50,000M3 AAC Block Plant       Quality from A to Z: For this highly sophisticated manufacturing process, Sievo 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 fnished products

    Process: 1. First,dose and match measured raw materials 2. After distributing,feed raw material into pouring mixer to make slurry 3. Through thoroughly mixing,the slurry is poured to mould 4. After pre-curing under a certain temperture and time,the block would reach a  certain hardness prepare for cutting 5. Tilting hoister would turn over 90 degree of mould 6. Then open the mould and separate it from block,and take the block woth side plate ti cutting cart 7. The blocks then be cut through the cutter firstly of two vertical sides of block 8. Secondly the horizontal cutting 9.  Finally the vertical cutting 10. After cutting,the block is hanged to trolly with side plate by semi-finished product hoister 11. Organizing the cut blocks and put them into autoclave 12. Hardending the blocks under certain temperture and pressure 13. Take finished products out of autoclave 14. The finished product hoister take the finished product to stock shield 15. Packed for loading 16. The side plate return back by side plate roller 17. Side plate would be organized with open mould 18. Clean the mould and preparing for next pouring 19. Steel bars processing line for slab production   Layout Drawing of Production Line of Autoclaved Aerated Concrete    AAC blocks and panels    Vario-Block und Vario-Panel The Vario-Block allows  Sievo customers a fexible and economic plant concept for aerated concrete block manufacturing. The green cake is in the start phase of the manufacture. It is automatically demoulded and set in an upright position where it is calibrated, profled and then cut in length and width. Also the grip pocket is formed while in the “green condition”. By modifying installed components, the Vario Block process can be expanded to the Vario Panel system, which allows the production of reinforced elements up to 6 metres in length.   Aggregates Storing, Mixing, Pouring    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 defned 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. Aggregate storing and measurement Sand storing Sand preparation and transport Milling devices Storage of binding agent and additives Mixing and dispensing Aggregate dosing and mixing devices Moulds, hardening floors Process / installation controls          Cutting and conveying  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, profled, and cut both horizontally and vertically.

The steam pressure chambers work fully automatically and are highly energy efficient due to an optimised process in control technology. The curing process follows exact defined
procedural steps. The curing time depends on the density and the grade of open pores of the cake. Finally, before leaving the plant, the finished products are packaged in a way that they are protected from dirt and humidity. Depending on the installation concept the packaging process can be either fully or semi automatic.
