For similar-sized particles, bulk density of material ground on a roller mill will be about 5 to 15 percent less than material ground by a hammermill. Hammermills . Advantages: produce a wide range of particle sizes; work with any friable material and fiber; less initial purchase cost compared to roller mills;
Hammermills Advantages: produce a wide range of particle sizes work with any friable material and fiber less initial purchase cost compared to roller mills offer minimal expense for maintenance generally feature uncomplicated operation Disadvantages: provide less efficient use of
2010. 2. 28. In a hammermill, the screen-hole diameter controls the maximum finished particle size of any ground product. When using roller mills, there is no screen being used, and unless the product is sifted and the coarse fraction reprocessed, the resultant particle size is purely reliant on the miller’s skill in setting the roller mill effectively.
Roller Mills Versus Hammer Mills To provide grain in a more digestible form the hammer mill has been the traditional method in the past, the main reason being that they can be also used for hammering the roughage as well. So having one machine to perform all

Roller mills are on average 30% more energy efficient than hammer mills providing our customers energy savings (KimKoch, Hammer Mills and Roller Mills, Kansas State University, May 2002) Roller mills do not produce heat, as hammer mills do, which is
Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, and 6.4mm (0.25 inches) thick. For a rotor speed of about 3,600 rpm, hammers should be 15 to 20 cm (~ 6-8 inches long, 5 cm (~ 2 inches) wide, and 6.4 mm (0.25 inches) thick.
