The typical particle sizes that can be achieved with hammer mills is a D 50 between 150 μm and 600 μm. Hammer mills tend to yield less than 25% of particles below 150 μm. Because the end particle size of a milled material is determined by the screen size used on the mill, it is possible to use very small screens to attempt to get smaller particles.
