The Ultimate in Grain Processing Effeciency

Roll and Store Grain with a RENN Bagger Mill

You can roll and store high-moisture grain all at the same time with a RENN Bagger Mill for ultimate grain processing efficiency.

RENN Bagger Mills offer the same durability and advanced grain rolling technology of RENN Roller Mills, combined with the smooth and efficient grain bag loading capabilities of a RENN Grain Bagger. The RENN Bagger Mill allows you to roll and store high-moisture grain economically in 4', 5’, 6.5’, or 8’ diameter grain bags, while choosing from a full range of options to precisely match your grain processing needs.

Maximum Production with Less Horsepower

The heart of the Bagger Mill features precision-machined, dynamically-balanced 16” diameter steel rolls with large diameter removable shafts that provide maximum production with less horsepower. Rolls are available in steel and chill-cast. Roll configurations range from 4 to 15 grooves per square inch.

Rolling high-moisture grain prior to storage allows nutrients to become readily available and ensures high-quality silage feed is produced. 

Smooth, Efficient Loading and Storage

Over the past 15 years, RENN has developed a unique grain tunnel and loading system that allows for smooth and efficient loading and packing of high-moisture grain. Grain placement, hydraulic brake pressure, and loading pressure create a well-packed, consistent product.

RENN Bagger Mills are available in 24”, 30”, and 36” Roller Mill configurations and a 5’, 6.5’, or 8’ grain tunnel.
