Technique Principle
The Tree Root Stump Crusher employs โโrotary high-torque cuttingโโ via a multi-blade rotor driven directly by hydraulic/motor power. Whole stumps enter an โโoffset rotating hopperโโ with internal feed teeth that progressively guide material into the cutting chamber. An โโintelligent anti-jam systemโโ 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: โโProcesses entire stumps (โค700mm diameter)โโ directly into biomass chips using multi-blade rotor torque. โโSaves 70% labor/timeโโ by replacing splitters + chippers with one automated operation โ ideal for forestry waste recycling.
โโPatented hopper reversal technologyโโ: Offset rotary feed hopper with internal teeth + frequency-controlled sensors auto-reverse on overload. โโGuarantees zero jamsโโ even with knotted roots or embedded debris, maximizing uptime.
180ยฐ hydraulic tank-tiltingโโ exposes rotor/blades in <2 mins. Combines with โโmodular blade cartridgesโโ for on-site replacements without disassembly. โโReduces service downtime by 60%โโ โ critical for 24/7 biomass plants.
Key Features
Volume Revolution
Achieve โโ90-95% volume reductionโโ 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 efficiencyโturning waste into compact, transport-ready biomass.
Absolute Mobility
Highway-ready tiresโโ, integrated โโtow hitchโโ, and a โโ360ยฐ swivel dischargeโโ enable instant deployment anywhereโmountains, highways, or urban roads. No setup required: just arrive, connect, and shred. The diesel engineโs protective housing ensures durability while allowing unrestricted operation in remote terrain without burning bans or grid power dependency.
Diesel Dominance
Powered by a โโturboforce diesel engineโโ with hydraulic load-sensing, it crushes even dense hardwoods non-stop. Built for 24/7 forestry workloads: โโ600mm cutting bladesโโ, 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
- โโFeeding Phaseโโ
โ Stumps/logs are hydraulically grabbed and loaded into the โโoffset rotating hopperโโ. Internal feed teeth actively position material toward the crushing zone without manual intervention. - โโAnti-Jam Detectionโโ
โ Sensors monitor rotor torque. If overloaded (e.g., knotted roots), the hopper โโautomatically reverses rotationโโ via frequency control, dislodging jammed material before resuming feeding. - โโPrimary Crushingโโ
โ Material enters the โโmulti-blade rotor chamberโโ spinning at high torque (2100-2800 RPM). Rotor blades shear/impact stumps against hardened anvils into coarse fragments (50-150mm). - โโRecirculation & Sizingโโ
โ Partially crushed fragments fall onto a โโsloped screenโโ. Oversized pieces slide back into the rotor path via gravity for re-crushing; sub-screen fragments proceed to discharge. - โโOutput Calibrationโโ
โ Final material passes through โโinterchangeable screensโโ (30/50/70/100mm). Centrifugal force ejects uniformly sized biomass chips via the conveyor chute. - โโMaintenance Cycleโโ
โ Post-operation, hydraulic cylinders tilt the entire โโrotor tank 180ยฐโโ in <2 minutes, exposing blades for inspection/replacement without dismantling.

Core Advantages
Rotorโ
Precision-Engineered Hammer Designโโ: Forged alloy blades with staggered tooth geometry maximize shear-impact efficiency on dense stumps. โโDynamic balancingโโ (ISO 1940 G2.5 standard) ensures vibration-free operation at 2,800 RPM, extending bearing lifespan by 40% under heavy loads.
โโFeed Hopper
Optimized Flow Geometryโโ: Steep-sided, trapezoidal design ensures material autoloading into crushing zone. Internal wear plates (400 HB hardness) resist abrasion, while โโintegrated material deflectorsโโ prevent bridging – sustaining 98% continuous feeding efficiency for bulk stumps/logs.
Chain-Driven Infeed System
Anti-Jam Power Transmissionโโ: Dual-strand 22mm pitch chains coupled with sprocketed push plates provide โโpositive displacement feedingโโ. Sealed lubrication ports and torque limiters eliminate slippage, reducing chain fatigue by 25% vs. belt systems in high-shock applications.
Oversized Feed Openingโ
Hydraulic Maintenance Revolutionโโ: 700ร700mm feed throat accommodates whole stumps (รโค680mm). โโDual-action hydraulic rams tilt the entire crushing chamber 110ยฐ in 90 secondsโโ, enabling direct rotor access without disassembly – cutting service downtime by 70%.
PLC Control Systemโ
โโSmart Automation Coreโโ: Industrial-grade PLC with โโoverload pre-warningโโ (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 Screenโ
Granularity Precision Controlโโ: Interchangeable chromium-manganese steel screens (30/50/70/100mm) feature โโtapered hole profilingโโ to prevent clogging. Quick-release cam locks allow screen swaps in <5 minutes, ensuring consistent biomass sizing (ยฑ3mm tolerance).
