Apr 08, 2008 First buy a Infra-Red thermometer with adjustable emissivity. Stop your mill. Measure the surface temperature with a contact thermometer. Then measure the temperature with the IR themometer and adjust the emissivity setting until the reading is the same as the contact temperature. When you obtain a correct fit, you get a measure of the emissivity.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
