[PDF]Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm).

Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

The width of the jaw determines capacity. Jaw crusher output gradation is controlled by the closed side setting. This is the adjustable opening at the bottom of the jaw. With a 24" top size limit and an 8:1 reduction ration, the closed side setting should be no smaller than 3". A well designed jaw should be 80 to 85 percent efficient.

Reduction ratio The reduction ratio is the ratio between the size of feed and the size of the outgoing product. It is normally measured at the 80% passing point.
