Evacuation options Once the material is reduced to the desired finished particle size and passed through the screen, there are two options for how it exits the mill. The method is determined by the material's characteristics. If the material is: How Does Pneumatic Discharge Work? It's all about the fan.

particle sizes for feeding. There are several facets which can affect the final particle size achieved using the hammermill. Traditionally, the most common method of changing the particle size is to exchange the size of screens for either a smaller or larger hole diameter. Screen changes lead to increased down time and loss of production within

Hammer milling parameters such as screen size, blade selection and rotor speed can be optimized for each application, depending on the equipment used. 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.
