Abstract

The invention is used to grind bark, feed, plant stalks and other fibrous materials. The purpose of the invention is to increase productivity and improve quality due to uniform grinding. At an angle α to the working surface of the rollers 1 with teeth is mounted on the frame 4 a clamping mechanism with cutting discs 7. The clamping mechanism is equipped with an automatic adjustment 8 of the clamping force. During the rotation, the last roll 1 is equipped with a counter-knife 9. Raw materials for grinding are cut by the disks 7 from above, captured by the teeth of the rollers 1 and crushed by the counter-knife 9. With an increase in the mass of the raw material, the carpet thickness increases, the pressing force of the raw material with the cutting force increases. the sharp teeth of the rollers 1. The crushed raw material enters the receiving device. 4 il.
