John Stuart Mill: Ethics. The ethical theory of John Stuart Mill () is most extensively articulated in his classical text Utilitarianism (1861). Its goal is to justify the utilitarian principle as the foundation of morals. This principle says actions are right in proportion as they tend to promote overall human happiness.

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond''s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closedcircuit dry grindability test performed in a standard rod mill.
See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um.
theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond''s equation is as follows: [6] where W is the work input (kWh/t); Wi is the work index (kWh/t) which expresses the resistance of the material to
83 Centrifugal force outward Fc mp 2 Dm 2 () is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg () The particle will remain against the wall if these two forces are in balance ie.
