Back to Basics Hammer Milling and Jet Milling
网页There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill. As an alternative, water can be added to the material and it can be ground wet; this solution is suitable for ham- mer mill operation but not for jet mills.
