Re: Grindiability & Mill Shaft Power. There is no direct relationship between Bond Work Index and the shaft power, just as there is no direct relationship with grindability. You can calculate the grindability of different materials ground on your composite milling system simply from the total kWh/t consumed to grind to a particular fineness.
