Advantage of Gypsum Plasterboard Production Line

After shaping, the boards are cut into required length by PLC servo controlled knife automatically. This knife can easily cut to be different lengths as preset in the PLC system.   After cutting, the wet gypsum boards are detected and quick conveyed by speedup conveyor to 1# cross belt conveyor area, the waste boards are going out of the running line by its belt conveyor, and quality boards are lifting and turning over by inverter/turning machine, to turn the backside face to machine and face side upward, then grouped into two rows and then sent to tippler/distributor machine, which will distribute boards into different layers of dryer entry end automatically. This system is full automatically controlled by PLC. After dryer feeding, faceside of board is up to effectively prevent front side from potential damage during drying; to make full use of space and heat in the dryer more effectively.
