3. if the rotation speed of the ball mill exceeds a certain limit (the rotation speed is very high), the steel ball rotates with the barrel without falling, and is in a centrifugal operation state. at this time, the steel ball has no impact effect, and the grinding effect is very small to stop the grinding.
Al., ). in stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. the bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach p80 10 to 40 .
Attritors or stirred ball mills are a simple and effective method of grinding and dispersing fine and homogenous material quickly. the attritor can operate wet or dry, introduce inert atmospheres, operate at controlled temperatures, and vary grinding speed. results are repeatable from one grind (batch) to another so the attritor is ideal for.
