Dec 21, 2021 The grindability is up to the hardness, toughness and structure. The lower the grindability is, the more easily ball mill can process the minerals, the less the liner and steel balls wear, and the less the energy consumption is. Thus, you can change the grindability in order to improve ball mill efficiency.

Oct 25, 2017 The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
Nov 01, 2002 In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.
(Ball mill classification system optimization through functional performance modeling, Nov. 17, McIvor et al., 2017, Mining Engineering) described circuit classification system efficiency (CSE), equal to the percentage of coarse (plus circuit P80 target size) material in the ball mill. It can be measured and then increased through
Feb 13, 2017 Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15 x 21 to 8 x 12. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
