the three types of crushers most commonly used for crushing cdw materials are the jaw crusher, the impact crusher and the gyratory crusher (figure 4.4). a jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle ( figure 4.4(a) ) and it is the most widely used in primary crushing stages ( behera et al., 2014 ).
