Introduction

In industrial waste processing and plastic recycling, the demand for high-capacity, reliable crushing solutions is paramount. The 3000 Series large plastic crushers meet this need with exceptional design, combining heavy-duty construction, intelligent controls, and customizable configurations to tackle even the most challenging materials. Whether processing 100+ tons of plastic pallets, car bumpers, or industrial waste daily, these crushers ensure consistent performance, minimal downtime, and superior output quality. This article provides an in-depth look at the 3000 Series, its core technologies, and how it transforms high-volume plastic processing.

1. Core Design Philosophy of the 3000 Series

1.1 Engineered for Massive Throughput

• High-Torque Performance: Designed to handle 3–8 tons/hour, depending on material type, with motors ranging from 200–500 kW to drive through tough, composite materials.
• Durability First: Heavy-duty steel frames (Q345B), wear-resistant shafts, and replaceable components ensure 24/7 operation in harsh environments.
• Smart Automation: Integrates PLC controls and IoT monitoring to optimize speed, torque, and energy use in real time.

1.2 Key Components Explained

1.2.1 Dual-Shaft Shredder (3000DS Model)

• Counter-Rotating Shafts:
  Two 300mm-diameter shafts with interlocking carbide teeth (speed difference 8–10%) generate 1,500 kN·m torque, ideal for oversized materials like 1200×1000mm pallets.
• Hydraulic Overload Protection:
  Sensors detect metal or glass contaminants, triggering automatic shaft reversal to prevent damage, reducing maintenance costs by 40%.

1.2.2 Precision Blade Crusher (3000BC Model)

• High-Speed Shearing System:
  24 SKD11 steel blades (rotating at 500 RPM) create a 0.5mm shear gap, producing uniform 8–30mm particles for rigid plastics like PET and ABS.
• Adjustable Screening Module:
  Quick-release stainless steel screens (304 材质) allow switching between 10–50mm mesh sizes in 15 minutes, adapting to downstream needs.

1.2.3 Claw Crusher (3000CC Model)

• Anti-Entanglement Design:
  12 pairs of Teflon-coated claws (2,800 RPM) with 12mm spacing tear soft films (PE/PP) without jams, handling up to 20% moisture content.
• Variable Frequency Drive (VFD):
  Automatically adjusts speed based on material thickness, improving efficiency by 25% for wet agricultural film.
