The calcium silicate board equipment includes a series of calcium silicate board production lines. What equipment does the calcium silicate board production line need? The calcium silicate board production lines are also configured differently according to different processing techniques and annual output. Among them, the production line equipment of calcium silicate plate by slurry method includes: pulp treatment system, pulp section, plate stacking and demoulding section, pressure steaming and curing section, grinding and chamfering sanding section.
The production process of calcium silicate board mainly includes the following:
1、Pulp method: The principle is that the slurry is spread on the blanket, dehydrated and laminated; the equipment requirements are simple and the output is low.
2、Copy method: the principle comes from the circular mesh papermaking process; high equipment requirements and high output.
3、Extrusion molding method: semi-wet production, pressure extrusion into the required shape.
The above three methods are mainly based on the copying method and the pulping method. For details, you can consult Jiurui technicians according to the raw materials and output of the calcium silicate board produced. We will design the appropriate production line and equipment configuration for you free of charge according to your situation.

The production process of calcium silicate plate flow slurry method
1、Raw material preparatio
Raw material preparation includes wet grinding and pulping of quartz sand, crushing and digestion of quicklime, grinding and pulping of wood fiber, etc.
2、Pulping process
Pump the wood fiber pulp that is diluted and thinly ground to meet the beating degree requirements into a countercurrent mixer, sequentially add metered slaked lime, cement, quartz powder, etc., and fully mix it through the countercurrent mixer to make a certain concentration of flow slurry and then pump it to The slurry storage tank is used for standby, and then it is evenly ground by a single-disc refiner, stirred in a pre-stirred tank, and input to the flow slurry.
3、Slurry plate
The slurry uniformly flowing out of the headbox, after filtering water on the running industrial blanket and dewatering, forms a thin material layer wound on the forming cylinder, and when the set slab thickness is reached through multi-layer winding, the control system automatically cuts off the slab according to the design size of the slab. The plate making machine adopts a 1600mm diameter forming cylinder, and the slab is cut and trimmed transversely to form 2 standard plates. Standard slabs are stacked by stacker, which adopts the stacking method of one steel mold and one plate.
4、Plate compaction
The formed slab is pressurized by a 7000t press for 30min to dehydrate and compact the slab under a high pressure of 23.5MPa to improve the strength and compactness of the slab.
5、Preconditioning and demoulding
The wet slab is pre-cured in a pre-curing kiln and demoulded after the slab obtains a certain strength. The preconditioning temperature is 50~70 ℃, and the preconditioning time is 4~5h.
6、Autoclaved curing
After the slab is demoulded, it is sent to a autoclave for autoclave for 24 hours, with a vapor pressure of 1.2MPa and a temperature of 190 ℃. During the steaming process, the silicon dioxide, calcium hydroxide and water in the slab undergo chemical reactions to form Tobermullite crystals and xonotlite. The quality of hydration reaction directly affects the strength, expansion rate and moisture resistance of calcium silicate plate.
7、Drying, sanding, edging
The steamed slab is dried on a comb dryer in the tunnel kiln so that the moisture content of the slab reaches the acceptance standard of not more than 10%. The slab can be shipped after sanding, edging and quality inspection.
Advantages of calcium silicate board processed by calcium silicate board production line:
1、Fireproof, waterproof, moisture-proof, sound insulation, heat insulation, corrosion resistance, high strength
2、Anti-seismic, anti-collision, anti-ultraviolet, anti-weatherization, anti-static
3、Easy to clean, durable use, long life
4、Safe, green and environmentally friendly, economical and easy to construct
5、It can be further processed on the foundation board with strong customization.
