WebOct 9, 2024 · The Third Law of Comminution, also known as the Bond’s Law, is summarized in Equation (1) [5]. W = 10wi 1 p P80 1 p F80 (1) wherein: W is the specific power consumption [kWh/t]; w iis the Bond work index [kWh/t]; P80is 80% passing size in the grinding product particle size distribution (PSD); F80is 80% passing size in the feed PSD. WebAs calculated using the Bond equation, W can be con verted to kilowatt-hour per metric ton by mUltiplying the value obtained by 1. 102. If the measured power for the operating work index is given as kilowatt -hour per metric ton (kWh/t), then the calculated work index is power per metric ton.
