ALC Production Line

The production of aerated concrete requires high standards in terms of raw material batching, pre curing process monitoring, and subsequent production process control. Maxport Machinery has many years of rich experience and has incorporated new automatic control algorithms into the control unit, effectively ensuring the high quality of the products.

Maxpor Machinery has many advanced technologies in the production of concrete equipment, providing ample options for complete sets of equipment, individual machines, as well as all services and production support. At the same time, this has also won a decisive advantage in the customer's market.

Manufacturing personalized equipment with standardized components

In order for each production equipment to achieve economic success, it must have good design, which first considers the specific site conditions and combines them with long-term development needs. Under this concept, Maxpor engineers will select the corresponding equipment specifications, production capacity, and arrange production equipment and processes. Of course, the entire turnkey production line is designed by Maxpor engineers and optimized using standard component combinations. The complete set of equipment produced using these standard components has shortened delivery time while meeting customer needs.

Characteristics of ALC production line production process:

(1) Processing of raw materials

The main raw materials for autoclaved ALC board are sand, cement, lime, gypsum, aluminum powder, and steel bars. Before production is determined, these raw materials should be transported to the factory by truck, and the incoming block shaped quicklime should be crushed and powdered before storage. During storage, attention should be paid to ensuring the dryness of the raw materials.

(2) Reinforcement processing and mesh cage assembly

Reinforcement processing is a unique process in the production of ALC panels, including rust removal, straightening, cutting, welding, coating preparation, coating impregnation, and drying of reinforcement. Mesh cage assembly is the process of assembling steel mesh that has undergone anti-corrosion treatment according to the required dimensions and relative positions of the process, and then placing it into a mold to fix it before pouring.

(3) Raw material coordination

In the production process, batching is a key link that directly affects the ratio of active ingredients between raw materials, the viscosity and flowability of the slurry, and whether it is suitable for aluminum powder gasification and normal hardening of the body. Therefore, it should be given sufficient attention. Ingredients are the measurement, temperature, and concentration adjustment of various raw materials that have been prepared and stored for use.

(4) Pouring and mixing

The pouring process is to mix the materials from the previous batching process into the mixer after measurement and necessary adjustment, to produce a slurry that meets the time, temperature, and consistency requirements of the process. Then, it is poured into the mold through the pouring mixer. After pouring is completed, the steel mesh cage is placed in the mold car, and then the mold car enters the static chamber at around 55 degrees for pre curing. After about 3 hours of pre curing, the slurry undergoes a series of physical and chemical reactions in the mold, generating bubbles, causing the slurry to expand, thicken, and harden. This process is an important step in whether a good pore structure can be formed.

(5) Static cutting

After the billet is foamed and stopped to meet the cutting requirements, the mold is transferred to the cutting area. The mold is separated by a flipping machine and the billet is flipped 90 degrees and placed on a steam curing cart. Then, the billet is cut and grooved on the side and horizontally and vertically divided through the cutting process to meet the appearance size requirements. The cutting work can be mechanized or manually operated, which directly determines the appearance quality and some internal quality of ALC board products.

(6) Steam curing

The process of sending the cut billet into a steam pressure vessel for steam pressure curing by a shuttle truck requires a temperature above 200 ℃. Therefore, a steam pressure vessel with good sealing performance is used, and saturated steam with a certain pressure is introduced for heating. The billet undergoes a hydrothermal reaction for about 12 hours under high temperature and high pressure conditions, so that the ALC board has certain strength and physical and chemical properties.
