Sand AAC Production Line

Sand AAC production line is a kind of autoclaved aerated concrete (AAC) block making process that uses sand as the main raw material. Sand AAC blocks are lightweight, fire-resistant, sound-insulating and eco-friendly building materials that can be used for various construction purposes.

The sand AAC production line consists of several steps, such as:

– Sand preparation: The sand is washed, dried and sieved to remove impurities and achieve the required fineness.
– Lime preparation: The lime is crushed, milled and hydrated to produce slaked lime, which is then mixed with sand and water to form a slurry.
– Cement preparation: The cement is ground and stored in silos, ready to be added to the slurry as a binder.
– Aluminum powder preparation: The aluminum powder is mixed with water to form a paste, which acts as a foaming agent in the slurry.
– Slurry mixing and pouring: The sand-lime slurry, cement and aluminum paste are mixed together in a mixer to form a homogeneous mixture, which is then poured into molds and leveled.
– Pre-curing and cutting: The molds are transferred to a pre-curing chamber, where they are kept at a certain temperature and humidity for several hours. The slurry solidifies and forms green cakes, which are then cut into blocks of desired sizes and shapes by a cutting machine.
– Autoclaving and packing: The cut blocks are loaded onto autoclaves, where they are subjected to high pressure and temperature for several hours. The blocks undergo a chemical reaction that makes them strong and durable. The blocks are then unloaded from the autoclaves and packed for transportation or storage.

Sand AAC production line has many advantages over traditional concrete block making methods, such as:

– Low energy consumption: Sand AAC blocks require less energy for production and transportation than conventional concrete blocks, as they are lighter and have better thermal insulation properties.
– High quality: Sand AAC blocks have uniform dimensions, smooth surfaces and accurate angles, which make them easy to install and reduce wastage.
– Environmental protection: Sand AAC blocks use natural materials that are abundant and renewable, such as sand and lime. They also produce less dust, noise and waste during production and use.
– Wide application: Sand AAC blocks can be used for various building projects, such as walls, floors, roofs, partitions, etc. They can also be customized to meet different design requirements, such as colors, textures, patterns, etc.

Sand AAC production line is a cost-effective and eco-friendly solution for modern construction industry. It can help improve the quality and efficiency of building projects, while reducing the environmental impact and carbon footprint.
