Back to Basics Hammer Milling and Jet Milling Fundamentals

hammer mills may also be able to process materials with low melting points for coarse grinding applications. Explosibility. The risk of dust explosions must be taken into account when a material is ground very fine in a milling process. Dust-laden air can give rise to devastating dust explosions. Unless the material is one of the few commonly known to present no dust explosion risk (a stable ...
