A well-graded feed for a Jaw Crusher includes material larger than the closed-side setting but no larger than 80% of the feed opening. As stated in the two previous best practices, remove oversize, fines and material equal to the product size ahead of time for optimum operation. 6. Avoid feeding lightweight or sticky material

One commonly used empirical formula for jaw crusher capacity calculation is: Capacity = (Feed rate) x (Feed size factor) x (Material factor) x (CSS factor) x (Speed factor) Where: Feed rate is the rate at which material is fed into the …

Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.

If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the crushing chamber busy.

velocity, the feed rate and the feed size distribution. The model is based on the standard matrix formulation that includes classification and breakage matrices. ... accurate wear rate. The performance of jaw crusher is mainly determined by the kinetic characteristic of the liner during the crushing process. The practical kinetic

Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher. The equation proposed by Hersam includes a number of constants that are only qualitatively …

Feeding Jaw Crushers. It is desirable to feed jaw crushers continuously. However, feed is often provided intermittently using front end loaders, shovels or trucks. When the feed rate exceeds …

To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known. The 1½-in. screen under the jaw crusher is the top deck—no deck correction factor will be necessary. …

the crusher and scalp out fi nes. Primary gyratory crushers – ideally suited to all high-capacity primary hard rock crushing applications. Jaw crushers – we have more installed jaw crushers than anyone in the world. The lead-ing choice due to their high reduction ratio and heavy duty design. Cone crushers – capacities available to suit all

Designs of different types of jaw crushers such as Blake, Dodge with single and double toggles used for initial comminution of minerals, as received from mines, are described in detail. The method of calculating operating variables such as the critical speed, toggle frequency and throw and power consumptions are explained and illustrated with practical examples with …
