May 13, 2019 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 the closed-side setting, the greater the proportion of fines produced. The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees.

Perfecting the Performance of Secondary Crushers E amp MJ

A crusher is not able to directly produce a specific grain size, so the discharge always contains a wide range from fines up to a maximum size, plus oversize. The solution is a crushing circuit with an arrangement of a crusher, a subsequent screen and a conveyor to return the oversize to the crusher.

The T10 is useful as a single number which describes the Particle Size Distribution for the product from Crusher Discharge's operation relative to (size by size) feed size i.e. % passing 1/10th of parent size (s). Can T10, or a modified T10-type number, be used to describe qualitatively the internal PSD of a rock stream (in isolation from a crushing operation)?
