Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill
Let us first consider the fourth trait which adverts to relation between quality of pleasure and quantity of pleasure. Mill's distinction of quality and quantity in pleasure has to be based on one crucial supposition, which Mill does not, however, explicitly mention. He must not admit any possible measurability (reducibility)

In this paper, I firstly intend to provide an explanation of Mill's distinction of "higher" and "lower pleasures regarding these claims. Secondly, I shall introduce the method of calculating overall utility (Mill refers as "the only thing desirable as ends") considering both quantities and qualities involving these claims (Mill, p.187).
stirred mill with high distinction. IsaMill - Wikipedia The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Free Quote

al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.

High Energy Ball Milling. In discussions on high energy ball milling, the more generic term "ball mills" is often used in place of the terms "stirred ball mills" or "Attritors," but the differences between the types of mills are quite distinct.
The HIGmill comprises a mill body, shaft with grinding discs, shell mounted counter rings, gearbox, and drive. The grinding chamber is filled up to 70% with grinding beads. Rotating discs stir the charge and grinding takes place between beads by attrition. The number of discs (grinding stages) depends on the application and can be as high as 30.

John Stuart Mill also makes a clear distinction between high and low pleasure, an aspect that his tutor Jeremy Bentham did not deal with. That is why; we can claim that Mill's unique contribution to Utilitarianism is his view on the separation of pleasures considering their quality.
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Operating principle – fluidized-media stirred mills In contrast to the gravity-induced stirred mills, the fluidized mill type uses high rotational speeds of either impellers or discs to cause the suspension and complete mixing of the grinding media and slurry particles. The fluidization compels the slurry particles and grinding media to
The high intensity in the IsaMill™ means small media can break coarse particles. The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood.
