ATEX-certified explosion-proof and Hazardous waste compliant four shaft shredder

The four-shaft shredder is a high-performance industrial machine engineered for efficient size reduction of complex, mixed, or challenging solid materials. Featuring four independent rotating shafts with interchangeableconfigurations, it excels in processing metals, plastics, wood, tires, and municipal solid waste (MSW). This system combines precision shredding with robust construction to deliver uniform particle sizing, high throughput, and low operational costs.

• Upper Shafts: Equipped with spiral-cutting blades to grip and pre-shred large or flexible materials (e.g., plastic films, wood).

• Lower Shafts: Fitted with heavy-duty hammers to crush fragments into uniform particles against adjustable screens.

• Differential Speed Control:

• Upper shafts: 30–60 RPM (fast rotation for material feeding and initial tearing).

• Lower shafts: 15–30 RPM (slower rotation for compression and densification).

• Interchangeable Screens: Perforated (5–50 mm) or slotted (10–100 mm) options for precise particle size control.

• Hydraulic Actuation: Quick screen adjustment or replacement without manual tools.

• Auto-Reverse Function: Reverses shaft rotation automatically to clear jams, preventing motor overload.

• Load Sensors: Detect abnormal pressure and trigger emergency stops.

• Dust Suppression: Integrated ports for connecting dust collectors, reducing emissions during plastic/fiber processing.

• High Efficiency: Single-pass processing reduces labor and energy costs.

• Versatility: Handles mixed materials (e.g., metal-plastic composites) without frequent adjustments.

• Low Maintenance: Replaceable knives and wear-resistant liners extend service life.

• Safety Compliance: Fully enclosed design with emergency stop buttons and safety interlocks.

• Daily: Clean knife edges, inspect bearings, and check lubrication.

• Weekly: Test auto-reverse functionality and sensor responsiveness.

• Monthly: Measure blade wear (replace when >20% thinning).

• Annual: Align shafts, replace worn seals/bearings, and repaint corrosion-prone areas.

• Resource Recovery: Diverts up to 95% of waste from landfills, converting it into reusable commodities.

• Cost Savings: Reduces disposal fees by up to 70% while generating revenue from recycled materials.

• Sustainability: Energy-efficient design complies with ISO 14001 and global emissions standards.

• Knife Materials: D2 tool steel, carbide coating, or Tungsten carbide for extreme durability.

• Automation Integration: PLC control, remote monitoring, and AI-driven load optimization.

• Mobility: Skid-mounted or tracked versions for on-site processing.
