Working Principle of a Plastic Shredder:Power Supply & Motor OperationThe shredder is powered by an electric motor, which is connected to a gearbox.The motor has forward and reverse switches to control the rotation direction of the shredder shafts (rotors).Dual-Shaft InteractionMost industrial shredders use two counter-rotating shafts (rotors) equipped with interlocking blades or "teeth."The gears in the gearbox transmit power to the main shaft, while a secondary gear system drives the opposite shaft to rotate in the reverse direction.Material FeedingPlastic materials (e.g., bottles, films, pipes, or scrap) are fed into the top hopper of the shredder.The rotating blades on the shafts grip and pull the plastic into the shredding chamber.Shredding MechanismAs the shafts rotate in opposite directions, the blades shear, crush, and tear the plastic through mechanical force:Shearing: Blades from each shaft interlock and cut the plastic like a pair of scissors.Crushing: The gap between blades compresses the plastic, breaking it into smaller pieces.Tearing: The rotational force pulls and rips flexible plastics (e.g., films) apart.The blades are staggered and arranged in a specific pattern to ensure multi-directional cutting (horizontal and vertical), enhancing shredding efficiency.Screen/Grille SeparationBelow the shredding chamber, a screen or grille with predefined hole sizes acts as a filter.Only pieces small enough to pass through the screen are discharged, while larger pieces are retained for further shredding.Discharge & CollectionThe shredded plastic particles (shreds) fall through the screen and are collected in a hopper, conveyor belt, or storage bin for subsequent processing (e.g., washing, melting, or granulation).Safety & Control SystemsMany shredders include overload protection (e.g., automatic reverse when jammed) and PLC (Programmable Logic Controller) systems to monitor and adjust speed, torque, and operation modes, ensuring safe and efficient performance.
