This modular system combines hydraulic precision controls with adjustable roller configurations to process logs ranging from 200–600mm in diameter and 2–6 meters in length, achieving ≥95% debarking efficiency across softwoods, hardwoods, and even frozen logs. Its user-configurable design allows quick adjustments for specific production needs, minimizing downtime during shifts between log types or sizes, making it ideal for facilities handling mixed wood sources.
Parameter | Value |
Log Diameter Range | 200–600mm |
Log Length Range | 2–6 meters |
Debarking Efficiency | ≥95% |
Throughput | 10–12 tons/hour |
Power Consumption | 27.5kW (peak) |
Noise Level | ≤85dB |
The system’s adjustable pressure rollers deliver precise force—ranging from 500–2000N—tailored to log characteristics: higher pressure for dense hardwood barks (e.g., oak) and lower pressure for softwoods (e.g., pine) to prevent wood fiber damage. Its wolf roller design features carbide-tipped teeth arranged in a helical pattern, ensuring consistent contact across the log surface and efficiently removing even deeply embedded bark, such as that found on eucalyptus logs with rough outer layers.
Designed for versatility, the debarker features quick-release tooling that allows operators to swap between standard and heavy-duty rollers in ≤30 minutes. This flexibility supports seamless transitions between green logs (high moisture content) and dry logs (prone to brittle bark). Customizable conveyor interfaces with adjustable height and speed settings ensure integration with existing production lines, including veneer peelers, log stackers, and sorting systems, reducing retrofitting costs.
A PLC with HMI interface serves as the system’s nerve center, storing up to 50 debarking recipes programmed for specific log species, diameters, and moisture levels. Operators can recall recipes with a single touch, eliminating manual calibration time. A bark thickness sensor mounted at the entry conveyor continuously monitors incoming logs, adjusting roller speed (5–15 RPM) in real-time to maintain optimal debarking pressure—a critical feature when processing mixed batches.
Plywood Mills: Prepares logs for veneer peeling by removing bark and smoothing outer surfaces, reducing blade wear in downstream peeling operations.
Sawmills: Processes softwood and hardwood logs for lumber production, ensuring clean surfaces that simplify grading and reduce planing time.
Biomass Energy Plants: Separates bark from wood fiber, creating a consistent fuel source for boilers while producing clean wood chips for secondary processing.
Recycling Centers: Debarks reclaimed logs from construction waste, preparing them for reuse in furniture manufacturing or composite board production.
Q: How does the hydraulic system adapt to frozen logs, which have harder, more brittle bark?
A: The system detects frozen bark via moisture sensors and increases roller pressure by 30% while reducing speed by 20%, allowing the carbide teeth to penetrate and remove frozen layers without fracturing the underlying wood.
Q: Can it process irregularly shaped logs, such as those with curves or tapers?
A: Yes. The roller system features independent suspension that adjusts to log contours, maintaining consistent pressure across tapered sections and ensuring uniform debarking even on highly irregular logs.
Q: What maintenance tasks are required to keep the debarker operating efficiently?
A: Routine maintenance every 200 operating hours includes inspecting roller teeth for wear, checking hydraulic fluid levels, and cleaning the bark thickness sensor. Annual servicing involves replacing hydraulic filters and calibrating pressure settings.
Q: Is the system compatible with automated log feeding systems?
A: Yes. It integrates with robotic log loaders and conveyor-based feeding systems, supporting fully automated production lines with minimal operator intervention.
