AAC blocks manufacturing process

As the name suggested, AAC block manufacturing plant is designed for aac block manufacturing, AAC block plant mainly uses fly ash (slag or sand) as the raw material, lime and cement as the binding materials, and aluminum powder as the foaming agent. The process includes crushing, measuring, mixing, pouring, pre-curing, cutting, and autoclaving to produce autoclaved aerated concrete block.

Here is a simple guideline of AAC block manufacturing process, to be clear, we just list some main sections of AAC manufacturing plant, if you want more equipment specifications or other details please contact us or have a visit!

STEP1: Raw Material Preparation

The first step is to prepare the raw materials. The key raw materials used in the production process are sand, cement, lime, gypsum, and aluminum powder. These materials are processed by jaw crusher and ball mill, and finely ground material is sent to the powder distribution bin by screw conveyor and bucket elevator, and are transported to the silo through belt conveyors.

STEP2: Batching & Mixing

Secondly, the automatic batching system measures all kinds of raw materials prepared and stored for use, adjusts the temperature and concentration, measures and prepares a small amount of mixed materials, and then feeds them into the mixing equipment at one time according to the technological requirements. Once the raw materials are prepared, they are mixed together in a slurry mixer. The mixer consists of a rotating drum that mixes the materials with water to create a thick slurry. Then, finished slurry is then poured into puring mixer.

STEP3: puring & pre-curing

In this step, the slurry is poured into puring mixer. The puring mixer contains a mold of the desired size and shape of the AAC block. The slurry is poured into the mold, and the bubble remove machine vibrates to remove any air bubbles and ensure that the slurry is evenly distributed. After puring, automatically enter the curing room which can control humidity and temperature to accelerate the hardening of embryo body.

STEP4: Cutting

After the pre-curing, lift the mold frame and the blank body together to the cutting table where the bottom plate of autoclave is placed in advance with the tliting hoister. The cutting machine makes transverse cutting, longitudinal cutting and milling of the embryo, and the cut embryo together with the bottom plate of the autoclave is hoisted to the ferry cart by crane. There are four supports between the two layers, and a number of ferry carts are arranged into a group.

STEP5: autoclaving

The next step in the production process is autoclaving. Autoclave curing is the high-pressure steam curing of aerated concrete embryo. For aerated concrete, only after a certain temperature and sufficient time curing, the embryo can complete the necessary physical and chemical changes, so as to generate strength and meet the needs of building construction. The cutted blocks are placed in an autoclave, which is a large pressure vessel. The autoclave is filled with steam and the blocks are exposed to high temperatures and pressures for a few hours. This process gives the blocks their unique cellular structure and strength. Autoclave is the core equipment of AAC block plant.

STEP6: Packing

When the autoclaving is complete, the AAC blocks are cooled and removed from the autoclave. The finished AAC block will be sent to some sections, including finished product lifting, automatic plate breaking machine, into the transportation and packaging line with stretch film machines, after that, packed AAC blocks can be directly stacked in the finished product yard with forklift. Finally, AAC blocks can be packed and shipped to construction sites or building material suppliers.

ALC Panel plant

Our ACC plant is also suitable for ALC panel manufacturing. ACL panel can be divided into prefabricated panel wall, partition panel, industrial panel, roof and floor panel and other products. The reinforcement of each ALC panel is determined according to the design load, material thickness, length and so on.

The most of production processes of the ALC panel plant are same as that of AAC block plant, the main production process difference between ALC panel and AAC block is that the ALC panel plant has steel processing, assembly of steel mesh and cutting milling groove process.

Steel bar processing(optional step for ALC panel manufacturing process

The processing of steel bars is a unique process in the ALC panels manufacturing process, including steel bar steelmaking, straightening, cutting, welding, coating preparation, coating immersion, and drying. steel bar processing is a vital section, poor process control not only affects the quality of ALC panel, but also directly affects the structure and safety of buildings.

Assembly of steel mesh(optional step for ALC panel manufacturing process

Generally, The process of assembling the steel mesh involves taking the anti-corrosion treated steel mesh and arranging it according to the required size specifications and relative positions as per the production process, then fixing mesh into the mold so as to be poured, which is commonly referred to as “insertion of the pins”.

Cutting milling groove(optional step for ALC panel manufacturing process

In the milling process, the surface waste of the embryo after demolding is scraped off and the side grooves are milled during the transportation of the embryo on the transport cart. The groove milling device adopts an automatically adjustable tool holder, which can better ensure the accuracy of the product.

Ready to Make Money with AAC plant?

What is AAC block? AAC block is short of autoclaved aerated concrete block (or brick). AAC (autoclaved aerated concrete)block, is a lightweight, precast building material made from natural materials such as sand, cement, lime, gypsum, and water. The ALC panel is a similar product from AAC plant. AAC block and ALC panel are strong and durable building material with excellent thermal insulation properties.

Benefits of AAC plant
  • wide range of raw materials, including fly ash, furnace slag, sand, tailings, and stone powder (any one of which can be used).
  • Lower cost: it mainly utilizes local waste resources, which greatly reduces the production cost and increases profits.
  • environmental friendly, no waste is produced during the production process, which complies with environmental protection policies.
  • Customized size, the scale can be large or small, and investors can start small and expand later, achieving zero-risk investment and steady profit.
