Air grader for the Particle board production line/Air sifter machine for Chip board machinery
Air grader/Air Sifter (also known as wind sifter or air separator) is an essential core sorting device in the particle board production line, specially designed for precise classification and impurity removal of dried wood flakes after mechanical screening. It optimizes wood flake grading based on aerodynamic principles, effectively improving the raw material purity and structural uniformity of particle boards, and is a key piece of equipment to stabilize finished board quality and reduce defective rates.
Working Principle
The air sifter operates by utilizing the difference in suspension speed of wood flakes with varying thicknesses, densities and shapes in a stable airflow. After entering the zigzag sorting chamber, mixed wood materials are fully fluidized and stratified by adjustable high-speed airflow. Light, standard qualified fine and medium wood flakes are carried forward by the airflow and sent to the next gluing and forming process. Meanwhile, overweight impurities such as sand, stones, metal debris, as well as oversized, ultra-thick unqualified wood flakes sink and are discharged separately by gravity. This pure airflow physical sorting method realizes accurate light-heavy material separation without damaging the wood flake structure.
Core Functions in Particle Board Production
-
Precise Flake Grading: Effectively separates over-thick flakes and fine powder, retaining standardized flakes for surface and core layer paving, ensuring layered structural rationality of particle boards.
-
Heavy Impurity Removal: Eliminates sand, gravel, metal residues and other hard impurities thoroughly, preventing equipment abrasion, board surface pits and delamination defects.
-
Optimize Board Structure: Uniformly graded wood flakes ensure consistent density, flatness and internal stress of finished particle boards, improving nail-holding power and overall stability.
-
Improve Production Efficiency: Reduce the burden of subsequent processes, lower the defective rate of hot-pressed boards, and improve the overall yield of the production line.
