DE-11: Lesson 43. SIZE REDUCTION

Shear forces are best applied to relatively soft materials, again including fibrous foods. All three types of force are generated in most types of mill, but generally one predominates. For example, in most roller mills compression is the dominant force, impact forces feature strongly in hammer mills and shear forces are dominant in disc attrition

Home | Torrey Mills - Three Roll Mill

The three roll mill is a dispersing tool. As fine particles tend to agglomerate in traditional agitators, a three roll mill applies tremendous shear force to break apart those agglomerates. With the capability to reduce particles down to 1 micron, the three roll mill is versatile enough for a variety of high shear applications. FREE Brochure.
