WebJul 7, 2024 · The four basic techniques used in size reduction of dry powders are impact, shear, attrition and compression forces. In some cases, a combination of these may be found in a single mill type. Impact and attrition size-reduction methods include air classifying mills, pin mills, hammer mills and jet mills.

As load is applied to a material, the material elongates and the cross-sectional area is reduced. This reduction in cross-sectional area is called lateral strain, and it is related to the axial strain by Poisson's ratio, ν. For a circular specimen this reduction in area is realized as a reduction in diameter, and the Poisson's … See more The relationship between stress and strain in a material is determined by subjecting a material specimen to a tension or compression test. In … See more Below the proportionality limit of the stress-strain curve, the relationship between stress and strain is linear. The slope of this linear portion of the stress-strain curve is the elastic modulus, E, also referred to as the … See more Up to the elastic limit, the strain in the material is also elastic and will be recovered when the load is removed so that the material returns to its original length. However, if the material is loaded beyond the elastic … See more After a material yields, it begins to experience a high rate of plastic deformation. Once the material yields, it begins to strain … See more WebMechanical size reduction and separation.
