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.

Increasing the speed of the rotor from nominal to maximum, will only increase the finer product discharge from the crusher by about 3%. But this also increase wear parts consumption and decreases the throughput of desired Size distribution of the product is affected by the following factors: • The work index of the material (Wi).

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.

Roller crusher. The particle size is generally controlled through the wedge between the two rollers or shim adjustment device. When the wedge is pulled up, the gap between the two rollers becomes larger, and the grain size of the discharge becomes larger. When the wedge is downward, the size of the discharge becomes smaller.
