reduction ratio of secondary crushers from ghana

The operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact [5]. The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25 and 30 . The Gyradisc crushers have head diameters from ...
