Technique Principle
The Tree Root Stump Crusher employs rotary high-torque cutting via a multi-blade rotor driven directly by hydraulic/motor power. Whole stumps enter an offset rotating hopper with internal feed teeth that progressively guide material into the cutting chamber. An intelligent anti-jam system reverses hopper rotation upon overload. Crushed material is gravity-screened through interchangeable meshes, delivering uniform biomass output without pre-processing. Hydraulic tank-tilting enables rapid maintenance access.

Key Features
Eliminates pre-cutting: Processes entire stumps (≤700mm diameter) directly into biomass chips using multi-blade rotor torque. Saves 70% labor/time by replacing splitters + chippers with one automated operation – ideal for forestry waste recycling.
Patented hopper reversal technology: Offset rotary feed hopper with internal teeth + frequency-controlled sensors auto-reverse on overload. Guarantees zero jams even with knotted roots or embedded debris, maximizing uptime.
180° hydraulic tank-tilting exposes rotor/blades in <2 mins. Combines with modular blade cartridges for on-site replacements without disassembly. Reduces service downtime by 60% – critical for 24/7 biomass plants.
Key Features
Volume Revolution
Achieve 90-95% volume reduction by blasting wood chips directly into transport trucks via the discharge chute. This eliminates manual loading labor and slashes hauling costs by maximizing payload capacity. Fewer trips mean reduced fuel consumption, lower emissions, and immediate cost efficiency—turning waste into compact, transport-ready biomass.
Absolute Mobility
Highway-ready tires, integrated tow hitch, and a 360° swivel discharge enable instant deployment anywhere—mountains, highways, or urban roads. No setup required: just arrive, connect, and shred. The diesel engine’s protective housing ensures durability while allowing unrestricted operation in remote terrain without burning bans or grid power dependency.
Diesel Dominance
Powered by a turboforce diesel engine with hydraulic load-sensing, it crushes even dense hardwoods non-stop. Built for 24/7 forestry workloads: 600mm cutting blades, real-time engine monitoring, and industrial-grade chassis guarantee uninterrupted processing regardless of branch size or moisture. Ideal for high-volume clearance projects demanding zero downtime.

Application Scenarios
Working Principle
- Feeding Phase
→ Stumps/logs are hydraulically grabbed and loaded into the offset rotating hopper. Internal feed teeth actively position material toward the crushing zone without manual intervention. - Anti-Jam Detection
→ Sensors monitor rotor torque. If overloaded (e.g., knotted roots), the hopper automatically reverses rotation via frequency control, dislodging jammed material before resuming feeding. - Primary Crushing
→ Material enters the multi-blade rotor chamber spinning at high torque (2100-2800 RPM). Rotor blades shear/impact stumps against hardened anvils into coarse fragments (50-150mm). - Recirculation & Sizing
→ Partially crushed fragments fall onto a sloped screen. Oversized pieces slide back into the rotor path via gravity for re-crushing; sub-screen fragments proceed to discharge. - Output Calibration
→ Final material passes through interchangeable screens (30/50/70/100mm). Centrifugal force ejects uniformly sized biomass chips via the conveyor chute. - Maintenance Cycle
→ Post-operation, hydraulic cylinders tilt the entire rotor tank 180° in <2 minutes, exposing blades for inspection/replacement without dismantling.

Core Advantages
Rotor
Precision-Engineered Hammer Design: Forged alloy blades with staggered tooth geometry maximize shear-impact efficiency on dense stumps. Dynamic balancing (ISO 1940 G2.5 standard) ensures vibration-free operation at 2,800 RPM, extending bearing lifespan by 40% under heavy loads.
Feed Hopper
Optimized Flow Geometry: Steep-sided, trapezoidal design ensures material autoloading into crushing zone. Internal wear plates (400 HB hardness) resist abrasion, while integrated material deflectors prevent bridging – sustaining 98% continuous feeding efficiency for bulk stumps/logs.
Chain-Driven Infeed System
Anti-Jam Power Transmission: Dual-strand 22mm pitch chains coupled with sprocketed push plates provide positive displacement feeding. Sealed lubrication ports and torque limiters eliminate slippage, reducing chain fatigue by 25% vs. belt systems in high-shock applications.
Oversized Feed Opening
Hydraulic Maintenance Revolution: 700×700mm feed throat accommodates whole stumps (Ø≤680mm). Dual-action hydraulic rams tilt the entire crushing chamber 110° in 90 seconds, enabling direct rotor access without disassembly – cutting service downtime by 70%.
PLC Control System
Smart Automation Core: Industrial-grade PLC with overload pre-warning (vibration/torque sensors). 7″ HMI displays real-time RPM, temperature, and jam alerts. Auto-reverse sequencing triggered at 125% load threshold safeguards blades and transmission.
Calibration Screen
Granularity Precision Control: Interchangeable chromium-manganese steel screens (30/50/70/100mm) feature tapered hole profiling to prevent clogging. Quick-release cam locks allow screen swaps in <5 minutes, ensuring consistent biomass sizing (±3mm tolerance).
