Description of China Brick Machine/AAC plant,AAC block production lineWe supply the entire solution of the AAC plant,Capacity from 50,000m3-350,000m3 PER year.

AAC Block Production LineAAC is made from silicon material (silica sand, or recycled fly ash and silica gangue) and calcium material (lime, cement), mixing with foaming additive (aluminum powder), batching with water, the reaction between aluminum and concrete causes microscopic hydrogen bubbles to form, expanding the concrete to about five times its original volume. It is made into the multi-cells silicate products by the processes of resting, tilting, cutting and autoclaving.

Fly Ash/Sand AAC (Autoclaved Aerated Concrete) Block Plant is actually hydrated calcium silicate. The calcium is obtained from quick lime, hydrated lime and cement. The gypsum is used as a catalyst and for optimizing the properties of AAC. The silica is obtained from silica sand, fly ash (PFA), crushed silica rock and/or stone. It is possible to obtain silica as a by-product from other processes, e.g. foundry sand or burgee from glass grinding, provided the levels of alkalis or other impurities, are not too high.AAC Plant, AAC Cutter, AAC Cutting MachineAAC Procedure: 1.

Process chart Sand AAC Block PlantTo manufacture AAC, cement is mixed with lime, silica sand, or recycled fly ash, water, and aluminum powder or paste. The slurry is poured into moulds where a chemical reaction occurs, the reaction between aluminum and concrete causes microscopic hydrogen bubbles to form, expanding the concrete to about five times its original volume. After evaporation of the hydrogen in the mold for 45mintues, the high closed cellulated AAC unit is cut to size and formed by steam-curing in a pressurized chamber (an autoclave) for 10 to 12 hours. The result is a non-organic, non-toxic, airtight material that can be used for wall, floor, and roof panels, blocks.

Project casesWith abundant air cells and micro apertures inside the aerated brick, it has good performance of heat insulation and preservation. In addition, the most prominent advantage is its plasticity. Due to the lightness and the lower hardness, AAC units are available in numerous shapes and sizes according to the real construction usages and customer's requirements.
