AAC Block Manufacturing Plant also named as Aac Block Making Plant, AAC block production line, it`s used to produce the AAC block from two main materials, one is sand and the other is fly ash, so there are two solutions for AAC block production, namely fly ash block production process and sand block production process, the main difference between the two processes is that it needs another Ball Mill to grind the sand into fine powder, for slurry making purpose with good characteristics. However fly ash is from industrial waste which is almost as fine powder, so it`s not necessary to grind, besides the main materials, it still needs the other additives, such as gypsum, lime, aluminum powder, cement. AAC block features light weight, fireproof, sound insulation, Permeability, which makes it popular in the building industry.
