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).

Impact crushers, in turn, utilize the impact principle. Our Jaw crushers are mainly used as primary crushers. Their main purpose is to reduce the material to a small enough size that it can be transported by conveyors to the next crushing stages. Our jaw crushers reduce rock and other materials between a fixed and a moving jaw.

Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.

Impact Crusher The impact crusher uses the energy contained in falling stone, plus the power imparted by the massive impellers. Rock fed into the impact crusher falls directly on to the impellers and rotates away from each other, turning up and outward, at speeds from 250 to 1000 rpm depending on the desired size of finished product.
