Double-shaft primary shredder is used for the size reduction of large materials and solid waste pre-shredding, with shearing, chopping, tearing, and pressing. Engineered to perform durability and minimize maintenance costs, our double-shaft primary shredders can easily handle complex mixed solid waste, unsorted household garbage, construction debris, or industrial waste. The shredders designed by our company boost operational efficiency and processing capabilities.

Equipment Configuration

Rotating Blades: Featuring one forward-facing and two backward-facing knife teeth, these blades rotate closely around the fixed blades. A 160mm gap between each set of fixed blades on the shredding table allows sand, soil, gravel, and small metal fragments to pass through easily, significantly reducing wear on the shredding table. Depending on the type of waste, up to 90% of the crushed material achieves a particle size below 200mm.

Central Lubrication System: Automatically manages lubrication of the main bearings to ensure smooth operation and extended component life.

Power Units: Consists of a motor, hydraulic system, oil cooler, and PLC control unit. The shaft speed ranges from 16 to 41 rpm, with optional simulated shaft speed control available.

Hydraulic System: Equipped with variable pumps featuring power control, integrated supply pumps, and hydraulic motors mounted on each shaft. This dual hydraulic system delivers maximum processing power and reliable performance.
