In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.The MCD 2000 Corundum Disk Mill is an inline mill for wet milling and grinding of viscous liquid or paste-like products.

I'm very much into wood working which involves some hand tool sharpening. In the sharpening world, we're very familiar with abrasives. Some people use sandpaper taped to a piece of plate glass or a flat granite tile working from course (say 400) to fine (say P2000 wet). Other people use a wet stone which is basically a block of adhesived together Aluminum Oxide (the mainCorundum, derived from India, is a mineralogical name. There are three main variants of corundum Al2O3, which are α-Al2O3, β-Al2O3, and γ-Al2O3. Corundum is second only to diamond in hardness. Corundum is mainly used for high-grade abrasive materials, bearing materials for watches and precision machinery. Ruby-based artificial crystal as a ...

The present invention relates to a process for the preparation of silane modified nano-corundum, in which the nano-corundum aggregates are deaggregated in the presence of an organic solvent and simultaneously or subsequently treated with silane. n α-alumina, deagglomeration, microcrystals, nanoparticles, silanes.

A rapid vibro-milling technique (McCrone micronising mill) was employed in order to combine mixing capability with a significant time saving (only 12 h instead of 24 h, as required in conventional ball-milling (Ananta, 2004(a)). The milling operation was carried out in isopropanal. High-purity corundum cylindrical media were used as the milling ...At the Max-Planck-Institut für Kohlenforschung in Mülheim an der Ruhr, chemists have identified a new method to synthesize a nanoparticle form of corundum by employing simple mechanochemistry in a ball mill.

NutriMill Harvest. With its laminated bamboo cabinet, the new NutriMill Harvest grain mill offers unique styling.
