Grinding characteristics of crystalline graphite in a low ...

2002-6-27  Crystalline flaky graphite was ground in a dry attrition system equipped with a vacuum apparatus. It was found that a low-pressure and high-temperature environment in the grinding of graphite promotes the size reduction down to submicron sizes while maintaining flaky shape.

Investigation on the grinding properties of high

2020-3-2  In order to analyze the effect of graphite addition on the properties of vitrified bond CBN grinding wheel samples, different amounts of graphite (0, 2, 4, 6 wt%) were added to the vitrified bonder. When the graphite addition is 2 wt%, the refractoriness, fluidity, and bending strength of the grinding wheel samples are better than those of conventional vitrified bond grinding wheel samples.
