The Right Materials Create the Best Roller Mills

We don’t cut corners when it comes to providing the industrial farming equipment you need. Our grain roller mills and electric mills are designed to be hard-working and long-lasting. You can depend on Automatic Equipment Manufacturing to provide feed processing mills that don’t require frustrating repeat maintenance and part replacement.

The Most Efficient Grain Processing Equipment for Livestock

Your livestock operation needs to achieve maximum efficiency to compete with the ever-increasing competition locally and globally. Automatic's industrial grain mills can help you achieve this in three ways:

Better Growth of Livestock

In a 2017 study of using an Automatic roller mill at the Beller Feedlot, we saw the real-world results our mill could deliver. Cows on this lot saw three pounds more growth per head. And when the beef was graded, the herd achieved 4.5% more Prime or Certified Angus grade. In addition, because the Automatic industrial grain mills could handle more different types and grades of grain, the feedlot could afford to buy more feed at a lower cost. And they saw a 1.88% higher feed conversion. 

Energy Efficiency

One of the outstanding efficiencies of Automatic industrial grain mills is that they require less energy. In fact, roller mills use as much as 85% less energy than hammer mills. With any quality of grain, you can count on using one-third less horsepower than with other mills. 

Time Efficiency

Time is money in your livestock operation, whether it's time you spend or hours you have to pay employees. An Automatic industrial grain mill can save you time. The high throughput of the mill means you don't have to spend as much time milling your livestock feed. 

Plus, the high-quality materials used in Automatic roller mills mean less downtime. The automatic hardened steel used for the rollers will function for longer and require fewer recorrugations. Plus, our machines are designed for easy maintenance so even when they're down, they aren't down for long.

Our Automatic 10K Electric mill is an outstanding machine. We use two one-thousand bushel dump pits. On our biggest day, we process 145,000 bushels through the mill at about 9000 bushels per hour with 25 to 28% moisture. I no longer dread high-moisture corn season.



Avoid Feed Waste &
Respiratory Ailments


Dust-free rolled grain will not be “windblown” out of the feed bunk. Your livestock will eat it all, and they will avoid respiratory problems cause by inhaling “powdered feeds.”


More Gain From Your Grain


More farmers are choosing Automatic, one of the most energy-efficient methods of processing all types of feed grains. Whether you are feeding beef, pork, dairy or poultry, you will get more from your grain with Automatic. Make 4 bushels do the work of five. and get more milk per cow, faster, more economical gains. All livestock thrives on rolled grain.


Improved Palatability & Digestibility
