Crushing technology -

If the permissible marginal conditions, such as feed size, feed grain composition and reduction ratio are observed, a cone crusher produces grain sizes that meet the standards provided that the stone properties permit this. Costs The operating costs of a cone crusher are slightly higher than a jaw crusher. However, in hard, abrasive stone, they are considerably lower than an impact crusher

Crushers and Their Types – IspatGuru

Crushers and Their Types. A crusher is a multi dimensional machine which is designed to reduce large size materials into smaller size materials. 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 the case of ore), so that pieces of

Tips to maximize crushing efficiency - Pit &

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
