Introduction: Jaw crushers are essential machines used in the mining and aggregate industries to break down large rocks into smaller, more manageable sizes. The primary function of a jaw crusher is to reduce the size of the material to a specific size range, commonly referred to as the 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. Both of these …
