Basics

There are a number of units and scales commonly used to measure particle size. These either refer to average particle diameter measured in units of length, typically microns, or refer to a smallest mesh size through which the particles will pass. The following table sets out conversions between a variety of systems:   US MESH TYLER SCREEN BSS MESH MICRONS INCHES MILLIMETRES EXAMPLE 18 16 16 1000 0.0394 1.000   20 20 18 841 0.0331 0.841   25 24 22 707 0.0280 0.707 beach ...  Read more 

Agglomeration The clumping of powder particles bound together into clusters containing trapped air.   Air Classification Air classification is a technique by which dry powders of mixed particle size are separated into two distinct fractions, one above and one below a definite cut point. This is achieved by exploiting the differential forces acting upon particles of different size and mass within an air flow system. Different techniques can be required to achieve this depending on the material and particle sizes involved and British Rema has a full range of classifier options available to meet a wide range of operating ...  Read more
