A hammermill is one of several types of crushing machines, including impact crushers, jaw crushers, and cone crushers, that is manufactured for the purpose of processing raw materials to reduce them in size. In the crushing industry, there are two types of forces used to reduce the size of materials: impact forces and compression forces.

Typical dry hammer mills in wood pellet preparation have a throughput of 9 to 11 tons per hour using a 600 horsepower motor, but performance characteristics depend on the raw material quality. High-quality raw material, such as clean sawdust from a manufacturer's own sawmill, is so clean that hammers will virtually last forever.

Fitzpatrick Hammer Mills produce the smaller PSDs and are more suited to abrasive and difficult to mill products. They are the mill of choice when you need to precisely control the particle size reduction process. It is important to get the feed throat angle matching the material characteristics - a vertical inlet for fragile material or horizontal for fine grinds.

As noted, particle size reduction in a hammermill occurs as a result of the impact between a rapidly moving hammer and a relatively slow moving particle. The particle breaks and is accelerated towards the screen; depending on the particle size and angle of approach, it either passes through the screen or rebounds from the screen into the rapidly moving …

Hammer mills use a combination of impact, shear, and compression forces during size reduction, with the largest proportion due to the impact [11] [12] [13]. However, Hammer mill takes a longer time and high speed to produce fine particles (flour) which in turn consumes a lot of energy per kilogram of flour produced.

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.
