In Grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery andor mill liner wear and

The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. 3 The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding wetdry. None of the characteristics of the material being ground have any influence on K 1.
ball mill and ball charging systems australia Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

Guidance Manual for Nonmetallic Mineral . Aug 31, 1983 Subpart OOO.3 To determine primary crushing capacity, it is necessary to look at all initial must comply e.g., Subpart F and Subpart I. used for tertiary crushing and rod mills, ball mills, and hammermills are used in the milling stage. jaw crusher can be categorized by the size of its feed opening and
1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material grain size, hardness, density, temperature and humidity, the degree of
