Introduction to Rock Crushers ELRUS Aggregate Systems

There are various types of rock crushers used in the aggregate industry including impact and roll crushers, but the most commonly used today are jaw and cone crushers. Jaw crushers normally take the mined material and reduce it to a manageable size -say 10 to 4 inches. Cone crushers take the material from a jaw crusher and further reduce the material size. Jaw crushers offer reduction ratios

Tips to maximize crushing efficiency Pit & Quarry : Pit

13/05/2019 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 finer

What does reduced ratio mean? AnswersToAll

16/03/2021 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. These production improvements come from a number of engineering changes, but a large part is due to better crushing chamber design.
