Typically, the high-speed stirred ball mill produced broader particle size distribution yielding distribution modulus (DM) of 0.213 as opposed to 0.384 for the conventional mill. Rheological data collected on a typical distribution constructed based on the Farris analysis revealed that suspensions were most viscous for particles ground in the pin device followed by the disc device and the ...

Mill Speed
However, very high mill speeds could lead to high wear of the balls inducing high contamination, excessive heating and lower powder yields. The size of the milling media (typically 20:1 for ball:powder diameter) also influences size, morphology and microstructure of the powder.
