2020-12-17 A roller mill can efficiently break down grain for livestock feed. Energy efficiency is especially pronounced in electric grain roller mills. In some situations, roller mills use 85% less energy to process grain than hammer mills. In the most common processing situations, though, the energy savings are likely 30-50%.

The most common grinders are the hammer mills and the roller mills. They have been applied to the task of particle size reduction or grinding in feed milling applications. Roller mills have been used in the processing of common feed materials for years.

A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less horsepower then a similar capacity hammer mill. A roller mill gets a more consistent grind and smaller deviation then a hammer mill by rolling the grain instead of hammering it.

2010-02-28 Roller mills simply “roll” or “crush” product between two revolving cylinders. This latter process has the distinct advantage of requiring considerably less power, although it is not possible to achieve the fineness of final grind through a roller mill that can be achieved through a hammermill.

2017-06-22 The response in the roller mill was fully expected, but the results with the hammer mill definitely were not. In fact, Gypsum ground to 700 microns with a hammer mill was better digested than Gypsum ground with a roller mill. Corn ground to 500 microns with a hammer mill was similarly digested as Gypsum ground with a roller mill.

2014-07-08 Curtis, the basic answer seems to be if you "lauter", a roller mill works well because the husk, of whatever grain, is left reasonably intact. A hammer mill will usually chop the husk into fine pieces which is OK for fermenting with the grain in the fermenter

2018-09-05 The Pin Mill, unlike the Hammer Mill, consists of a series of pin breakers hinged to discs in the grinding head where it delivers high-energy impact. Pin Mills use shearing and impact methods; however, with a faster tip speed of intermeshing pins when compared to a Hammer Mill. Centrifugal force brings the particle sizes to the grinding chamber’s periphery for collection or further ...

2014-07-11 The hammer mill relies heavily on the screen impact in order to reduce the size of the material to the desired granularity level. The roller mill simply “rolls crushes” the material between its two or more rotating cylinders.

Hammer mill configuration. The three basic types of hammer designs are: The stirrup or LFS hammer, the swing bar hammer and the rigid bar hammer. The stirrup hammer has the most surface area and is used at high speeds to produce the finest particle sizes. The swing bar hammer is used on materials that do not respond well to impact. Fibrous materials that need to be cut or shredded work well ...

Four-roller mills Four-roller mills have two sets of rollers. When using a four-roller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits. Flour is sieved out of the cracked grain, and then the coarse grist and husks are sent through the second set of rollers, which ...

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 the work is better than having two.
