Sep 19 32 Jaw crushers offer reduction ratios of up to about 6 1 while cone crushers can reduce material size up to a maximum of 8 1 ratio The finer the crushing the smaller the reduction ratio As a basic rule jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept Cone crushers tend Oct 20 32 That all depends on the geology the deposit density the metal you are trying to extract and the specific extraction process There are other factors but these are the main criteria used to determine the ROI for a mines financial viability Too

A crusher is a machine designed to reduce large rocks into smaller rocks gravel or rock dust Crushers may be used to reduce the size or change the form of waste materials so they can be more easily disposed of or recycled or to reduce the size of a solid mix of raw materials as in rock ore so that pieces of different composition can be differentiated8 1 maximum reduction ratio for compression crushing this is normally used as a primary crusher Jaws perform well in many materials Yields low wear cost per ton in hard abrasive deposits minimal fines but produces little finished under 1” product which places more load
