Automatic AAC Brick Machine Plant/light weight brick machine Autoclaved Aerated Concrete Line(AAC), for this highly sophisticated manufacturing process, Shandong Dongyue Building Machine Co., Ltd has all the components and technology available. The manufacture of aerated concrete places great demands on the dosing of raw materials, the supervision of the fermentation process and the control of the following production steps. Many years of experience and the deployment of the latest automatic control algorithms in our control components guarantee the quality of the finished products. The basis for continuous high quality Aerated concrete is produced from quartz sand, lime, cement, gypsum (anhydrous), and water. The process starts with quartz sand being milled in a wet ball mill into a fine sand slurry which is then stored in slurry silos with an integrated stirrer. It is important to keep the defined density, which is controlled either manually or automatically. Sand slurry, recycled slurry, lime, cement, gypsum, aluminum and water are added to the mixer according to the desired product recipe. Immediately after the mixing the pre-positioned moulds are filled and subsequently transported to the fermentation area. Here the mixture starts reacting by producing fine pores, allowing the mass to harden into an aerated concrete cake. Consistent precision The fermentation process produces hydrogen, resulting in the creation of billions of tiny pores in the concrete cake. At the end of the process the cake is left with an enormous number of air cells. Simultaneously the aerated concrete cake starts to harden. As soon as the material has enough resistance to be cut, the aerated concrete cakes are demoulded and placed onto the cutting line. Here they are frst calibrated, profiled, and cut both horizontally and vertically.
