PACKER's double-shaft shredders are designed to meet the needs of waste recycling of waste chemical barrels, waste plastics, waste tires and other plastic products. The shredded plastic materials can be directly recycled or further refined according to demand, which can effectively increase the bulk density of materials and reduce transportation costs.
PACKER's double shaft shredder is a new type of powerful rubber and plastic shredding equipment. The shredder drives two shredding knife shafts through two separate reducers. The equipment is equipped with a start, stop, reverse and overload automatic reverse control functions to complete the processing of materials safely and stably. It has the characteristics of low speed, high torque, and low noise.
2. working principle
After the material is fed into the hopper, it is caught and crushed by many (or dozens) cutter heads with special shapes. Plastic fragments are pulled down to the discharge port. Knives for cutting plastic are cleaned with side plates. Due to the shape of the disc, the material will be dumped.
3. Structure of double shaft shredder
1）Main body of shredder
The body of the double shaft shredder is welded with high-quality steel plates to eliminate stress, and it is machined and welded as a whole. At the same time, it is processed by a CNC machining center, which ensures high machining accuracy, prolongs the service life of the equipment, and ensures that the equipment can be shredded in high-hardness materials. The stability of the whole machine in the crushing operation.
2）Blade of shredder
The moving knife is made of special high-quality alloy steel forged blanks, which are processed by precision machining, heat-treated many times, and finally ground and washed. The blade has high hardness and good toughness.
The inner hole of the blade adopts an inner hexagon, which is closely fitted with the spindle. Different numbers of claw structures are distributed around the blade. When the spindle rotates, the claw structure completes the grasping effect of the material, ensuring that the material will not roll repeatedly. The thickness of the blade is customized according to the discharge requirements. The thicker the blade, the wider the width of the cut material, and the more the number of claws, the shorter the length of the material.
The cutter shaft is made of high-strength and heavy-duty special steel. The cutter shaft has been heat-treated many times and processed with high precision, which has good mechanical strength, strong anti-fatigue and impact resistance, and long service life. The overall structure is a hexagonal shape, which can more reasonably cooperate with the blade for powerful cutting.
4）Power frequency conversion system
Due to the large volume and high hardness of the shredded material, the whole machine has a large working load. In order to prevent the equipment from getting stuck and burning out the motor, the equipment adopts an electrified automatic system that automatically reverses, and supports forward rotation, reverse rotation, manual operation, etc. Equipment intelligent control system, automatic production, to ensure production efficiency.
