As little as 1% of applied energy may actually be used for size reduction. As the size of the piece is reduced, there are fewer lines of weakness available, and the breaking stress that must be exceeded increases. When no lines of weakness remain, new fissures must be created to reduce the particle size further, and this requires an additional

How Material Size Directly Affects Size Reduction Energy

Mar 25, 2015 While a jet mill is capable of reducing a particle populations average size by a factor of 1000, it takes a lot of energy to get there. As long as the application allows for it, other size reduction methods should be used to initially reduce the particle size as much as possible, and the jet mill should be used for the final size reduction ...

Unit Operation Size Reduction

Size Reduction Raw materials often occur in sizes that are too large to be used and, therefore, they must be reduced in size. This size-reduction operation can be divided into two major categories depending on whether the material is a solid or a liquid. All depend on the reaction to shearing forces. 1. The Mechanism of Size Reduction
