FINE GRINDING OF CERAMIC PARTICLES IN ATTRITION MILL |
摘要 |
<p>A process of grinding ceramic materials such as zirconia comprises grinding in an agitated media-type mill in the presence of a dispersant, the process being characterised in that the grinding media has a particle size of from 0.8 3.0 mm, and in that the quantity of media present is such that the average stand-off distance between adjacent media particles is from 30-90 um. The preferred apparatus is an attrition mill with an additional holding tank which allows recycling. The ceramic powders thus produced are fine with an unusually narrow particle size distribution.</p> |
