The board crusher allows direct feeding of waste plastic pallets, and is also suitable for large‑width plastic products such as pipes, plastic sheets and plastic doors & windows. Featuring moving‑fixed blade shearing structure and replaceable screen to control output size, it has excellent impact resistance. After metal impurities are removed, materials are fed directly into the machine. Repeated shearing and impact take place inside the crushing chamber. Plastic flakes conforming to screen size discharge from the bottom, and collected flakes can go through washing and separation to get recyclable plastic raw materials.
