Get the Grain Processing Quality You Want with RENN Roller Mills

RENN Roller Mills can be tailored to meet the needs of any grain processing application.

We offer two different types of rolls – steel or cast; multiple roll configurations ranging from 4 to 15 grooves per square inch depending on the particle size you require – and a variety of input and discharge options, including our Elevator Discharge or Crimper Mill, Blower Discharge Mill, Conveyor Discharge Mill, Electric Roller Mill, and Auger Discharge Mill. We offer so many choices that we can build a Roller Mill that is perfectly designed to consistently meet the specific grain processing needs of your dairy or beef herd.

Whether you need a coarse crack or a fine grind, our Roller Mills consistently produce the high-quality feed that farmers have come to expect from RENN. The more consistent the feed is, the more consistent the animal will convert it.

Maximise Productivity

RENN Roller Mills have a proven record of excellence in the grain processing industry, maximising productivity while providing durable, consistent performance and easy serviceability.

For 60 years, the heart of the RENN Roller Mill has been its precision-machined 16″ diameter rolls, which provide more grain rolling area per revolution compared to other brands of roller mills with smaller diameter rolls. RENN Roller Mills save time and money year after year by rolling more grain per hour with less horsepower.

RENN’s unique, centrifugally poured, chill-cast rolls represent its latest advancement in rolling technology, offering the long-wearing durability of cast rolls with the enhanced serviceability of removable shafts and end plates.

Lower Power Requirement

Unlike conventional, solid-core cast rolls, our 16” diameter casting with a 3” thick sidewall provides the performance of chill-cast rolls with the advantage of a lower power requirement and better economics, as you are no longer paying for the unusable centre core of the roll.

The RENN Roller Mill design ensures operator efficiency and time-saving serviceability. The RENN worm drive roll adjustment allows for easy roll gap adjusting while the RENN leaf spring holds the rolls in place for maximum rolling capacity. The rolls can be pulled for service in minutes due to RENN’s tip-up top hopper and split frame design, making it fast and easy to re-groove and re-install them, for thousands more tonnes of trouble-free rolling.
