How to Improve Energy Efficiency in the Milling Process

by | Jan 7, 2020

Feed mills tend to produce thousands of pounds of animal feed every day, if not every hour. Powerful hammer and roller mills crush flour, wheat, and other grains to create animal feed, consuming large volumes of energy in the process. As the owner and operator of a feed mill, reducing your energy consumption can improve your operations in more ways than one. Not only will you reduce your utility bills and give a boost to your bottom line, but you’ll also improve the nutritional value of your animal feed.

Learn more about why it’s important to reduce your energy consumption and how it can improve your overall business model.


Energy is expensive. Your company or facility may spend thousands of dollars a year or more paying for gas or electricity. If you want to lower your business expenses, reducing energy consumption is a great way to save thousands of dollars a year.

Unfortunately, older hammer and roller mills aren’t known for their energy efficiency. They tend to produce a lot of heat and friction during the grinding process. All that excess heat and friction will raise your utility bills and may even damage your equipment over time, leading to costly repairs and equipment downtime. Excess heat and friction can also affect the nutritional value of your animal feed. Heat destroys important nutrients that could have otherwise gone to your animals.

Improving energy efficiency isn’t just about protecting the environment or reducing your monthly bills; it’s about keeping your animals healthy and making the most of your animal feed.


If you’re looking to reduce your energy consumption during the grinding process, it’s best to upgrade your grinding equipment. Consider investing in the Buhler Multi-Impact Hammer Mill, one of the most energy-efficient models on the market today.

When it comes to hammer mills, the conventional line of thought was always that the faster the hammer tip speed, the finer the particles, but this theory has proved false in recent years. Increasing the hammer tip speed increases heat and friction, but there are other ways to decrease the size of your particles.

Instead of traditional screens, the Multi-Impact Hammer Mill uses cutting plates to break up particles as they enter the grinding chamber. This moves particles through the mill much faster than they would with a traditional hammer mill, thus reducing heat and friction. The Multi-Impact Hammer Mill improves energy efficiency while giving you more control over the size and shape of your particles. Reducing heat and friction also improves the overall safety of your feed mill. Your commercial feed mill equipment won’t get as hot, reducing the chances of combustion.

All business owners should be concerned with limiting energy consumption. It saves money, improves the nutritional quality of your animal feed and overall mill efficiency. The Buhler Multi-Impact Hammer Mill will help you reach your energy goals without sacrificing the quality of your feed.
