Our advanced AAC panel production line is engineered to transform raw materials into precision autoclaved aerated concrete panels with exceptional speed and reliability. Designed as a fully integrated solution, it seamlessly combines the AAC block machine for uniform mixing and slurry control with a complete AAC block production line that accommodates both panel and block outputs on a single platform. This flexibility makes it the ideal foundation for any large-scale AAC plant, where continuous operation can achieve annual capacities from 50,000 to 300,000 cubic meters without compromising product integrity. Every element of the AAC production line is synchronized via a central PLC system that governs batching, mixing, casting, pre-curing, cutting, and autoclaving—drastically reducing manual intervention while increasing throughput. The system incorporates a robust steel reinforcement handling unit that automatically welds, cuts, and places corrosion-protected mesh or cages into the mold, ensuring the panels achieve superior flexural strength for floor and wall applications. Energy recovery from autoclave exhaust and an efficient vacuum lifting system for demolding and stacking further distinguish this line, lowering operational costs by up to 20% compared to conventional setups. Component-level highlights include a high-shear mixer with anti-block paddles, a twin-screw conveying system for lime and cement, and an aluminum powder dosing unit accurate to ±3 grams, all contributing to a consistent pore structure and a final product density as low as 400 kg/m³.
The AAC panel production line raises the benchmark for panel-specific manufacturing with a dedicated pre-curing tunnel that accelerates green strength gain and allows faster mold cycling. This phase is critical for panel quality, as it ensures the green cake is firm enough to withstand the stresses of horizontal high-tensile wire cutting. The cutting frame uses automatic wire tensioning and an optical positioning system to deliver dimensional tolerances of ±1 mm in length and width, with thickness control at ±0.5 mm, even across the largest panel sizes. After cutting, the panels are loaded onto autoclave cars and cured under saturated steam pressures of 1.2 to 1.5 MPa, with precisely controlled temperature ramps reaching 190–210 °C. The autoclaves are fabricated from boiler-grade steel with full-penetration welds and are certified to ASME or EN standards, ensuring safe long-cycle operation. The table below summarizes the core technical specifications of the line, which can be scaled and customized for plot size, output targets, and specific panel dimensions.

Beyond the core machinery, the AAC panel production line includes a comprehensive raw material preparation section: a ball mill for sand grinding (fineness <10% residue on 200-mesh), insulated lime and cement silos with level sensors, and automated weigh hoppers. The casting section leverages a tilt-table pouring system that distributes slurry evenly over the reinforcement, eliminating air pockets. After cutting, panels pass through a grouping and spacing station that configures them for optimal autoclave loading density, reducing curing time per cycle. Finished panels are stacked using vacuum spreader beams and packaged with automated strapping and wrapping systems suitable for open-yard storage. Environmental controls are integrated throughout; dust collection hoods at the batching and mixing stations keep particulate emissions below 5 mg/m³, and a water treatment loop recycles process water and condensate. This end-to-end engineering ensures that the AAC panel production line not only meets but exceeds ASTM C1693, EN 12602, and equivalent standards for reinforced AAC panels, providing builders and specifiers with a product that delivers outstanding thermal insulation, fire resistance up to four hours, and design flexibility for floor, wall, and roof systems.
