Get the Grain Processing Quality You Want with RENN Roller Mills
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.
Maximize Productivity
RENN Roller Mills have a proven record of excellence in the grain processing industry for maximizing 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 are its latest advancement in rolling technology, giving you 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.
RENN Roller Mill Features
Elevator Discharge Mill / Crimper Mill
The optional RENN 40% Differential Drive has idler and driver rolls positively driven at two different speeds for optimal particle reduction or high moisture rolling. It is also self-cleaning to prevent plugging. RENN Roller Mills are available in PTO powered trailer or Electric Stationary models, and offer various input, power, and discharge options. PTO models have a minimum power requirement of 15 to 120 horsepower, while Electric Stationary units operate with a minimum power requirement of 5 to 50 horsepower.
