The modification in design of the hammer mill focused on the hammer pattern and arrangement; whereas the performance analysis was conducted based on the average particle of bambara nut, cassava, and maize samples. The average particle sizes of the samples were compared to those produced with standard hammer mill and burr mill. The result shows that although the three grinders had no course (C ...

The hammer mill's functioning principle is straightforward. Fig. illustrates the principle (a). All that is required is the selection of a suitable engine, crushing hammers/knives, and the material to be crushed. It works on the basis of impact between the rotor's fastmoving hammers and the stationary powder bed.

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.
