Comparison of Milling Modes as a Pretreatment Method for .

Abstract—Here we proposed clean and acceptable pretreatment methods for the pretreatment of lignlicellulosic biomass. To prove the feasibility of it, we compared three modes of mills such as ball, attrition and planetary mills. Among the mill modes, attrition and planetary mills are more effective to reduce biomass size.

High Energy Ball Milling & How It Works | Union Process® Inc.

And, depending on your application, you may find that one type of high energy ball milling is more appropriate for your operation than another. In comparison with conventional ball mills, Attritors use fewer resources, including: Time, Energy, Media; Plant Space. In addition, Attritors offer the advantage of being able to take.
