Introduction to Rock Crushers elrus

Sep 19, 20120183;32;Jaw crushers offer reduction ratios of up to about 61, while cone crushers can reduce material size up to a maximum of 81 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept.

Crusher Reduction Ratio Mineral Processing amp; Metallurgy

Crusher Reduction Ratio. Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 71 reduction should be handled in the latter machine. Generally, for such a case, the split would be about 31 to the standard machine, and 41 to the fine reduction crusher.

May 23, 20170183;32;A quot;best practicequot; strategy is to accept higher reduction ratio in secondary crushing so that it can be lowered in tertiary crushing. Another strategy to consider is to operate both the secondary crusher and the tertiary crusher in closed circuit with a wider closed side setting and an increased re circulation load from the sizing screens.

Construction Planning, Equipment, CHAPTER AGGREGATE

As stone passes through a crusher, the reduction in size may be expressed as reduction ratio. The reduction ratio is the ratio of crusher feed size to product size. The sizes are usually defined as the 80% passing size of the cumulative size distribution. For jaw crusher, the ratio can be estimated by the gape. CHAPTER 14. AGGREGATE PRODUCTION

Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery. Some crushers are mobile and can crush rocks as large as 1.5 meter (60 inches). Primarily used in pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced.
