Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.

In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer ...
The reduction ratio simply refers to how much area compression occurs when producing a hot rolled bar. Interestingly, the reduction ratio of 12:1 was once the norm and resulted in quality applications, but that is not always the case today. In fact, reduction ratios as low as 6:1 are now considered perfectly alright for many applications ...
AMIT 135: Lesson 8 Rod Mills – Mining Mill Operator . Rod Mill Operations Designed to accept feed from a secondary crusher. Feed particle size = 6 – 25 mm. Peripheral speed = 85- 146 m/min (280 – 480ft/m in) Reduction ratio = 2 – 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal
Bond proposes an optimum reduction ratio for rod mills [BON 61b, p. 545]. If the real ratio deviates, then W i must be multiplied by a correction coefficient (equation 26 in [BON 61b, p. 545]). For a ball mill, if the reduction ratio becomes less than 3 (target grinding of concentrates), the energy index W i must be multiplied by a given ...
No 1 rod mill/ball mill circuit was operating very efﬁ ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ﬁ ﬁ ner than 650 μm.
