Grinding Classifying Improvement

Improvement of grinding and classifying performance …

High efforts have been made to increase grinding efbullet5ciency in toner manufacture. Higher efbullet5ciency is needed because energy increases in grinding and classifying processes as the particle size becomes smaller and particle distribution narrower. In the past, jet mills were widely used for toner grinding.
