Shredder Crusher Machine
Shredder Crusher Machine Product Definition and Applications
Featuring dual-shaft counter-rotating cutters, Shredder Crusher Machine originated in Europe in the 1980s as an industrial pre-crushing solution. It uses shearing and tearing to break plastic barrels, bottles, woven bags, rubber tires, wood, electronic scrap, and thin metal sheets into uniform pieces for subsequent sorting, washing, or granulating. The equipment processes up to 12 waste categories including metal, plastic, rubber, and wood, with a maximum feed size of 2800mm and output from 3 to 30mm.
Shredder Crusher Machine Core Structure and Working Principle
This equipment consists of a feed hopper, dual-shaft crushing chamber, dual-motor drive, PLC panel, and discharge conveyor. The cutter system uses 42CrMo alloy steel shafts with D2 blades. Two motors drive the shafts in opposite directions at different speeds, creating shearing and tearing forces. This low-speed high-torque design enables Shredder Crusher Machine to handle materials of varying hardness.
Shredder Crusher Machine Technical Specifications and Model Selection
Parameters based on industry standard data:
| Model | Spindle Power | Speed | Capacity | Applicable Materials |
|---|---|---|---|---|
| Model 800 | 22kW×2 | 9-12r/min | 1.5-2t/h | Plastics, rubber, e-waste |
| Model 1200 | 45kW×2 | 9-12r/min | 2.8-3.3t/h | Plastics, rubber, thin metal |
| Model 1400 | 75kW×2 | 9-12r/min | 5-6t/h | Metal, auto shells, tires |
| Model 1600 | 90kW×2 | 9-12r/min | 7.5-8.5t/h | Mixed waste, bulky metal |
Dual-shaft shredders typically process 500 to 30,000 kg/h at 380V with 90-315kW power. Model selection depends on material type and throughput.
Three Core Performance Features of Shredder Crusher Machine
The product offers three main features derived from its design and control system. The equipment operates with low-speed high-torque for reduced noise and effective hard material processing. The modular blade design and PLC intelligent control system enable cost-effective maintenance and overload protection. The structural frame maintains stability through stress-relief treatment and precision manufacturing.
Low-speed high-torque operation keeps noise below 85 dB, with some models as low as 75 dB, and handles hard materials easily.
Modular blade design supports independent replacement, potentially reducing maintenance costs by 40%. The PLC system includes overload protection with auto-reverse when torque exceeds 120% of set value.
Structural stability is achieved through stress-relief treatment, with frame deformation under 0.2mm after 3,000 hours of continuous operation. Users can rely on Shredder Crusher Machine for long-term production consistency.
Three Material Categories Processed by Shredder Crusher Machine
The unit processes materials in three categories based on their physical properties and processing requirements. Plastics and rubber materials are suitable for shredding due to their toughness and elasticity. Metals and electronic waste require higher cutting force and wear-resistant blade configurations. Other materials such as wood, agricultural waste, and medical waste have varying density and moisture content that affect processing efficiency.
Plastics and rubber include PE pipes, PP bags, PET bottles, HDPE drums, PVC pipes, tires, and rubber scrap.
Metals and electronics include auto shells, aluminum, engine casings, steel sheets up to 5mm, TV casings, and circuit boards.
Other materials include wooden pallets, agricultural straw, medical waste, and municipal solid waste. It adapts to each category with appropriate blade settings.
Three Scheduled Maintenance Checks for Shredder Crusher Machine
Regular maintenance extends the service life of this equipment through three essential checks. Bearing temperature monitoring prevents seal aging and component failure. Blade wear inspection ensures consistent shredding efficiency and product quality. Bolt retorquing maintains structural integrity and prevents vibration-related loosening.
Check bearing temperature every 8 hours; keep below 65°C, stop if over 75°C.
Inspect blade wear every 200 hours; replace or sharpen when wear exceeds 30% of original size.
Retorque all bolts to 280 N·m every 500 hours to prevent loosening from vibration. Following these steps keeps Shredder Crusher Machine in optimal operating condition.
Frequently Asked Questions About Shredder Crusher Machine
How long do blades last on Shredder Crusher Machine?
Blade life depends on material hardness. 9CrSi steel lasts 800-1,200 hours; D2 steel can exceed 1,500 hours.
How to clear a jam in Shredder Crusher Machine?
Jams usually result from overfeeding or oversized material. Press the reverse button, clear the blockage, then resume uniform feeding.
What causes abnormal noise in Shredder Crusher Machine?
Noise often comes from bearing issues, loose blades, or hard materials. Stop and inspect bearing lubrication and blade tightness.
What information is needed to select a Shredder Crusher Machine?
Provide material type, form, target output size, and hourly capacity. Choose the model based on your specific material and throughput.
