the ball-milling of cellulose fibers and recrystallization effects cellulose fibers. more recently, when samples of widely varying crystallinity were required for fine structure analysis, the same ball-milled samples were used for
following an extensive feasibility study, a hpgr-ball milling circuit was justified based on the reduced power requirements and reduced operating expenses relative to sag milling. the hpgr-ball mill circuit was estimated to require 75% of the energy of a standard semi-autogenous grinding sag mill circuit.
