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.
