Get Consistent Quality with RENN Roller Mills, Hammer Mills, and Bagger Mills
RENN understands that in grain processing, the end result is everything.
Whether you feed 200 cow/calf pairs, 60,000 beef cattle, or 1,000 dairy cows, RENN’s durable Roller Mills, Hammer Mills (Grinders), and Bagger Mills offer a flexible design that delivers consistent, high-quality feed for any type or size of livestock operation.

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 so 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.

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.
