RR (Reduction Ratio) is a ratio of a measure at the open side behaviour of the crusher divided by a closed side measure. • PRR (Process reduction ratio) = F80/P80, where F80 is the size for which 80% of the feed is smaller and P80 is the size at which 80% of the product is smaller. • LRR (Linear reduction ratio) = OSS/CSS.

Continuing process and crusher control help to attain high availability with optimum ...
Usually, these crushers deliver a 4:1, 5:1, or 6:1 reduction ratio. As you reduce the closed side setting to produce smaller material, you also reduce the capacity of the machine. ... High Crushing Ratio. Cone crushers also have a high crushing ratio, and they're able to quickly process raw material to a more uniformly fine size than first ...
The steep head angle in ® GP220™ cone crusher ensures trouble-free operation in varying feed conditions with a high reduction ratio. Continuing process and crusher control help to attain high availability with optimum production levels of …
® HP200™ cone crusher is a versatile crusher often utilized in aggregates production and quarrying operations. ... ® HP200™ cone crusher has a higher output capacity, higher density in the crushing chamber and better reduction ratio, producing higher on-spec yield end products with the same energy consumption. ...
Introducing the Cone Crusher. Cone crushers take care of secondary and tertiary crushing applications. Fine and medium-sized aggregates (used in asphalt and concrete, for example) are created by an eccentrically rotating shaft that grinds the rocks between a robust metal cone and a fixed wall. The Blackhawk 100 Cone Crusher is an example of …
In most cases, cone crushers provide reduction ratios of 4:1 and up to 6:1 (meaning the ratio of the feed size to the crusher versus the size of the crusher discharge). "The reduction ratio design …

Cone crushers are used in the aggregates and mining industries to crush rock material. The pressure on cone crusher liners is the key factor that influences the hydraulic pressure, power draw and liner wear. In order to …
Relatively low reduction ratio; Hydraulic Cone Crusher. The hydraulic cone crusher is a modern and advanced version of the spring cone crusher. It uses hydraulic cylinders to adjust the size of the …
In other words, an impact crusher can reduce the material significantly more than a jaw and cone crusher. The ratio of input size vs the output size describes the so-called reduction ratio. ...
