AAC panel production line
For modern construction projects demanding lightweight, high-strength, and thermally insulated wall panels, a fully integrated AAC panel production line delivers unmatched efficiency. This system builds upon proven AAC block machine core technologies, scaling up to comprehensive AAC block production line levels while incorporating specialized panel forming and reinforcement placement stations. Whether you are upgrading an existing facility or establishing a new AAC plant, the precision engineering behind every component—from raw material dosing to autoclave curing—ensures consistent output of panels with precise dimensions. By integrating advanced cutting machinery and automated handling, the complete AAC production line minimizes waste, reduces labor dependence, and achieves annual capacities from 50,000 to 300,000 cubic meters, adapting seamlessly to market demands for sustainable prefabricated building elements.
The AAC Panel Production Line is engineered to produce reinforced autoclaved aerated concrete panels that meet stringent international building codes. The line typically starts with wet slurry preparation using carefully proportioned silica sand, cement, lime, and aluminum powder, followed by precise reinforcement cage placement within the mold. After initial curing and tilting, the semi-plastic cake is cut horizontally and vertically by ultra-high-precision wire cutters that guarantee edge straightness and dimensional tolerance within ±1 mm. The green panels are then transferred to autoclaves, where saturated steam at 12 bar and 190°C triggers the hydrothermal reaction that gives AAC its characteristic cellular structure and mechanical strength. Below are typical technical specifications and key benefits.
- Raw Materials: Silica sand (or fly ash), Portland cement, quicklime, gypsum, aluminum powder paste, and corrosion-protected steel reinforcement mesh.
- Panel Sizes: Length up to 6,000 mm, width 600 mm, thickness from 50 mm to 300 mm (customizable).
- Dry Density: 500–650 kg/m³, ensuring lightweight handling and reduced structural load.
- Compressive Strength: ≥ 4.0 MPa (cube), meeting load-bearing wall requirements.
- Fire Resistance: 4-hour rating for 100 mm thick panels, non-combustible Class A1.
- Thermal Conductivity: 0.11–0.14 W/(m·K), significantly lowering HVAC energy consumption.
- Production Capacity: Ranges from 50 m³/day for small plants to over 1,000 m³/day for large-scale operations.
- Automation Level: Fully automatic mixing, casting, cutting, and autoclave loading/unloading with PLC control.
