|Size Reduction Actions
Types of size reduction
There are four ways to reduce a material: impact, attrition, shear, and compression.
Impact - a sudden force occurring when one object collides with another
Attrition - frictional force applied to the material due to the opposing motion of two
Shear - a force applied when the material is compressed between the edges of two hard
surfaces moving tangentially
Compression - force applied by the faces of hard surfaces moving towards each other
Each of the following types of mill use a combination these types of size reduction.
