Typical Premix Media Mill Process:
Coating manufacturers have responded to requirements for fine grinds with the addition of multiple passes, alternative media types, or special multi-chamber high flow media mills. While the media mill remains the best choice for the "final grind", of some formulations, the process becomes inefficient when, typically the media mill is expected to take particles of 100 microns. A more efficient mixing process can be achieved by combining the "premix" and early milling stages into one step, PreMilling.
The KADY® PreMilling Process:
KADY® PreMilling quickly and efficiently delivers a premilled base to the media mill for the "final grind" - a single high speed KADY® Mill can provide a homogeneous "premix" and initial dispersion below 20 microns in less time than a typical premix: and the time required to finish the grind in the media mill will be greatly minimized.
Multiple media passes can be eliminated thereby reducing production and clean up time as well as duplication of expensive equipment. The KADY® mill employs a precision, close clearance rotor-stator turning at 9,000 FPM. This tremendous energy input into the mix batch (80% faster than other rotor-stator) leads to the superior dispersion results.
