Gypsum board production line process description

Preparation:

Modified starch, retarder, pulp, water reducer, and water are quantitatively measured and put into a hydraulic pulper to be mixed into a raw slurry, which is then pumped into the slurry reserve tank for use.

The foaming agent and water are put into the foaming agent preparation tank according to the proportion and stirred uniformly, and the foaming agent storage tank is pumped (with heating device, keeping above 35 DEG C);

The coagulant and gypsum powder raw materials are fed into the silo for backup after being lifted;

Ingredients:

The slurry in the slurry storage tank is pumped into the mixer using a metering pump. The foaming agent enters the mixer after foaming using a dynamic foaming device. The coagulant and gypsum powder are metered into the blender after weighing with a fully automatic measuring belt. Then all the masters The auxiliary materials are mixed into a qualified gypsum slurry on the mixer.

Explanation:

The addition of all main and auxiliary materials is included in the automatic control system, and is automatically adjusted according to the speed of the production line to meet the requirements of large-scale and high-speed.

After the paper has been unwound, the forming and conveying part enters the molding machine through the automatic correcting machine. After the paper is uncoiled, the automatic correcting machine, scoring machine and vibration platform enter the molding machine. The slurry of the mixer falls on the lower plate of the vibration platform and enters the molding machine. Gypsum board of the required specification is extruded on the molding machine, and then initial coagulation is completed on the solidification belt, final condensation is performed on the conveyor roller path, and the desired length (2400mm, 3000mm or other) is cut by the fixed-length cutting machine and passed through 1#. The transverse machine is steered. After the two gypsum boards are turned away from the 1# transverse machine at the same time, the distance between the two plates is then used to reach the requirements after being turned by the distribution roller, and then distributed into the dryer for drying.

The drying section adopts a fuel-type heat-conducting oil furnace as a heat source. After the hot oil is exchanged with the finned heat exchanger, the hot oil is sent to the dryer through a fan to complete the drying task. This dryer is divided into two areas and can be completed very well. Gypsum dry the drying curve to avoid overheating, dripping and other defects. The process is environmentally friendly, energy-saving, high in thermal efficiency, and easy to control process parameters.

After the horizontal section dryer completes the drying task, it is sent to the 2# transverse system through the output machine to complete the fixed-length trimming and automatic edge wrapping of the gypsum board, and then sent to the automatic stacker stacker by the product conveyer and piled up. After the completion of the use of forklift transported to the packaging area inspection packaging, complete the production process.
