correspond to ice in crushing failure are given in [3, 16]. Even though these two articles model the same physical phenomena, they are different in their modelling approaches.

Crushers

If the intermediate crushing is done with the purpose of producing railway ballast, the quality of the product is important. In other cases, there normally are no quality requirements, except that the product be suitable for fine crushing. Cone crushers are often used for intermediate crushing, due to their high capacity and low operating costs.
