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.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.

To calculate primer efficiency values, use the following equation. The formula to do this in Excel can be found below. = (10^ (-1/The Slope Value)-1)*100. This will give you a primer efficiency score as a percentage. Hopefully, this is between 90 – 110%. By using the above dataset, the efficiency comes to 98%.

How to Calculate Efficiency. The efficiency equation is a comparison of the work output from an operation to the work input to that same operation. The amount of "work" could refer to time, effort, capacity, or more tangible items. A high level of efficiency implies a minimal amount of wasted time, effort, capacity, materials, and so forth.

The ECT formula you asked for can be shown as: ECT greater than 32 = 0.212 (sum of the CDRC values) minus 6 OR 1.27 (RC liners/6) + (RC medium x take-up Factor)/6 -6. The predicted range of potential ECT values off the corrugator operation at 100% efficiency would be 31-48# for a 42/26C/42 and 46-60# for a 42/40C/42 combination.
