Gruber Grain Technology - 55 years of experience in the construction of straw mills
Straw processing

The Gruber Straw Ripper is used to shred the straws. The surface of the stalk is broken open and the inside is exposed. As a result, the straw can absorb much more liquid due to its larger surface area. It thus has 6-10 times the absorbency of normal straw. The Gruber straw mill is available with sieves from 20mm to 50mm perforation.
The basic machine is the respective CCM maize mill (MM 2000, 3000 or 4000). The rotating parts of the Gruber straw mill are electronically balanced, which results in very smooth running. The straw mill is extremely stable and robust as well as insensitive to foreign bodies. Conversion to a CCM maize mill is possible.
