Renn Roller Mills 

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

RENN’s unique chill-cast rolls are our latest advancement in rolling technology. These centrifugally-poured, chill-cast rolls give you the wearability of cast rolls with the enhanced serviceability of removable shafts and end plates. Our innovative design team has developed an alternative to the conventional solid core cast roll; incorporating a 16” diameter casting that has a 3” thick sidewall. This new roll has the performance and wearability of chill cast rolls with the advantage of a lower power requirement and better economics as you are no longer paying for the unusable part of a roll; the center core.

The RENN Roller Mill design is proven for operator efficiency and 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. After thousands of tonnes of work the rolls can be pulled for service in minutes due to RENN’s tip up top hopper and split frame design, regrooved and quickly reinstalled for thousands of tonnes of more trouble free rolling. The performance of the RENN Roller Mill is second to none. The 16” diameter RENN Roller Mill will always outperform any small diameter roller mill.
