The paper presents a study on the effect of high energy milling to the crystallite size and lattice strain of α-alumina in zirconia and corundum mills. A Fritsch Pervesette 7 which has a maximum milling speed of 1100 rpm was used for this comparison. Milled samples were analyzed using the X-Ray Diffraction (XRD) technique to calculate for the crystallite size using the Scherrer …
The Craigmont Mine (originally the Craig Mine) was once a relatively large mine in the world of industrial minerals. It There was a large mill building on site and corundum ore was extracted from several pits. The operations of the Craigmont Mine were all within the first 20 years of the 20th century. It has not operated since.
ent milling media were used in order to assess their influence. If ma-terials are produced, such as supp orted catalysts or nano-corundum, one should use inert milling media, so that the properties of the pro-duced solid are not substantially affected by the contamination due to abrasion. For the synthesis of nano-corundum, milling jar and me-
Different machining processes such as ultrasonic machining and grinding by a diamond wheel produce varying degrees of surface damage. The amount of surface damage appeared to be related to the type of machining process. However, the degree of surface damage could not be related to the surface roughness for different machining processes. The surface damage …

In these milling operations, the dried crude drug may be cut by sharp blades (cutter mill), impacted by hammers or crushed/compressed by the application of pressure (roller mill, pestle and mortar). As a limited amount of energy is imparted, the milled particles remain relatively coarse.
Corundum. Corundum is a crystalline form of aluminum oxide (Al2O3) with traces of iron, titanium and chromium. It is a rock-forming mineral. It is one of the naturally transparent materials, but can have different colors when impurities are present.
When micrometer-sized preformed corundum is milled, it is also severely contaminated with milling media and jar material. Our approach reported in ( 1 ) presents a simple procedure, enabling easy access to high-surface-area α-Al 2 O 3, from which impurities, if any, can easily be removed, or can be avoided altogether, if milling proceeds in ...
