Technique Principle
Also known as an Excelsior Cutting Machine or Wood Silk Mill, the Guoyu Wood Wool Machine is purpose-built to transform fresh logs into premium, uniform wood strands. Unlike standard crushers that produce irregular chips, our equipment is specifically designed to create clean, high-quality excelsior with intact wood fibers, making it the perfect raw material for high-end commercial use.
To accommodate different production scales, we offer two versatile models: the standard 500-1 and the high-yield 500-2. Whether you are a startup requiring 50-100 KG/h or a larger facility needing 100-150 KG/h with double-log processing capabilities, we have the right configuration for your business. Powered by robust motors (ranging from 7.5KW up to 15KW main power), our machines guarantee stable, continuous operation even during heavy-duty production cycles.
The superior wood silk produced by our machines opens up highly profitable markets for your business. It is widely demanded across multiple industries—from eco-friendly packing box stuffing and hygienic animal bedding to natural firelighters. Furthermore, it serves as the essential foundation for manufacturing acoustic sound insulation boards and fiberboards. With Guoyu machinery, you are not just buying a machine; you are investing in a versatile production line.
Ideal Wood Wool Solutions for Firelighter Production
Tap into the rapidly growing eco-friendly energy market by producing the perfect base material for natural firelighters. High-quality fire starters require wood wool with specific density and high surface area for optimal ignition. Our machines provide the ultra-thin precision needed to create loose, flammable strands that hold wax effectively. Whether you are producing fireplace starters or BBQ lighters, our technology ensures your raw material meets the highest commercial standards for burn time and reliability.
For Natural Firelighter Rolls
Produce long, continuous, and resilient strands that are easy to mechanical-roll or hand-weave. The Guoyu Wood Wool Machine maintains the integrity of the wood fiber, ensuring the final “nest” structure is sturdy enough for industrial wax dipping without falling apart, providing a premium look for retail packaging.
For Rapid-Ignition Grades
Engineered for maximum surface area coverage. By adjusting our machine to its finest settings (0.1mm – 0.3mm thickness), you can produce feather-light wood silk that catches fire instantly. This “flash-point” quality is essential for high-end biomass starters used in wood stoves and outdoor camping.
For High-Volume Biomass Starters
Scale your production with a consistent output of up to 150 KG/Hour. Our dual-log feeding system (Model 500-2) allows you to process low-cost softwoods like Pine and Poplar into high-value firelighter feedstock. Reduce your manufacturing costs while maintaining a 100% dust-free and eco-friendly product that eco-conscious consumers demand.
Why Choose SinoShred for Firelighter Wood Wool Production?
✅ Adjustable Micro-Thickness (0.1–1.0mm): Customize the excelsior size for different firelighter grades. Produce ultra-thin silk for rapid, instant ignition or thicker strands for longer-lasting burn times.
✅ Superior Wax Absorption Texture: Our precision mechanical shaving (not rough crushing) creates a high-surface-area texture that absorbs and holds paraffin wax perfectly, ensuring a high-quality final product.
✅ Clean & Resilient Fiber Strands: Unlike waste wood chips, our machine produces long, continuous strands that are easy to roll into “nests” without breaking, giving your firelighters a premium, professional look.

Working Principle
Log Loading & Securing
Standard round logs (300-500mm in length) are placed into the machine’s heavy-duty feeding carriage. The automated mechanical system securely clamps the wood in place and provides constant downward pressure. This ensures the log remains completely stable during the high-speed shaving process. (Note: Model 500-2 allows two logs to be loaded simultaneously).
Dual-Blade Precision Shaving
This is the core of the process. As the log moves continuously across the cutting mechanism, it encounters two types of blades working in sequence. First, the Silk Knife deeply scores the surface of the wood to dictate the exact width of the strands (1-10mm). Immediately after, the Flat Knife cleanly slices the scored layer off to determine the thickness (0.1-1mm).
Continuous Excelsior Output
Through this continuous, reciprocating physical planing (not rough crushing), the solid wood is rapidly transformed into long, uniform strands. Because the cutting action respects the natural grain of the wood, the resulting wood wool retains its full fiber strength and elasticity, dropping directly into the collection area ready for immediate use.

Core Advantages
Cutting System: Precision Shaving Configuration
At the core of the equipment is a highly configurable mechanical shaving unit. It utilizes a synchronized combination of specialized Silk Knives (for width scoring) and Flat Knives (for thickness slicing). Operators can precisely dial in the output dimensions, achieving an adjustable width from 1mm to 10mm and a thickness from 0.1mm to 1mm. This physical cutting approach ensures the natural wood fibers remain completely intact and dust-free.
Feeding Carriage: High-Capacity Log Intake
Engineered to accommodate standard fresh timber, the heavy-duty loading carriage supports log lengths ranging from 300mm to 500mm. To maximize daily throughput, the advanced 500-2 model features a widened feeding track specifically designed for simultaneous double-log processing (Max diameter 160mm × 2). This structural optimization effectively doubles the material intake per cycle, boosting the capacity up to 150 KG/Hour.
Drive & Transmission: Independent Motor Architecture
To maintain constant torque during intensive industrial processing, the machine employs a segregated power setup. A powerful primary motor (up to 15KW) drives the heavy cutting action, while dual auxiliary motors (0.75KW × 2) manage the automated carriage movement. The entire transmission is stabilized by industrial-grade components, including FL 204 bearings, one-way bearings, and high-tension V-Belts, ensuring jam-free operation under heavy loads.
Maintenance Toolkit: In-House Blade Sharpening
To minimize downtime and slash operational costs, we provide a dedicated Wood Wool Blade Sharpener perfectly paired with the main machine. Powered by a highly efficient 0.37KW motor, this auxiliary equipment supports a maximum grinding length of 800mm and allows exact grinding angle adjustments (28°, 35°, and 90°). This allows operators to maintain razor-sharp blades on-site, eliminating reliance on expensive third-party sharpening services.
