The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure ). A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle ( Figure (a) ) and it is the most widely used in primary crushing stages ( Behera et al., 2014 ).
Cone Crushers. A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point.
