Ore Crushing

In 1950, the American Fred Chester Bond put forward the "crack theory," which believed that "the power consumption of the crushing process is proportional to the length of the cracks formed during the crushing process." The theory became the widely used "third theory" of crushing and is suitable for medium and fine crushing.

Crusher Close Side Settings

The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
