Back to Basics Hammer Milling and Jet Milling Fundamentals
feed stream in hammer mills for grinding tough materials. However, liquid nitrogen is seldom used in jet milling opera-tions due to the swift heat exchange between the material and the grinding gas. The grinding gas heats up the super-cooled feed stream, and the material loses its brittleness when it absorbs this heat. Stickiness.

Jet mill working principle - Jet mill
Heavier oversized particles are held in the grinding chamber by centrifugal force, until micronized to a desired size. Feed particle size is critical, restricted by the size of the feed injector. For mills of 200-300 mm, the feed size can be a maximum of 1.5 mm. For smaller-size mills, the feed size is correspondingly finer.
Grinding considerations when pelleting livestock feeds
grinding in feed milling applications. Hammermills have traditionally been used to produce the finer grinds commonly used for pelleting and for many mash (meal or non-pelleted) feed applications as well. The hammermill is a relatively simple machine and requires a fairly low degree of skill in
FAO: Feed formulation
Fine-grind hammer mills can grind product to 90 to 95 percent minus 420 μm (Bortone, 2005) or at best 300 µm (Chamberlain and Bortone, 2006). After grinding, 95 percent of the feed ingredients should be less than or equal to 250 µm (Tan and Dominy, 1997) and for smaller shrimp, 150 to 180 µm (Chamberlain and Bortone, 2006).

The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.
