Product Overview
The Efficient Wood Chipper Shredder is a specialized auxiliary equipment for organic fertilizer production, designed to process agricultural and forestry waste into fine particles that accelerate composting. It adopts a horizontal dual-chamber structure—combining a chipping chamber (for large branches) and a shredding chamber (for soft materials)—to handle diverse raw materials, from tree branches (up to 150mm diameter) to straw, leaves, and garden trimmings. The crushed materials (5-20mm particle size) have a larger surface area, which promotes microbial activity and shortens composting time by 30% compared to unprocessed waste. The machine also features a built-in conveyor belt (length 2m) that transports crushed materials directly to compost tanks, reducing manual material handling.
Product Features
Dual Crushing Mechanism: The chipping chamber uses a high-speed rotating blade (1200 rpm) made of SKD11 alloy steel to cut thick branches into 30-50mm chips, while the shredding chamber employs a hammer mill design (8-12 hammers) to refine chips into 5-20mm particles. This two-stage process ensures uniform particle size regardless of material hardness.
High Processing Capacity: Shreds 2 tons per hour for hardwood branches (e.g., oak, maple) and 5 tons per hour for soft materials (e.g., wheat straw, pine needles), with adjustable feed rate via a variable-speed conveyor (0.5-1.5m/min) to prevent overloading.
Low Waste Generation: Produces uniform particles (5-20mm) that decompose 30% faster in compost piles, as the small particle size allows better air circulation and moisture retention. Less than 2% of the input material is left as unprocessed waste, minimizing material loss.
Safety Protection: Equipped with multiple safety features, including an emergency stop button (both on the control panel and near the feeding hopper), an overload protection system (automatically stops the machine if torque exceeds 150% of rated value), and a safety grille on the feeding hopper (prevents hands or large debris from entering the chamber).
Applications
Organic fertilizer plants using agricultural and forestry waste as auxiliary materials, such as mixing crushed branches with animal manure to balance carbon-nitrogen ratio (C/N ratio) in compost (ideal C/N ratio: 25-30:1).
Nurseries and farms recycling garden waste (e.g., pruned branches, fallen leaves) into compost mulch, which improves soil structure and reduces the need for chemical fertilizers.
Biogas plants processing lignocellulosic materials (e.g., corn stover, sugarcane bagasse) into fine particles that enhance methane production efficiency by 15-20%.
Urban green waste treatment centers that convert park trimmings, street tree pruning, and municipal green waste into organic fertilizer raw materials, supporting circular economy initiatives.
FAQ
Q: What moisture content is suitable for raw materials?
A: Optimal moisture content ranges from 20-40% for efficient shredding. Materials with moisture ＜20% are too dry and may generate excessive dust, while moisture ＞40% can cause clogging in the shredding chamber. A moisture meter is included with the machine to help operators monitor raw material conditions.
Q: Can it process hardwood branches?
A: Yes, it handles hardwood branches up to 150mm in diameter with its high-hardness chipping blade (HRC 58-60). For extremely hard wood (e.g., teak), pre-soaking the branches in water for 24 hours softens the fibers and reduces blade wear.
Q: How often to replace the blades?
A: Blades last 300-500 working hours for softwood and 150-200 working hours for hardwood. The machine’s blade replacement design allows for easy access—blades can be removed and replaced with standard tools in ＜30 minutes per blade.
Q: Is there a dust control system?
A: A optional cyclone dust collector is available, which captures ≥90% of dust generated during shredding. This is recommended for indoor operation or regions with strict air quality regulations (e.g., EU, North America).
