The term "carpentry" refers to the process of constructing things with wood, while "millwork" refers to any wooden object created in a mill, which are usually more intricate wooden finishings and details. Millwork does not include flooring, sidings or ceilings. Another confusing term associated with carpentry and millwork is casework.

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.

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.

1. Introduction The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [ [1], [2], [3], [4] ].
