Factory direct-300000M3/year aac block/aac block plant-AAC quality assurance  

1. Basic Introduction of AAC Block: aac production line/aac plant

Main raw materials of AAC are siliceous material (sand, fly ash and Silicon tailings) and Calcium materials (lime and cement) mixed with foaming agent (aluminum powder). It is the product of light porous silicate through the following processes: batching, mixing, pouring, hardening, cutting, autoclaving and curing etc. Because of large amount of well-distributed tiny pores after foaming, it is named autoclaved aerated concrete.

2. AAC Classification :   aac block

In general, it can be classified according to the types of raw materials,   manufacture process and functions. Based on the shape of AAC products, it can be divided   into: AAC blocks and AAC panels. It is a revolutionary material offering an unique combination of high durability and strength, low weight, excellent heat insulation, fire resistant, noise absorption, unprecedented build ability and superior ecological green features. In China, AAC is one of the light wall materials which was popularized and applied at the earliest and the most widely.

7. AAC Production line Process:  aac production line/aac plant

8.Main Production Facility of AAC:  aac production line/aac plant

8.1.       Prepared Facilities for Raw materials (1)Crusher: block materials like quicklime, gypsum etc which have to be crushed before using; (2) Grinding Machine: materials have to be grinded before reacting, mainly use ball mill with two types – dry and wet

8.2.       Metering Facilities: wholly automatic system is usually controlled by microcomputer

8.3.       Mixing and pouring Facilities: mixer is the mixing machine and also the slurry pouring machine

8.4.       Cutting Machine: Autoclaved aerated concrete shapes blocks after pouring and foaming. Because of big size, blocks have to be cut into product size.

8.5.       Autoclave: it is the facility for silicate product to do hydration reaction to gain physical mechanical property. The operation is related to workplace safety and energy use.

8.6.       Boiler: it is used to provide autoclave and hardening room with thermal energy

8.7.       Auxiliary Facilities: (1) Model frame, side plate, trolley, these facilities are used to made up pouring mould. (2) Autoclaving cart, ferry cart, hoister, these facilities are necessary to autoclaving and curing system.
