Medium Fly Ash AAC Block Plant?
A Medium Fly Ash AAC Block Plant is a production line capable of producing 20,000–50,000 cubic meters of AAC blocks per year, offering a practical balance between production capacity and investment. This type of plant is suitable for:
- First-time investors entering the AAC block industry
- Traditional block manufacturers upgrading operations
- Regional housing or infrastructure projects needing reliable block supply
Medium plants provide scalable production, consistent quality, and efficient operation, making them an attractive option for projects that require both reliability and cost-effectiveness.
Fly Ash in AAC Production
Fly ash, a byproduct of coal combustion, is rich in silica and alumina. In AAC block production, it serves as a pozzolanic material, improving strength while reducing cement consumption. Compared to sand-based AAC blocks, fly ash AAC blocks offer consistent quality, lower material costs, and environmental benefits, making them a preferred choice for medium-capacity production.
Medium Fly Ash AAC Block Production Process
The production process is mature, streamlined, and designed for consistent, high-quality output:
- Préparation des matières premières – Fly ash, cement, lime, gypsum, and aluminum powder are crushed, screened, and blended.
- Mixing & Slurry Preparation – Raw materials are mixed into a homogeneous slurry. Formula adjustments accommodate fly ash variability.
- Pouring & Pre-Curing – Slurry is poured into molds and lightly pre-cured.
- Système de coupe – High-precision cutting machines ensure uniform block size.
- Autoclavage – Steam curing in an autoclave produces strong, durable blocks.
- Stacking & Packaging – Finished blocks are stacked and prepared for delivery. Semi-automatic or fully automatic stacking options are available.
Core Equipment Configuration
The choice of equipment is critical for production efficiency and block quality. Key components include:
| Equipement | Fonction |
|---|---|
| Ball Mill / Fly Ash Processing System | Prepares raw materials for mixing |
| Mélangeur | Ensures homogeneous slurry for consistent block quality |
| Molds & Tilting Crane | Shapes and handles pre-cured blocks |
| Machine à découper | Precision cutting of blocks to exact dimensions |
| Autoclave | Steam curing for final strength and dimensional stability |
| Boiler System | Supplies steam for autoclaving |
Automation can range from semi-automatic to fully automatic systems, depending on budget and production goals. Proper configuration directly affects production output, block quality, and maintenance costs.
Advantages of Fly Ash as the Primary Material

Fly ash AAC blocks offer several advantages:
- Cost-effective – fly ash is low-cost and widely available.
- Environmentally friendly – reduces industrial waste and lowers emissions.
- Regulatory support – many regions encourage fly ash usage.
- High-quality output – lightweight, fire-resistant, and strong blocks suitable for various building applications.
These benefits make fly ash an ideal choice for medium-scale AAC block plants.
