You get a lot of powder with larger deviation from the hammering. 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.
Dec 18, 2020 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.
Feb 04, 2020 Hammer mills generally have much higher throughput rates than roller mills, so you can produce more feed in less time.

Feb 28, 2010 Hammermills versus roller mills. When it comes to size reduction of principal feed ingredients, recent practice has been to use hammermills as the main grinding machines. This wasnt always the case. In the early days of compound feed milling, when raw materials were homegrown and power sources were either wind or water, the effort needed to grind or flake cereals into a form where animal uptake was optimized dictated that roller milling
Over time, roller mills have been used to perform a wide variety of tasks related to the production of animal feeds. Hammer mills have traditionally been used to produce the finer grinds for pelleting and many mashes meal or non-pelleted feed applications as well. The hammer mill is a relatively simple machine and requires a fairly low degree of skill in regard to both the operation and maintenance.
