Dec 01, 2020· The energy dissipation is split with 80% in rock-crusher collision (mechanisms 1, 2 and part of 4) and 20% in rock-rock collisions which is far from negligible (mechanism 3 and part of 4). This demonstrates that re-breakage from rock-rock collisions is an important minority component of the breakage process in the VSI.
