Powder Handling: Size Up Size Reduction | Chemical Processing
Aug 14, 2017 · There are three basic types of size reduction: 1. Crushing, in which material usually is forced between two machine elements; 2. Impaction, in which equipment components or an outside force hit the material; and. 3. Attrition or grinding, in which rubbing or friction reduces material size. Fineness is an indior of the quality of the mill or ...
Micronization of a soft material: airjet and microball milling
The feed rate of the material into the air jet mill was a significant factor and slower feed rates lead to smaller sizes by allowing more time for particle collisions and subsequent particle breakage to occur. Microball milling under cold condition was more successful at achieving a lower range particle size reduction of soft materials.
