Calculating Screen Efficiency Example. 3/2/2016 8 Particle Size The closer the particle size to the aperture, the harder to pass it. “Half Size” and smaller go fairly easily. −¼” particle, ½” aperture, e.g. “Near Size” takes a lot more time. 3/8” Particle 3/8” / 1/2” = 0.75 7/16” / 1/2” = 0.875 7/16” Particle
→of the factors affecting screen efficiency. The old formulas were designed to keep calculations short and manageable for manual calculation. The common use of computers in today’s world makes it possible to do more complex screen capacity calculations in much shorter time. This allows for the inclusion of more and more subtle factors, which greatly increase the accuracy of the conclusions
