Production Flow
Process
Material Dosing section
The building gypsum is transported to the building gypsum silo for
later use. Modified starch, coagulant and other raw materials are
sent to their respective hopper for use. After the raw materials
such as building gypsum, modified starch and coagulant were
measured separately, they were mixed in screw mixer and sent
continuously to vertical mixer The foaming agent is quantitatively
added to the tank.When used, the foaming agent and water are sent
to the foaming device respectively, and then the compressed air is
connected to produce stable foam, then sent to the vertical mixer.
When producing the waterproof gypsum board, the waterproof agent is
pumped to the mixer after being Measured.
After the adhesive glue is arranged in the pot, it is fed into the
sizing mouth of the forming station, and the adhesive tape is
applied on both sides of gypsum board top paper The upper and under
cover paper is transported to the paper rack by electric hoist. The
under paper is sent to the forming station through tensioning
device, nicking device and rectifying device. Various raw materials
and water are mixed into gypsum mixed paste with a certain
consistency in vertical mixing machine.The gypsum slurry flows from
the vertical mixer to the forming under paper. The upper paper is
sent to the forming station through the tensioning device,
rectifying device and gluing device, through the shaking table,
under paper folding edge and cover the upper paper. and then
extruded into the board of specified thickness and width. The
formed gypsum board with certain strength after transported by
solidification belt machine.The paper faced gypsum board belt is
smoothly sent to the cutting machine through the conveyor table,
cut off according to the set length (slightly longer than the
finished product), and then sent to the 1# transverse conveyor. The
waste board is sent out of the production line by the waste belt
and the qualified boards are turned upside down and sent to the
dryer by the dispenser for drying.
Drying section
The board is sent to each layer of the 8 layers dryer by the bridge
distributor in sequence according to the program, and the dryer
takes the heat conduction oil of natural gas as the heat source. H
The hot air is provided by burning natural gas inside special
burner. As the board progresses slowly in the dryer, it is heated
continuously with hot air. The free water in board slowly
evaporates, but does not destroy the crystal water. When coming out
the dryer, the board moisture content is ≤1%. Air duct system on
top of dryer.The circulating air ducts are divided into two
sections, each consisting of burner, induced fan, exhaust chimney,
various air ducts, supports and regulating valves.The regulating
valve is provided at the spray nozzle in the air jet section and
between the roller beds.
