Renn Mill Center Inc.

Auxiliary Roller Mills



The RENN Auxiliary PTO Roller Mill is specially designed to allow operators to run a Roller Mill and Bagger with one tractor. This convenient way of rolling and bagging grain increases harvest efficiency by reducing manpower requirements, eliminating tractor needs, and saving on fuel consumption. The unique inline system will also allow you to power a Forage Blower and process grain up into upright storage with a single tractor, again saving time and money. For added flexibility, the RENN Auxiliary Roller Mill can also be used as an independent Roller Mill, and can process dry and high moisture grains directly into bunkers. Auxiliary PTO Roller Mills are available with self-contained or tractor hydraulics, gearbox reduction PTO output, and 1:1 or differential drive Roller Mills.

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.

Auxiliary Mill Power Option

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.
