Core Design Principles Given the characteristics of plastic blue barrels—thick walls and rigid texture—the drive system adopts a high-power motor paired with a reducer to deliver low-speed, high-torque power. This design minimizes blade wear caused by high-speed operation, while easily tearing through thick-walled plastic. It also prevents equipment jamming due to excessive load, meeting the requirements of continuous industrial operation.
Cutting System
The moving blades are made of high-hardness, wear-resistant alloy material and arranged in a helical pattern on the main shaft, which can directly shred plastic barrels.
The fixed blades are mounted on the inner side of the machine's knife box, and the included angle formed with the moving blades ensures that the plastic barrels can be shredded into small particles.
The gap between the blades is adjustable, which can be tailored to the required particle size of the output material and also adapted to plastic materials of varying thicknesses.
The machine body structure is designed to prevent material spillage during the shredding of plastic materials and also collect the fine particles generated in the process.
Feeding Stage
The plastic blue drums to be processed are fed into the feed inlet of the single-shaft shredder via the conveyor belt.
Crushing Stage
When plastic blue drums enter the shredding knife box, the hydraulic system pushes them toward the main shaft for shredding, and repeatedly propels them to the main shaft of the shredder for further processing. Materials that meet the discharge specifications will be directly discharged through the screen (which can be customized according to the customer’s required particle size). Oversized materials that fail to meet the standards will be intercepted by the screen and remain in the knife box for repeated shredding until qualified.
