Equipment Configuration of Sawdust Production Line
Equipment Configuration & Technical Highlights
1. Log Preprocessing System
Hydraulic Log Feeder:Automated feeding mechanism with anti-jamming design, handling logs up to 30cm in diameter.
Drum Chipper:High-speed rotating blades convert logs into 1-3cm wood chips, with adjustable cutting depth for uniform chipping.
Magnetic Separator:Removes metal impurities to protect downstream equipment, ensuring processing safety.
2. Crushing & Screening System
Heavy-Duty Hammer Crusher:Equipped with wear-resistant alloy hammers, crushing wood chips into 2-5mm sawdust particles, suitable for both softwood and hardwood.
Multi-Layer Vibrating Screen:3-tier screening structure separates sawdust into different particle sizes (≤1mm, 1-3mm, 3-5mm) to meet diverse application needs.
Cyclone Dust Collector:Integrates dust removal system with 99% efficiency, complying with EPA standards for air quality.
3. Drying & Conveying System
Rotary Drum Dryer:Utilizes hot air circulation to reduce moisture content from 40% to 8-12%, with heat recovery system cutting energy consumption by 30%.
Belt Conveyor with Sealed Enclosure:Stainless steel conveyor belts ensure dust-free material transfer between processes, enhancing operational safety.
4. Intelligent Control System
PLC Centralized Control Panel:Monitors real-time production data (feed rate, particle size, moisture) and adjusts parameters automatically for optimal efficiency.
Remote Monitoring Module:Enables remote diagnostics and maintenance via cloud connectivity, minimizing downtime.
Production Process of Sawdust Production Line
Production process
1. Log Feeding & Chipping
Logs are loaded into the hydraulic feeder, which transports them to the drum chipper for primary chipping. The chipper's precision blades ensure uniform wood chips, ready for subsequent crushing.
2. Fine Crushing
Wood chips enter the hammer crusher, where high-speed rotation and impact forces reduce them to sawdust. The crusher's adjustable screen allows customization of particle fineness.
3. Screening & Classification
Crushed material passes through the vibrating screen, separating undersized (≤1mm), standard (1-3mm), and oversized (3-5mm) particles. Oversized fractions are recycled for re-crushing.
4. Moisture Control
Depending on end-use, sawdust may enter the rotary dryer to achieve target moisture levels (8-12% for biomass fuel, 4-6% for wood boards).
5. Packaging & Storage
Finished sawdust is conveyed to automatic bagging machines (5-50kg specifications) or bulk storage silos. Anti-humidity packaging ensures product stability during transport.
Raw Material Type of Sawdust Production Line
Raw material type
Softwood
Pine, spruce, fir – ideal for low-ash biomass fuel and wood pulp.
Hardwood
Oak, beech, maple – suitable for high-density wood boards and premium charcoal.
Mixed Wood
Industrial waste from furniture production, construction debris, and tree trimmings – cost-effective for bulk applications.
Finished Product Specifications of Sawdust Production Line
Finished Product Specifications
| Parameter | Standard Range | Application Notes |
|---|---|---|
| Particle Size | 0.5-5mm | Adjustable via screening for different uses (e.g., 0.5-1mm for wood powder, 3-5mm for biomass pellets). |
| Moisture Content | 8-12% | Ensures combustion efficiency in biomass applications; lower levels (4-6%) for board manufacturing. |
| Bulk Density | 200-400 kg/m³ | Varies by wood type; hardwood sawdust offers higher density for compressed products. |
| Impurity Content | ≤0.5% | Metal, bark, and foreign matter strictly controlled for industrial quality standards. |
