Crusher Reduction Ratio
Know MoreWe know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher than it is in the fine reduction crusher Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be ....
Cone Crusher
Know MoreThe 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 ....
