Fully Automatic 300~1500 Cbm Per Day MDF/HDF Continuous Press Production Line

Description

Chip prepare section
Drum chipper is our conventional product widely used in the industrial production of paper, MDF and PB, etc. Raw materials are
primarily small diameter logs, logging residues such as branches and twigs as well as wood-processing leftovers like planks,slabs, cores and veneer wastes, etc.. Our company can also supply a complete set of equipment for chip preparation section.The chipper mainly consists of machine base, knife rotor, upper and lower feeding rollers, hydraulic system and electrical controlsystem.
Fiber prepare section
Chips are transported to upper bin of refiner,
and positively fed to digester by screw feeder for steaming. Steamed chips will be isintegrated to fiber under the force of heat
and mechanism. Mix drying medium and wet fiber which is in the state of suspension with the help of high pressure air flow, and thus exhaust moisture in fiber via drying medium to get dry fiber. Dry fiber falls on belt conveyor through cyclone discharge valve, and then be transported to dry fiber bin for storage.
Glue making and applying section
Process of glue applying before drying is adopted. Feed molten paraffin and water-proof additive to refiner. Paraffin is mixed with fiber uniformly under the force of refiner plates. Glue is transported to the blow line of fiber discharge valve. This section can be controlled by PLC or computer.

The 300~1500m³/day MDF/HDF production line uses raw material through chips preparation, fiber manufacturing, glue dosing system, forming and hot pressing, cooling &trimming and sanding section to make MDF/HDF board. The final size can be 4 x 8, 6 x 8, 6 x 9, 4 x 12, 6 x 12, 6 x 18. The MDF/HDF board has homogeneous structure, smooth surface, good machining specification and manufacture performance. It is the ideal substitute of nature wood.
