The Fitzpatrick Company pioneered the development of particle size reduction and forming technology, with the development of the Lab Compaction System, Contained Compaction System roll compactor and FitzMill, Fitzpatrick has been constantly evolving powder processing technology and in conjunction with Quadro developed the Scalable Lab System.

Fitzpatrick Hammer Mills produce the smaller PSDs and are more suited to hard 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.

The blades can be knife-edged for “cutting effet” or blunt-edged for more impact and aggressive particle size reduction.  A blade with reversible edges becomes truly versatile, being able to match any product requirement.

Typical applications are: coarse grinding and chopping of dry material, size reduction of wet material, de-lumping of agglomerated wet or dry material, pulverizing, solid blending, granulating compacted material, processing slurries and liquids, processing and conditioning wet and dry materials, pureeing and emulsifying.
