There are two kinds of. equipments used for crushing work s. one is by using crushers and other one is by using impacto rs. This diagram illustrates the stages of s ize reduction from 1000mm to 4 ...
Therefore, the crusher reduction ratio is 2. Calculating the Gape Size when the Crusher Reduction Ratio and the Set Size are Given. G = R r x S. Where: G = Gape Size R r = Crusher Reduction Ratio S = Set Size. Let's solve an example; Find the gape size when the crusher reduction ratio is 8 and the set size is 4. This implies that; R r ...
Balance Throughput & Reduction Ratio. Sometimes production capacity needs to be given priority over reduction ratios and vice versa. You can optimize for one over the other by adjusting certain cone crusher parameters. …
In practical applications, the reduction ratio calculation is used to: 1.Determine the suitability of an impact crusher for a particular application. Materials that require a high degree of size reduction, such as recycling concrete or crushing hard rock, benefit from crushers with a …
For a jaw crusher the reduction ratio (R) is defined with gape (G) as: (A.1) R = G L min [−] Therefore the close opening set ( L min ) for a jaw crusher can be written as: (A.1) L min = G R [ m ] Rose and English [4] determine the size for which 80% of the feed passed, by considering a large data set relating the maximum particle size to the ...
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It is …
