The type of crusher influences the size and the shape of the aggregate result. In the primary crushing stage, pieces of rocks can be as large as 1.5 m, being reduced to a range between 10 and 20 cm by using heavy-duty machines. For this purpose, jaw and gyratory type ( Fig. 2.38) crushers are the most used devices. They are defined by a wide ...Web
