How it works

The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding discs. Media recirculates between the rotating discs distributing grinding action throughout the IsaMill™. Grinding is by attrition and abrasion of the particles in contact with the high speed, small, circulating media.

Ball Mills - an overview | ScienceDirect Topics

In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills. In high-energy ball milling, formation of ceramic nano-reinforcement by in situ reaction is possible.

Energy efficiency

Traditionally, the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling. However, the most important factor for fine grinding is media size and therefore the breakage rate. Small media has a larger surface area, which translates to better transfer of energy.
