Jan 22, 2016 The feed to a crusher should not contain an excessive amount of fine material; this could be stated a little more definitely by saying that it should not contain an excessive amount of material smaller than the crusher product size. Just what constitutes an “excessive amount” depends of course upon several factors, chief among which are the design of the crushing chamber, the setting, and ...

Apr 28, 2017 “Fines in the crusher feed” is defined as material entering the top of the crusher, which is already equal to or smaller than the crusher’s closed-side discharge setting. As a rule of thumb, the maximum number of fines in the crusher feed should not exceed 25 percent for secondary crushers or 10 percent for tertiary crushers.

May 13, 2019 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. ...

Feb 26, 2016 Gradation of the crusher feed also has its effect upon the product analysis. This is true even of screened feed, although deviations from the average are not likely to be so wide as they are for unscreened material, such as quarry-run or mine-run rock. We have commented on other variable factors, such as choke versus regulated feed, straight ...

This will lead to insufficient power utilization and abnormal increase in energy consumption during the crushing process. According to experience, for the secondary cone crusher, the proportion of fine material in the feed should not exceed 25%. For the tertiary cone crusher, the proportion of fine material in the feed should not exceed 10%.

Jul 26, 2017 As cone crusher liners wear, the operator threads the bowl inwards, bringing the bowl liner closer to the head which reduces the feed opening. The reduced feed opening may decrease crusher throughput at a cost; once that cost is greater than the price of the liner change you should consider changing the liners.
