Rotary Mills vs. Electric Mills

Updated: Jul 6

Determining What's Best for You - Rotary Mill or Electric Mill?

What should your farming equipment so for you and what tools best fit your needs and the size of your operation? Knowing the answers to these questions can help you avoid a mismatch match in business investments; avoid overbuying for your needs or purchasing equipment that can’t keep up with the pace at which you run your farming operation.

The team at Automatic Equipment Manufacturing knows our customers love to compare and contrast the machines we have available. After all, educating yourself on features and capacity is the best way to ensure you make the right choice for your needs. If you’re considering a rotary mill or an electric mill, read through the following to help make your decision:

Rotary Mills


These machines for processing grain come in a variety of styles and mechanisms for pulverizing grain. Rotary simply means revolving around a central axis, making a rotary mill a broad term that can incorporate rod mills, ball mills, and hammer mills. The idea is the same: using rotating components that crush kernels of grain – from corn and oats to materials for other uses, such as making cement and processing ore. Hammer mills, for example, are a popular type of rotary mill for agricultural professionals. These mills are versatile; you can change screens to successfully process different types of grain for your needs. Hammer mills operate at a high rate of speed and can help you generate the output you need to add pounds to your animals. You may find, however, that the grinding components of the hammer mill are more prone to wear and tear, and that this type of equipment is not recommended for fine grinding; the mill may over-process your preferred grain.

Roller Mills

As opposed to hammer mills, roller mills crack grains between rollers of varying size and distance to create the feed and quality and output you’re hoping for. Roller mills, like hammer mills, are adjustable for different grain types and desired crack for those materials. Because the roller mills created by Automatic Equipment Manufacturing are made with hardened steel, they are less prone to wear-down with prolonged use. Roller mills are dependable and can uniformly crack fine or coarse grain to your desired result.


Roller mills are prized for their ability to create uniformity with each batch. Particles are of the same size and quality each time, so you can be sure your livestock is getting the nutrition they need for adding pounds and supporting their health and wellness. Using a roller mill also helps to reduce waste and feed dust, producing reliable feed.
