A raw feed to a jet mill is usually, but not necessarily, the product of a mechanical mill such as a hammer, air classifying (ACM), or roller mill. Raw feed sizes vary from granular or flake to the low micron range. When selecting a desired feed to a jet mill, remember a finer raw feed will yield a finer product or a faster rate.
