Ball Design Factors Size and Mass. Importance of size: Taggart (1927) stated "Size of balls should be proportional to the work to be done, i.e. the size of the particle that must be broken by impact, hence coarse feed and hard ores require larger balls than finer feeds and softer ores." The 9 to 10 m (30 to 33 ft) SAG mills now in wide use ...
