Section snippets Mathematical model. In a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill.The production of fine material (final product) increased with increased feed rate, and the relationship is a straight line in log–log space.
Closed-Circuit or Open-Circuit Machines . Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction. A …
Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.
Similarly, the ball mill L/D ratio should not exceed 1.65. Each of the SAG/ball mill pairs shown in the various cases in the Table 1 example, will do the required grinding job and produce the specified tonnage of 471 t/h at a finished grind of 80% passing 75 µm. As in any trade-off study, there are also reasons to favour one configuration over ...

Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction. A typical closed system grinds the ore between …
Compared to the "reference point", a ball mill circuit closed with screens is expected to have 15–20% higher capacity at significantly lower circulating load due to …
Ball mill is not suitable for open-circuit process. Because ball mill itself does not have the ability to control grinding particle size, there are both qualified fine particles and unqualified coarse particles in the discharge. On the contrary, rod mill is suitable for open-circuit process.
Introduction. Tube mills having multi-chambers are traditionally used for cement grinding either in open or closed circuit operations. In the first chamber, larger balls (100–60 mm) are used for coarse grinding while the smaller balls (40–15 mm) are used for fine grinding.The chambers are separated by an intermediate diaphragm which …

ABC closed circuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill.
