contact us· Crusher 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.
contact usImpact crushers (also known as impactors or horizontal shaft impactors) can be used in primary, secondary, or tertiary applications. They use inertia of the blowbars fitted to the rotor to fracture the material, resulting in a high reduction ratio.

contact usJaw crushers are generally considered a primary or first-stage crusher. The maximum feed size can be as large as 80–85% of the crusher''s gape or depth, while reduction ratios range from 2–3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher has begun the reduction process earlier in the circuit.
contact us5.1.2 Impact crushers Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact ...
contact usA general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4" closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may …

contact usThe first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary (second), tertiary (third) or quaternary (fourth) crushers. Reduction Ratio The ratio of the top size of input material to the top size of crusher discharge material. Run of Mine (ROM)
contact us· Impact crushers (rotary or hammer mills) have the capacity for high reduction ratios (up to 40:1), but are rarely applied to hard rock mines. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers.
contact us· It calculated by multiplying reduction ratios of all the stages (see formula below). R/R=R/R1*R/R2*….R/Rn. n number of milling stages. R/Rp reduction ratio of the p stage . Source: formula.minerallurgy. For example in a crushing circuit that consists of a jaw crusher (3/1), and a cone crusher ( 5/1), has a total reduction ratio of 15/1.

contact usImpact crushers provide better grain-size distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material.
contact usPrimary Impact Crushers are preferred for their high capacity and reduction ratios in crushing soft and medium hard rocks like limestone, gypsum. Due to their operating principle, reduction ratio is higher than in jaw crushers.
contact usVSI and GS series crushers are characterized by a unique closed-rotor design providing a higher reduction ratio with lower wear cost.

contact us· Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
