gypsum board machine Forming section
The upper and lower paper is conveyed to the cardboard station by electric hoist. The lower paper goes through cardboard tension device, indentation device and swing correction device to the forming station, while the plaster slurry of certain consistency, which is formed in the vertical mixer from various kinds of solid powered materials and liquid materials, flow out onto the lower paper at forming station. Meanwhile, the upper paper goes through tension device, swing correction device, and edge adhesive and then to the forming station. The upper and lower paper together packs the plaster slurry to get plasterboard with specified thickness. After going through the setting belt conveyor, the formed plasterboard has certain strength.
The wet plasterboard with certain strength are conveyed to the cutting machine stably via roller conveyor and cut as per preset length (little longer than the finished product), then conveyed to 1# transverse conveyor via accelerating roller. In which, the rejected board is conveyed out of the production line via reject board belt conveyor and the qualified board is turned over and queuing to enter the dryer. Dosing system gypsum board machine
1. dry raw materials dosing, example gypsum powder, modified starch, other additives
2. wet raw materails dosing, example water, foaming agent, other additives
Dry material dosing gypsum board machine
The building plaster is conveyed to the weighing belt via bucket elevator, screw conveyor and rigid vane feeder and then conveyed into the screw conveyor for mixer. This system has material internal circulating function for over flow of material sent to weighing belt to make conveying process quite stable.
Modified starch and other dry additives are conveyed to the screw conveyor for mixer after metering.
Glass fiber used for producing water-resistant and fire-resistant plasterboard is added to the screw conveyor for mixer after cutting.
The above mentioned dry materials pre-mixed in a special powder mixer for making additives homogeneously distribution and then conveyed into the slurry mixer.
Wet material dosing
This production line has special foaming device. After metering, the foaming agent and water is pumped to the foam generator respectively via screw pump, the compressed air is also conducted into the foam generator after metering. The foam generator produces stable foam and sends it to the vertical mixer directly.
Water is pumped into the slurry mixer directly.
The adhesive glue prepared in the tank is applied on both side of the upper paper of the plasterboard with the level difference.
