An amazingly simple recipe for nanometer-sized corundum
Oct 28, 2019· During work on the new method, it was demonstrated, both practically and theoretically, that it is possible to obtain nanometer-sized corundum while maintaining its stability and significant porosity. This effect was achieved by the appropriate selection of the operating parameters of the ball mills in which the milling occurred.
Micronization of a soft material: Air-jet and micro-ball ...
The yield achieved with the micro-ball mill was but was ∼80% for the air-jet mill, which reduced the size of Pluronic® F-68 from 70 μm to sizes ranging between 23-39 μm median diameters. Ball milling produced particles less than 10 μm after 15 min.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size.
See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.
