Crusher Size Reduction Ratio. Most largescale crusher size reduction ratio using a threestage crushing process closed circuit. In coarse, medium and fine threestage crushing process, the main choice is the key equipment cone crusher. Therefore, select the appropriate cone crusher is the key "multi break less grinding" can be realized.
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
However, for best practice, both should be adjusted proportionately to maintain a correct reduction ratio and highest product quality. When it comes to production capacities of impact crushers compared to jaw and cone crushers for the crushing and screening of RAP, Ryan Freeman, the general manager at Rason Materials, shared his experience.
May 23, 2017 · A "best practice" 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 recirculation load from the sizing screens.
Oct 04, 2019 · JAW CRUSHER. 8:1 maximum reduction ratio for compression crushing, this is normally used as a primary crusher. Jaws perform well in many materials. Yields low wear cost per ton in hard abrasive deposits, minimal fines but produces little finished (under 1") product which places more load on the crushers downstream in the circuit.
We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volumereductionratio in the standard gyratory is considerably higher than it is in the fine reduction crusher. Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be

Sep 19, 2012 · Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 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.
crushers provide high reduction ratios. Because of their efficient crushing action, the crushers have a large power utilisation per cone diameter. The high cavity density improves interparticular crushing action for end products, with a more consistent gradation and superior product shape (cubicity). 4 5
The difference between a conventional impactor and a VSI of the Barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a Barmac VSI, the material undergoes an intense rockonrock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.
The anvil solution improves reduction ratio and enables finer end products, but the downside is slightly higher wear costs because the anvils must be replaced from time to time. Barmac® B Series™ VSI crushers accept fines in the feed and allow user to finetune crusher''s performance by changing the rotor speed or cascade ratio.
