- Reduction Ratio Of Cone Crusher
Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.

The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.
