What is the process of the gypsum board production line?
Trimming, stacking section
?????? The paper gypsum paper of the drying machine is conveyed by the roller conveyor, the type 2 horizontal conveyor, the machine is sent into the trimming machine and cut to the required size. The finished plate is fed into the stack by the finished roller conveyor Machine stacking, stacking after the forklift sent to the finished product storage.
Drying section
?????? The paper gypsum board is fed into the layers of the 12-layer dryer by the bridge dispenser. The dryer is divided into two zones. The hot steam is used as the heat source. The hot gypsum board is slowly advancing in the dryer, The flow of hot air constantly heat exchange, the plate absorbs heat, the temperature rises, the plate free water slowly evaporates, but does not destroy the dihydrate gypsum crystal water. When the paper gypsum board out of the dryer, the water content should be ≤ 1%. The paper gypsum board is dried by a dryer, cooled by the cooling section of the dryer, and discharged from the dryer in an orderly manner.
Forming section
?????? Formed paper by the paper machine, tensioning device, marking device, correction device sent to the forming station, gypsum slurry from the vertical mixer to the formation of paper on the next. Forming the paper machine by the paper machine, tensioning device, correction device and glue, sent to the molding station. Molding machine for the plate, the thickness can be adjusted. Molding machine on the paper, the next paper, gypsum slurry squeezed into the provisions of the thickness of the plate, a good gypsum board with a solidification belt conveyor belt conveyor conveyor belt sent to the cutting machine at the set length cut off, and then by the acceleration roller Road into the type 1 horizontal conveyor, by pushing the roller bed into the dryer.
Ingredients section
?????? The material in the silo is conveyed by horizontal and vertical conveying equipment and sent to the belt scale through a rigid impeller feeder. Excess material, then through the back to the conveyor, hoists and other transportation equipment back to the silo.
?????? Building gypsum, modified starch, coagulant, glass fiber (the production of water-resistant paper gypsum board, refractory gypsum board when used) and other raw materials were measured, into the spiral mixer after mixing into the vertical mixer.
?????? The foaming agent is added to the tank. When used, the blowing agent and moisture are pumped from the metering pump to the foaming device and pass through the compressed air to produce a stable foam and feed it into the vertical mixer.
?????? Adhesive glue in the tank with a good mix into the forming station on both sides of the spray mouth, the tape sprayed on the paper gypsum board on both sides of the paper. The upper and lower face sheets are transported by electric hoist to the paper holder.
