The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments. However, the best particle shape is found in material about the same size as the CSS, which is the smallest discharge opening dimension on the jaw

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.
