What is the Cost of a Mini AAC Plant?
The cost of a Mini AAC Plant varies widely and depends on several factors. Generally speaking, the total investment for a small AAC production line with an annual capacity of 300,000-100,000 cubic meters ranges from $250,000 to $800,000.
- Manual production line in India/Southeast Asia: $250,000–400,000
- Semi-automatic production line in China: $350,000–550,000
- Fully automated production line for European and American CE standards: $600,000–800,000
Mini AAC Manufacturing Process
1. Raw material process
The process begins with the treatment of raw materials. Fly ash or sand is transported via conveyor belts to a ball mill for milling. After milling, the resulting slurry is pumped into a slurry storage tank for further use.
2. Dosing and Mixing
Lime and cement are conveyed to dry powder measure scales, where they are accurately measured. The slurry from the storage tank is also pumped to an automatic scale. These measured materials are then mixed together in a mixer and poured into molds.
2. Moulding, Rinsing, and Pre-curing
The mixed slurry is poured into molds, which are then placed in a curing room maintained at 50 – 70 °C. After 2 – 3 hours of pre – curing, the blocks start to solidify.
3. Demoulding and Cutting
A reversal crane is used to carry the mold and block to a cutting cart for demoulding. The cutting cart then transports the block to a series of cutting machines, including level cutting, vertical cutting, and two – side cutting machines. The top waste material is also removed at this stage.
4. Autoclaving
The cut semi-products are grouped in front of the autoclave. A hoisting machine or dragger then moves the steam trolleys loaded with the blocks into the autoclave for steam treatment, which typically takes 10 – 12 hours. This process significantly enhances the strength and durability of the AAC blocks.
5. Packing and loading
Once the blocks are out of the autoclave, a separating machine is used to separate them layer by layer. The finished products are then clamped by a carry hanger and placed on a packaging line on wooden pallets. Finally, forklifts transport the packaged products to the storage yard for stacking according to specifications.
Main Equipment Used in Mini AAC Plant
Ball Mill: Essential for milling fly ash or sand to the required fineness.
Slurry Mixer: Ensures the homogeneous mixing of various raw materials.
AAC Moulds: Where the slurry is poured to take the shape of the blocks.
Cutting Machines: These include level cutting, vertical cutting, and two – side cutting machines, which accurately shape the blocks.
Autoclave: The heart of the process, where high – temperature steam treatment occurs.
Ferry Cart: Facilitates the movement of materials and semi – products within the plant.
Advantages of Mini AAC Block Plant
Less Investment: As mentioned earlier, it requires fewer equipment, a smaller factory area, and less power supply and human resources compared to larger – scale plants. This significantly reduces the initial investment and ongoing operational costs.
Easy Management: The automatic mini AAC plant is user – friendly, easy to operate, manage, and maintain. The adoption of an automatic batching system improves the efficiency and accuracy of material feeding, which is crucial for maintaining the quality of AAC blocks.
Upgraded Technology: Despite its small scale, the manufacturing process adheres to the same high standards as larger – scale plants. This ensures that the AAC blocks produced are of the highest quality, with excellent thermal insulation, fire – resistance, and lightweight properties.
Environmental Friendly: The raw materials used in AAC production are eco – friendly, and the end – product is also sustainable. Moreover, due to its lower production capacity compared to medium and large AAC plants, the carbon footprint of a mini AAC plant is smaller.

Tips for the Layout of Mini/Small AAC Block Plant
- The raw material yard is located near the road to reduce repeated handling.
- An I-shaped layout is adopted to ensure one-way movement of mold carts.
- Parallel autoclaves share a single boiler to reduce piping.
- The stockpiling and loading/unloading areas are located on the same side, with a forklift turning radius of ≤5 meters.
- A 10m x 20m area is reserved for the second phase of expansion—adding two autoclaves to double production capacity.
