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. the reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
Introduction to rock crusherselrus aggregate systemsjaw 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.
Crusher reduction ratio. i have mentioned the fact that, as the of voids in the crushing chamber decreases, the production of fines by attrition increases. this is like saying that, as the crusher reduction ratio in any given crusher is increased, the of fines in the product will increase, even though the discharge setting remains unchanged.
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 openside set (oss) is specified. this reflects the fact that considerable.
Total reduction ratio. source: metso. crushing is done in three, or four stages while grinding is done in one, or three stages. if you dont have many stages as shown on the app put 1 in the stages that you are not using. calculate the total reduction ratio of a milling circuit by multiplying the reduction ratios of every stage.
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.
