A preliminary simulation model for fine grinding in high

Jun 25, 2004 This is conveniently done by dividing the specific energy range into N small linear sections of Δ E. Letting EN be the initial specific impact energy at the instant of original impact, then Δ E = EN / N. Indexing the energy classes by k, starting with k =1 for the lowest gives the specific energy of the k th energy class as Ek = k Δ E.
