Crushing Technology There are four basic ways to reduce size of a material: by impact, by compression, by shear or by attrition. Most crushers employ a combination of all these crushing methods. Impact Impact refers to the sharp, instantaneous collision of .
mostly of the mineral calcite and comprising about 15 percent of the earth's sedimentary crust. This mineral is a basic building block of the construction industry and the chief material from which aggregate, cement, lime, and building stone are made. For the purposes of this report, limestone will be used as a sample for crushed rock.
