Four-Shaft Shredder: High-Efficiency Solid Waste Processing Solution

The four-shaft shredder is a heavy-duty size reduction machine designed for shredding large, rigid, or mixed solid materials. It utilizes four rotating shafts with interlocking knives to efficiently tear, crush, and granulate materials. Ideal for processing metal scrap, plastics, wood, tires, and municipal solid waste (MSW), this equipment ensures high throughput, uniform particle sizing, and minimal downtime.

• Dual Rotating Shaft Systems:

• Upper Shafts: Equipped with spiral-shaped cutting blades to grab and pre-shred materials.

• Lower Shafts: Fitted with hammer-like blunt knives to pulverize and compress shredded material.

• Differential Speed Design: Upper shafts rotate faster (30–60 RPM) for feeding, while lower shafts operate slower (15–30 RPM) for crushing, optimizing energy use.

• Adjustable Screening System:

• Perforated screens (5–100 mm) control output particle size.

• Hydraulically actuated screens allow quick adjustment or replacement.

• Overload Protection:

• Auto-reverse mechanism prevents jams or damage from oversized/hard materials.

• Sensors detect abnormal loads, triggering emergency stops.

• Heavy-Duty Construction:

• Welded steel frame with reinforced bearings for durability.

• Replaceable abrasion-resistant liners extend service life.

1. Feeding: Materials enter via conveyor belts or feed hoppers.

2. Primary Shredding: Upper shafts’ spiral blades tear materials into smaller pieces.

3. Secondary Crushing: Lower shafts’ hammers pulverize fragments against the screening plate.

4. Sizing: Particles meeting the screen’s size pass through; oversized debris recirculates for further shredding.

5. Output: Uniformly shredded material discharges for subsequent sorting or recycling.
