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 Attritors, wet grind Attritors, regular speed Attritors, and

Wet ball mill: The working principle of the wet ball mill is similar to that of the dry ball mill, but there are differences. The wet ball mill needs to add an appropriate amount of water or absolute ethanol during the grinding process, which means that there are certain requirements for the concentration of grinding. The amount of water is determined by the nature of the material. …

Abstract: Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively, while guaranteeing producing safely and stably. The grinding process is essentially a multi-input multi-output system (MIMO) with large inertia, strong coupling and uncertainty characteristics. Furthermore, being unable to
