E = Wi*((100/d2)^0.5-(100/d1)^0.5)
This formula uses 4 Variables
Variables Used
Energy per Unit Mass of Feed - (Measured in Joule per Kilogram) - Energy per Unit Mass of Feed is the energy required to process one unit mass of feed for given operation.
Work Index - (Measured in Joule per Kilogram) - Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. Just as the meter is used to measure and compare distances.
Product Diameter - (Measured in Meter) - Product Diameter is the diameter of the sieve aperture that allows 80% of the mass of the ground material to pass.
Feed Diameter - (Measured in Meter) - Feed Diameter is the diameter of the sieve aperture that allows 80% of the mass of the feed to pass.
STEP 1: Convert Input(s) to Base Unit
Work Index: 11.6 Joule per Kilogram --> 11.6 Joule per Kilogram No Conversion Required
Product Diameter: 1.9 Meter --> 1.9 Meter No Conversion Required
Feed Diameter: 3.5 Meter --> 3.5 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
E = Wi*((100/d2)^0.5-(100/d1)^0.5) --> 11.6*((100/1.9)^0.5-(100/3.5)^0.5)
Evaluating ... ...
