The modelling attempts to provide key insights into the performance mapping of the jaw crusher.

Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by opening or closing the gap between the jaw dies at the smallest point. This is referred to as the closed-side setting. If you need a smaller product size, move the jaw dies closer …
