fiber cement board making machine usage and slurry preparation
Gypsum ceiling board is laminated PVC film in front side and aluminum film in back side of paper faced gypsum board. The features are waterproof, moisture proof, flame resistant, thermal insulation,radiation proof, anti-sagging, non-deformed, etc.
1.Put cement, quartz powder, pulp, and other raw materials with water (controlled by Φ4000 backwater tank) in the pump beater. All material will be mix up in here continuously until reach the standard.
2.Transfer slurry to bucket slurry storing pool, and keep the mixing process to keep the consistency. After that, slurry will be pour on the running carpet, dehydrate through the vacuum chamber, compact and roll on the forming roller. The layer of the slurry will keep adding the thickness and dehydration. Thus, basic format of the board formed, called slab.
3.The left over liquid after the dehydration process will be collected and pump back to the mixed water tank for reuse. After the precipitation, sediment will be sent back to the pump beater with raw material for reuse. Mixing water will also sent back for adjust the consistency of the slurry. Clear water will use for washing the running carpet.
4.Detach slab from the forming roller, and longitudinal shearing machine will be used in here to cut both side of the slab.
