| Tubular Particle Board Production Process |
| Raw materials - Fast-growing wood (economical and environmentally friendly Poplar, pine, eucalyptus, fir, cryptomeria, rubberwood, etc., grow fast and have low costs - Hard miscellaneous wood (for enhancing strength Birch, oak, elm and other woods have high density and are suitable for high-strength particleboard - Wood processing residues (resource recycling) Sawdust, wood shavings and offcuts (from furniture factories and sawmills). Wood chips, branches and twigs (residues from forestry logging) - Recycled wood (environmentally friendly but requires treatment) Waste furniture, construction formwork, pallets, etc. (Metal, paint and other impurities need to be removed) - Agricultural residues, such as straw: rice husks, wheat stalks, corn stalks, bagasse (special treatment is required to reduce sugar content) |
Drum Chipper The drum crusher (also known as the drum chipper) is a coarse crushing equipment used for raw materials such as wood, straw, and waste boards, and is widely applied in industries like particleboard, fiberboard, and biomass fuel. Its core function is to break large pieces of wood or wood waste into fragments suitable for subsequent processing (wood chips, wood shavings or fiber raw materials). Core features High-efficiency crushing: Suitable for large-diameter wood (up to 50cm), branches, old furniture, etc. Controllable particle size: By adjusting the blade gap or replacing the screen, 5-50mm wood chips can be output. Strong adaptability: It can handle wet materials, dry materials, tree bark and even non-wood raw materials (such as straw). Easy maintenance: The blades can be used in reverse or replaced quickly, reducing downtime. |
| Rotary Drum Dryer Dry the wet wood shavings (with a moisture content of 30% to 50%) to 2% to 4% of the process requirement. Core features High-efficiency drying: The processing capacity of a single device can reach 5 to 30 tons per hour (depending on the specifications). Temperature control: Staged heating (such as high-temperature zone → medium-temperature zone → low-temperature zone) to prevent the coking of wood chips. Strong adaptability: It can dry wood shavings of different tree species (such as pine and poplar) and particle sizes. Energy-saving design: Recovery of waste heat from exhaust gas to reduce energy consumption |
Vibrating Screen Particle size grading, impurity removal and raw material particle size control are carried out to ensure the stability of subsequent sizing, laying and hot pressing processes. Core functions and advantages Precise grading: The wood shavings are classified into surface fine material (0.2-1mm) and core coarse material (1-5mm) according to the process requirements. Removal of impurities: Screen out foreign substances such as metal fragments and sand and gravel (requiring the use of a magnetic separator). Improve uniformity: Avoid coarse wood shavings from mixing into the surface layer, which may affect the surface quality of the board. Energy-saving and highly efficient: The processing capacity can reach 5 to 20 tons per hour, with low power consumption |
| Glue Blending system It is used to evenly mix wood chips with adhesives (such as urea-formaldehyde resin, MDI glue, etc.) to ensure that the surface of each wood chip is fully covered with the adhesive solution, thereby forming a strong bonded structure during the hot pressing process Core functions and advantages Uniform application of glue: The coverage rate of the glue solution should be over 95% to avoid insufficient or excessive glue in some areas. High-efficiency mixing: The processing capacity can reach 5 to 30 tons per hour (depending on the model). Flexible adaptability: It can handle different tree species (pine, poplar, etc.) and adhesives (UF, PF, MDI). Energy-saving design: Low-speed stirring reduces the crushing of wood chips and energy consumption. |
Slab forming line The wood shavings mixed with glue are evenly laid into continuous board blanks (Mat), and the laying quality directly affects the density distribution, strength and surface flatness of the board. Core functions and advantages Uniform paving: The density deviation of the slab should be controlled within ±5% to avoid deformation after hot pressing. Hierarchical control: Achieve a "fine - coarse - fine" structure to optimize the strength and surface quality of the sheet. High-efficiency production: The laying speed can reach 10 to 50 meters per minute (depending on the thickness of the board and production capacity requirements). Flexible adaptation: The laying parameters can be adjusted to produce particleboard of different specifications (thickness 8-40mm) and densities (550-750kg/m³). |
| Continuous Multi-rollers Pre-press It is used for the initial compaction of loosely laid slabs (Mat) to endow them with certain strength and density, expel air, facilitating transportation and enhancing the efficiency of hot pressing Core functions and advantages Enhance the strength of the slab: Reduce damage or deformation during transportation. Optimize hot pressing efficiency: The density of the slab is more uniform after pre-pressing, and the hot pressing time is shortened. Energy conservation and consumption reduction: Reduce the energy consumption of the hot press (as the slab has been initially compacted). Prevent "plate burst" : Pre-press to expel some air and reduce the risk of bubbling during hot pressing |
Synchronous Cross-cutting saw It is used to precisely cut the continuously pre-pressed or hot-pressed plates horizontally to the set length to ensure that the finished product size meets the standard (such as 1220×2440mm). Its cutting accuracy directly affects the utilization rate of the sheet and the quality of subsequent processing |
| Multi-opening Hot press It is used to cure the adhesive on the pre-pressed slabs under high temperature and high pressure to form high-strength finished slabs Core functions and advantages High-efficiency production: Multi-layer design (such as 8-30 layers) can simultaneously press multiple sheets of board, increasing production capacity by 3 to 5 times. Precise temperature control: Each layer is independently temperature-controlled to prevent local overheating or insufficient bonding. Uniform density: High pressure ensures that the density difference between the core layer and the surface layer of the board is less than 10%. Flexible adaptability: It can produce particleboards of different thicknesses (8 to 40mm) and densities (550 to 750kg/m³) |
Continuous Flat Press Suitable for Large-scale production capacity in a continuous and uninterrupted working way, compare the tradiational Multi-layers hot press, it is high efficiency, high precision and low energy consumption. Core functions and advantages Ultra-high efficiency: 24-hour continuous production, with a speed of up to 60m/min (18mm board production capacity is approximately 2000m³ per day). Accurate thickness: Online thickness measurement feedback, thickness deviation < ±0.2mm. Energy conservation and consumption reduction: It saves 20% to 30% energy compared with multi-layer presses (with less heat loss). Excellent surface quality: The steel strip pressing makes the surface flatter, eliminating the need for sanding or only requiring light sanding. Flexible production: Quick switching between thickness (2-40mm) and density (500-800kg/m³) |
| Automatic Edge Cutting Machine The edges of the hot-pressed plates are trimmed to ensure that the finished products have precise dimensions and neat corners Remove the irregular burrs from the hot-pressed sheet Cut the sheet to the standard size (such as 1220×2440mm) Eliminate the bonding defects and loose layers at the edges of the board |
Sanding Machine Line Grind and polish the surface of the particleboard to improve its flatness and smoothness Main functions Remove the unevenness on the surface of the particle board Eliminate the thickness differences of the plates Improve the surface finish Prepare for subsequent processes such as veneering and painting |
