A single-shaft shredder crushes lump materials through a systematic process. First, materials like plastic blocks or wood chunks are fed into the hopper, entering the crushing chamber. Driven by a motor, the shaft with specially designed blades rotates, interacting with fixed counter blades. The blades’ sharp edges and geometric design—serrated or spiral—create shearing and tearing forces, grabbing materials into the gap to break large lumps into smaller pieces. As crushed materials move along the shaft, secondary crushing occurs via repeated impacts between blades and the chamber wall, refining particles. The discharge system then expels the processed materials. This efficient mechanism, relying on mechanical force combination, ensures lump materials are reduced to desired sizes for recycling or further use.
