Reduction Ratio Of Jaw Crusher

Mathematically, the reduction ratio is calculated by dividing the size of the feed material by the size of the product. For example, if the feed material has a size of 100 millimeters (mm) and the product size after crushing …

Cone crushers are similar to jaw crushers in that they are relatively low wear. Impact Crushers: Impact crushers can yield a considerably higher reduction than jaws or cones, from 12-15 to 1. This means one can take a 12" or 15" piece …

For a given ratio-of-reduction, the type of crusher with a flared crushing chamber will usually deliver a cleaner product than any of the older types; conversely, more reduction can be performed in the machine without creating excessive fines.

Unlike jaw and gyratory crushers, where reduction is progressive by repeated nipping action as the material passes down to the discharge, the crushing process in rolls is one of single pressure. ... the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 are rare, a flowsheet may require coarse ...

What Is A Reduction Ratio Of Crusher? The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments.

be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-

Cone crusher size reduction control (Itävuo et al., 2012, ... On the other hand, economic KPIs J 1-J 2 favor higher reduction ratios because 5/16 mm is the most valued product. The difference between J 1 and J 2 is caused by the influence of total throughput J 4; ...

Required reduction ratio; A jaw crusher size is obtained by looking at its feed opening (gape) and length. As an example, a monster 7959 of 79″ x 59″ (2m x 1.5m) will have its fixed jaws 79″ apart where the feed enters on a 59″ wide set of liner plates. The factors list below will enhance crusher capacity and performance: 1.

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. ... Reduction ratio example: jaw, cone, impactor Maximum reduction ratio Feed material Output size; Jaw crusher: 6:1: 24" 4" Impact crusher: 24:1: 24" 1 ...

Ideally, the reduction ratio of a jaw crusher should be 6:1. 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 per cent versus the discharge size that passes 80 per cent. The finer the CSS, the greater the ...

Example, C80 jaw crusher, 2″ CSS: Q = 0.8*(0.05+0.025)*0.025*cot(10°)*1.75*350*60 = 111 m³/h ... pattern to produce larger rock that can be handled by a larger loader-hauler combination and still fit in the primary crusher. Generally, a large reduction ratio will be required of the primary crusher. Typical Capacities of …

Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by opening or closing the gap between the jaw dies at the smallest point.

This angle determines the ratio of reduction of the jaw crusher. The smaller this angle, the lower the reduction ratio. A jaw angle of 15-20° results in a reduction ratio of 4 to 6. Various jaw crushers with different design features have been developed; of them generally two types remained master of the field, namely the double-tog­ gle jaw ...
