crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen.
How to Optimize Reduction Ratio in Jaw Crusher?
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.
Tips to maximize crushing efficiency
Jaw crushers are routinely choke fed, as this maximizes production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, breaking up flaky or slabby particles. If you seek fewer fines, trickle feeding material into the jaw crusher could achieve this. But …

Evaluation of size reduction process for rock aggregates in cone crusher
The size reduction process of rocks in cone crushers is one of the most important issues, particularly for the secondary and tertiary stages of crushing operations. In this study, 17 different rock types were considered for the evaluation of their size reduction variations that occurred in a laboratory-scale cone crusher. Based on several mineralogical, physico …
Reduction Ratio Calculator
For example, if the feed material has a size of 100 millimeters (mm) and the product size after crushing is 20 mm, the reduction ratio would be 5:1 (100/20 = 5). This means that the crusher has reduced the size of the material by a factor of 5. ... This is often desirable in the aggregate and mining industries, where reducing the size of the ...
Effects of the recycled coarse aggregate mixing ratio on the
Specifically, at a mixing ratio of 15% recycled coarse aggregate, the reduction rate was −0.008% compared to regular concrete. This reduction rate decreased to −0.001% at a 20% recycled coarse aggregate mixing ratio and ranged between −0.007% to −0.009% at 25%.

How to Choose the Right Construction Equipment Supplier
All jaw crushers will fall into the range of a 6-8 to 1 reduction ratio. If you have an 18" piece of material and a 6 to 1 reduction ratio, you can expect a 3" product coming out of the jaw crusher. These ratios can be adjusted and tuned for your specific product requirements by adjusting the "closed side setting" in the action of the jaw.
