Advantages of a 120,000 m3/Year AAC Block Making Line

Investors choose the 120,000 m³ configuration because it provides high output, stable quality, and cost efficiency. Key advantages include:

1. Optimal Cost–Output Balance

Compared with small 30,000–80,000 m³ plants, the 120,000 m³ line benefits from:

lower production cost per cubic meter
higher automation level
better labor efficiency
stronger competitiveness in local markets

For many investors, this is the capacity that maximizes profit without risking over-production.

2. High Block Strength & Stable Quality

Our production line achieves:

3.5–5.0 MPa compressive strength
uniform density (500–650 kg/m³)
accurate block dimensions
excellent curing consistency due to advanced autoclave control

High-quality blocks improve market acceptance and resale value.

3. Energy-Efficient Autoclave System

A key feature of our 120,000 m³ plant is the low-energy curing system:

optimized steam distribution
faster heat transfer
lower fuel consumption
stable pressure holding (1.2–1.3 MPa)

This reduces operating cost significantly.

4. Flexible Raw Material Options

Common local materials include:

river sand
crushed sand
fly ash
cement
lime
gypsum
aluminum powder

Adaptable formulation allows operation in diverse regions such as Malaysia, Indonesia, Kenya, Saudi Arabia, and Mexico.

5. Fully Modular & Expandable Design

The line can later be expanded to 150,000–200,000 m³/year by adding:

extra molds
additional autoclaves
robotic cutting upgrades

This protects your long-term investment.

120,000 m3/Year AAC Block Making Line Process

Raw material process → Batching and Mixing → Pouring → Static pre-curing → Cutting → Autoclaving Curing → Finished product Processing

1. Raw Material Processing: Sand is crushed and ground to the desired fineness. Cement, lime, and gypsum are stored in silos, and aluminum powder is mixed with water to form an aluminum slurry.

2. Batching and Mixing: The various raw materials are weighed according to precise proportions and then thoroughly mixed in a mixer to form a uniform slurry.

3. Pouring: The mixed slurry is poured into steel molds. The size and shape of the molds can be designed to meet the desired block specifications.

4. Static Pre-curing: The molds containing the slurry are transported to a pre-curing area where the slurry gradually hardens under suitable temperature and humidity conditions to achieve initial strength. This process typically takes several hours.

5. Cutting: After the slurry is pre-cured, it is cut into the desired size and shape using high-precision cutting equipment like steel wire or blades.

6. Autoclave Curing: Blocks are placed in an autoclave and cured for several hours at temperatures of 175-200°C and pressures of 10-15 bar, significantly enhancing the blocks’ strength and durability.

7. Finished Product Processing: After autoclave curing, the blocks are removed from the autoclave and transported to a storage area. After inspection and packaging, they are ready for shipment.

Raw Materials of AAC block

Cement (Portland Cement): Acts as a primary binder, providing strength and durability to the blocks. Typically, 43 or 53-grade OPC is used.
Fly Ash or Sand: Serves as the main siliceous material. Fly ash, a byproduct of coal-fired power plants, is an eco-friendly alternative to sand, providing the necessary silica content.
Lime: A key calcareous material that reacts with other components to form the binding matrix and contributes to the chemical reactions during production.
Gypsum: Added in small quantities to regulate the setting time and improve the workability of the mix.
Aluminum Powder or Paste: Functions as a foaming agent. It reacts with lime and water to produce hydrogen gas, creating the characteristic porous, lightweight structure.
Suv: Essential for the hydration of cement and lime, and to facilitate the chemical reactions necessary for the setting and hardening of the blocks.

These materials are carefully proportioned and mixed to form a slurry, which is then cast, pre-cured, cut, and finally autoclaved to produce the finished AAC blocks.

Main Equipment in 120,000 m3/Year AAC Block Making Line

What Is An AAC Block？

Autoclaved aerated concrete (AAC) blocks are a lightweight, porous, high-strength new building material.

The unique internal pore structure provides lightweight, high strength, thermal insulation, fire resistance, and sound insulation.

It is an ideal choice for achieving energy-saving and structural safety in buildings.

Application of AAC Block

Civil Buildings: Used in internal and external walls, floor slabs, roof slabs, etc. of residential buildings to reduce building weight and improve seismic performance.

Commercial Buildings: Suitable for non-load-bearing walls of shopping malls, hotels, office buildings, etc., with good thermal insulation and sound insulation effects to enhance building comfort.

Industrial Buildings: Served as wall and partition materials for factories and warehouses, meeting the special requirements of industrial production for building materials.

Special Buildings: Widely applied in hospitals, schools, gymnasiums and other places due to their excellent fire resistance and environmental protection properties.
