I. INTRODUCTION AND PRINCIPLES In this presentation we will discuss the principle of the Attritor and its applications. The Attritor is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." There are quite a few types of Attritors; we can categorize them as dry grind
The mixture of powders were grinding in ball mill for 48 h, and after drying, and sieving, mechanical synthesis was conducted in shaker-mill for 5, 10, 15 and 20 h. After activation of 5 h almost all the sharp peaks of PbO, ZrO 2 and TiO 2 had been vanished and replaced by a few broadening peaks implied that there was a rapid …
