MDF production process The first step is the preparation, equipment, mainly cutting machine, belt conveyor, screening machine, bucket elevator, storage silo and so on. MDF production of raw materials mainly wood fiber raw materials, which include small-diameter wood, branches, firelogs, processing residues, the ideal raw materials for the preparation of coniferous 60%~70%, hardwood 30%~40%, bark content not exceeding 5%.
2. Preparation of fiber
The preparation of fiber is mainly fiber separation, is the core process of MDF production technology. The fiber separation equipment has a chip silo (or preheating silo), a small hopper, a hot mill, a paraffin melting and exerting device, and a sizing device.
