A concept which has found some application for ball mills is the "angular spiral lining". The circular cross-section of a conventional mill is changed to a square cross-section with rounded corners by the addition of rubber-lined, flanged frames, which are offset to spiral in …


The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.


Figure 1 shows a schematic cross section of the Chadormalu iron ore complex SAG mill which consist of two rows of liners; (1) feed-end shell liners and (2) discharge-end shell liners. The present case study has been conducted on these well-worn liners. The liners were replaced after comminution of 800 thousand tons of iron ore.

The IM4000Plus Ar ion milling system provides two milling configurations in a single instrument. Previously two separate systems were needed to perform both cross section cutting (E-3500) and wide-area sample surface fine polishing (IM3000), but with 's IM4000Plus, both applications can be run within the same machine.


A lining for rotary mills comprising lifting and lining elements renewable by rotation and of a star-shaped cross section having substantially uniform points. The elements of the lining may have inner cooling passages constituted by tubes. The tubes may serve as rotational axes and supporting elements for the elements of the lining.


tomatic grinding, which could be important when the cross section at a specific depth is of interest. Automatic equipment is much more expensive than manual machines. Diamond abrasives are recommended for grinding most ceramics, but silicon carbide (SiC) paper and cubic boron nitride (CBN) platens can also be used.


In general, cross-section milling techniques are used for samples for which mechanical polishing is difficult, such as bulk samples or samples with multilayer structures. Fig. 1 Schematic diagram illustrating cross-section milling. As an example of cross-section milling, we present a …
