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
May 13 2019 · Additionally jaw crusher feed should be prescreened using a grizzly screen prior to crushing to remove material finer than the closedside setting Setting jaw crushers Ideally the reduction ratio of a jaw crusher should be 6to1 There are different ways to calculate reduction ratio but the best way is something called the P80 factor
CHAPTER 14 AGGREGATE PRODUCTION ENCE 420 ©Assakkaf Slide No 6 TYPES OF CRUSHERS 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
Cone crushers are critical pieces for aggregate production mineral processing operations and recycling applications They’re typically a secondary or tertiary rock crusher and produce a fine or mediumsized aggregate material Since cone crushers have a large feed opening and small discharge sizes this type of aggregate equipment has a high crushing ratio making them quite efficient on
Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt PA mixture To determine the technical requirements of crushing value of coarse aggregate used in PA mixture steploading compression tests were conducted on the mixtures of PA13 and a control asphalt mixture AC13 respectively
Calculation of Aggregate Crushing Value Aggregate crushing value can be found by the following formula “Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 236 mm IS Sieve divided by weight of aggregate sample taken for test” Aggregate crushing value W3 W or W3 W2 – W1
