[0002] Roller shredder is a machine that uses the friction of the roller surface to bite the material into the crushing area, so that it is crushed by squeezing or splitting. When it is used for coarse crushing or needs to increase the crushing ratio, teeth or grooves are often made on the roller surface to increase the splitting effect. Roller shredders are usually divided into single-roller, double-roller and multi-roller shredders according to the number of rollers.
