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.
Hammer mill is easy to set up (install), dismantle, and clean up. Scaleup problems are minimum provided the same type of mill is used. Various types of feedstock can be handled using a screen of different sizes. Hammer mill occupies a small space. It is versatile,, speed and screen can be changed rapidly.
The full circle screen hammer mill gets its name from the 300 degree screen coverage of the rotor, while all other styles of hammer mills typically have closer to 180 degree coverage of the rotor. The larger the screen area, the greater the opportunity for the material to evacuate the mill.
Hammer Mills. Hammer mills process the grain using either a series of swinging or stationary steel bars (hammers) to grind the grain. In most hammer mills, the hammers force the grain against a screen until the grain is the desired size and passes through the screen, but newer "screenless" models can use airflow instead of a screen to sort the grain that is the desired size.
Find out how the Fitzpatrick Hammer Mill could be the solution to your particle size reduction needs by requesting our brochure today. Screen type and Rotor speed.

Controlling these factors can help ensure a successful milling process with minimal downtime.
Hammer mill screen maintenance is especially important if you are running abrasive or hard materials. The decision to replace your hammer mill screens will depend on several factors including the type of material you are processing, the wear life of your screens, and the frequency of use.
The conical mill used in this study was a Quadro Comil Model197S (Fig. 1 (a)).Following recommendations of the equipment manufacturer, the conical impeller was positioned as close as possible to the screen (Fig. 1 (b)).Two types of screens (Fig. 2 (a)), one with round holes, and another with a combination of round and grated holes, were used in this study.
The Hammer Mill. A hammer mill uses hardened steel rectangles — referred to as hammers — which spin centrifugally around a motordriven shaft inside of a screen. As the hammers pulverize the grain, it is forced through the screen. Overall, hammer mills tend to produce a finer grist. The benefit of hammer mills is that screens are available ...
