5.8: John Stuart Mill: Utilitarianism (Part 2

For—besides that the existence of such a moral instinct is itself one of the matters in dispute—those believers in it who have any pretensions to philosophy, have been obliged to abandon the idea that it discerns what is right or wrong in the particular case in hand, as our other senses discern the sight or sound actually present.

A comparison of SAG mill power models

the mill shell. The measured power is 3,190 kW at mill shell, so the model predicts high by 298 kW, or 9%. However, by substituting the recommended 5% allowance for a cone end instead of Austin's cone allowance results in a 148 kW of power generated in the cone, for a total of 3,113 kW power draw at the mill shell.

Mill drives: the desire for increased power and the

secondary mill power that permits the range of vari- ability samples to be processed according to whether a "SAG Mill limiting" condition, i.e., harder ore, or a "Ball Mill limiting" condition, i.e., softer ore exists. For example, a ratio of 1:1.5 or up to 1:2 would indicate a trend away from processing harder ore types and

J.S. Mill's On Liberty: Seek Disagreement

John Stuart Mill lived from 1806-1873, during the height of Victorian Era England. This is important because, though he is perhaps best known for his role in developing utilitarianism, Mill was particularly interested in the social and political problems of the Victorian Era, and in much of his work he sought a practical influence.

Wills' Mineral Processing Technology, 8th Edition

It is performed in cylindrical steel vessels that contain a charge of loose crushing bodies—the grinding medium—which is free to move inside the mill, thus comminuting the ore particles. According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills .

SAG Mill Liner Design

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

Choosing a SAG Mill to Achieve Design Performance

viewed through the open end of the SAG mill, it was evident that maximum throughput occurred when the cascading material (for clockwise mill rotation), was hitting the shell at 30o to the right of the vertical diameter (or 5 o'clock). This impact point was normal to the mill shell tangent at that point.
