The company coal internal work through three roller mill ...
WhatsApp: +86 18203695377The 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).
WhatsApp: +86 18203695377Mediumspeed mill. Mediumspeed mills are smaller than lowspeed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.
