Jaw Crusher Diagram: Simplified Guide

In a crusher's design, attention to the reduction ratio is critical. This ratio reflects the degree to which the material is reduced in size from the feed to the product. A high reduction ratio indicates a powerful crushing capacity, such as reducing 150-centimeter-wide iron ore to a 30-centimeter-wide material.
