The correction factor is given as (3.41) F 7 = 2.44 D 0.2 for D < 3.81 m F 7 = 0. 914 for D ≥ 3. 81 m where the mill diameter, D, is in metres. It has been shown by Bond that for mills larger than 3.81 m, the reduction in grinding energy resulting from mill diameter ceases and the correction factor is constant at the 3.81 m value of 0.914.

To determine power factor (PF), divide working power (kW) by apparent power (kVA) . In a linear or sinusoidal system, the result is also referred to as the cosine θ.. For example, if you had a boring mill that was operating at 100 kW and the apparent power consumed was 125 kVA, you would divide 100 by 125 and come up with a power factor of 0 .80 .

Erosion in a paper mill is also a concern. Erosive slurries including pulp stock and lime mud can severely erode the internals of control valves, thus minimizing the service life of the product. In some cases, the erosion is severe enough to cause pressure boundary parts to become unstable. This is a safety risk to the mill.

To use the right correction bolus, you first determine your correction factor. The 1500 Rule for Regular was originally developed by Paul Davidson, M.D. in Atlanta, Georgia. Because the blood sugar tends to drop faster and farther on Humalog and Novolog insulins, we modified the 1500 Rule to an 1800 Rule for these insulins.
