Product Overview
With a 98% peeling efficiency and low wood loss rate (<5%), the log debarker machine removes bark uniformly while preserving the underlying wood fiber for downstream veneer peeling or chipping. Its compact design and high throughput make it an essential preprocessing unit in poplar-focused plywood mills.
Product Advantage
Ring-Type Design: The rotary drum features spring-loaded blades made from high-carbon steel (HRC 58–60) that adjust to log irregularities, ensuring complete bark removal even for curved or knotty poplar logs. This design outperforms traditional drum debarkers, which often leave 5–10% residual bark on uneven surfaces.
Hydraulic Feeding: A variable-speed conveyor (0.5–2 m/min) handles logs of varying diameters (50–350 mm), maintaining consistent peeling pressure (10–30 kN) via pressure sensors. This reduces log slippage to <2% and minimizes surface damage to the wood fiber.
Continuous Operation: The machine processes 10–30 tons of logs per hour, with a 15-second cycle time for individual logs. Its open-chamber design allows simultaneous feeding and discharging, supported by a hydraulic log pusher that ensures steady flow-ideal for large-scale plywood mills with daily log intake of 100+ tons.
Low Energy Consumption: A 7.5 kW motor drives the drum, consuming 30% less electricity than comparable models (0.5 kWh per ton of logs processed). The compact design (5.6 x 2.2 x 1.8 meters) saves floor space, while a built-in dust collection system reduces airborne particles by 90%.
Wear-Resistant Components: The drum and blades are coated with tungsten carbide (thickness 0.5 mm), extending their lifespan to 10,000+ hours of operation-twice the longevity of standard steel components. Replacement parts are interchangeable and cost-effective, with a global supply chain for quick delivery.
User-Friendly Interface: A touchpad control panel allows operators to adjust peeling intensity (3 levels) and conveyor speed with minimal training (typically <1 day). The machine also includes self-cleaning mechanisms (brush rollers and air blowers) to prevent bark buildup in the drum, reducing manual cleaning time by 80%.

Applications
Plywood Production
Prepares poplar logs for veneer peeling by removing bark, ensuring clean surfaces for glue adhesion. The low wood loss (≤5%) reduces material costs for manufacturers, while clean wood surfaces improve veneer quality by minimizing defects caused by bark residue.
Paper and Pulp Industry
Provides bark-free wood chips for pulp production, improving paper quality by reducing contamination. Debarked poplar chips produce pulp with 5–8% higher brightness and 10% better strength compared to chips with residual bark.
Bioenergy Sector
Separated bark can be pelletized for biomass fuel (calorific value 18–20 MJ/kg), while the debarked wood is used for energy-dense wood pellets (20–22 MJ/kg). This dual-output capability enhances resource utilization and revenue streams.
Woodchip Export
High-quality, bark-free poplar chips meet international standards (e.g., EU Timber Regulation) for export to markets like China and Europe, where strict phytosanitary regulations prohibit bark to prevent pest transmission. The machine's high peeling efficiency ensures compliance with <1% bark content requirements.
Working Principle
Logs are fed into the debarker and rotated or conveyed through the debarking zone. The debarking tools remove the bark while preserving the wood surface. Cleaned logs are then transferred to the next processing stage, such as peeling or cutting.
