The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore.The usual reduction ratio is about8. According to Bond, the reduction ratio is a function of length and diameter of the mill. get price. rod mills with high reduction ratio Grinding Mill China.
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.
Attrition Mills Size reduction in attrition mills occurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. 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 ...
