The IsaMill is unlike any other grinding mill1: • It is very high intensity – 300kW/m3, compared with typically 20kW/m3 for ball mills. This means it is easily installed in a small area. • It produces a very sharp size distribution in open circuit. This is due to 8 grinding chambers in series, closed with an internal centrifugal classifier.
ISAMILL® is in fact a large version of the Netszch horizontal stirred mill which was being used for various ultrafine grinding applications in various chemical processing industries.
