The term "millwork" is used by professionals to refer to any construction material that was made in a sawmill and built into the home, like wall and door trim. Materials like flooring are not considered to be millwork, as millwork is typically more decorative than structural. The definition of millwork is broad.

ing (, plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (, plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill.

Prater's Air Classifying Mills operates by using the combination of twostage closed circuit grinding/milling with an interstage air classifier all in one convenient unit. The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size.

which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (1050) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from to 2mm, but run at a very high rpm (roughly ).

The Classifier is able to achieve a precise, predictable, and extremely sharp separation at a high solids loading. The Model 100 Classifier system is ideal for the production of lab size samples, product development and/or small quantity production. The larger Model 250 and Model 500 offer precision classification at higher production rates.

Dynamic air classifiers. A dynamic air classifier uses the principles of elutriation, drag force, and centrifugal force to separate materials into coarse and fine fractions. A dynamic air classifier can classify a wide range of materials with particle sizes from 3 to 100 microns and can operate either inline or offline, depending on the process.
