A 20,000 m3/year AAC block plant is a compact production line designed to produce approximately 55โ65 cubic meters of AAC blocks per day, depending on the number of working days per year.
This small-scale AAC production line offers everything required to manufacture high-quality AAC blocks while keeping capital cost, land requirements, and operational expenses at a practical level. Whether you are an entrepreneur, a building material distributor, or a local construction company looking to diversify, this plant capacity is the ideal entry point.
Capacity: 20,000 mยณ/year
Autoclaves: 3-4
End product: AAC Block/Panels
Suitable for: small building material suppliers
Standard: Chinese, ASME, EU, and others
Automation Grade: Semi-automatic, Fully Automatic
Brick Material: Fly Ash/Sand
Brick Dimension: customized
Certificate: ISO 9001
Process of 20,000 m3/year AAC Block Plant
Below is the complete workflow used in small AAC plants.
Step 1 โ Raw Material Storage & Batching
Cement, lime, gypsum, fly ash/sand are stored in silos or ground storage and fed into weighing systems.
Step 2 โ Slurry Mixing
Materials are blended into slurry using a high-efficiency mixer. Aluminum powder is added precisely to ensure correct density and strength.
Step 3 โ Casting
Slurry is poured into moulds. Rising and foaming occur naturally during pre-curing.
Step 4 โ Pre-Curing (2โ3 hours)
The โgreen cakeโ becomes semi-solid and ready for demoulding.
Step 5 โ Demoulding & Tilting
The mould is tilted 90 degrees, and the green body is separated from the mould.
Step 6 โ Cutting
The green cake is cut horizontally and vertically into precise block sizes. Block tolerance is usually ยฑ1.5mm to ยฑ3mm, depending on the cutting system.
Step 7 โ Autoclaving (8โ12 hours)
Blocks are loaded into autoclaves and cured using saturated steam at 1.2โ1.4 MPa.
This process ensures high compressive strength (3.0โ4.5 MPa).
Step 8 โ Block Packing
Finished blocks are separated, stacked, and packed for delivery.
Who Is This Plant Suitable For?
The 20,000 mยณ/year model is ideal for:
- First-time AAC investors
- Local construction suppliers
- Small and mid-sized builders
- Block traders turning into manufacturers
- Rural or county-level construction markets
- Regions switching from clay bricks to AAC blocks
It is one of the most popular capacities in Africa, Southeast Asia, South Asia, Middle East small cities, and Latin American developing regions.
Key Features & Advantages of a 20,000 mยณ/year AAC Block Plant
โ Advantage 1 โ Low Investment & Fast Startup
Since the plant size is small, the investment required for:
- equipment
- land
- installation
- foundation
- electricity supply
- worker training
It is significantly lower than larger plants. Many investors recover their investment within 9โ15 months depending on their local market conditions.
It is one of the few AAC plant models that can begin production within 45โ60 days after equipment reach the site.
โ Advantage 2 โ Lower Operating Cost
A 20,000 mยณ/year AAC plant typically requires:
- 5โ10 workers
- smaller autoclaves (ฮฆ2ร20m or ฮฆ2ร22m)
- low energy consumption
- compact land area (6,000โ8,000 mยฒ)
- lower steam and electricity cost
This reduces monthly operational expense and gives higher profit margins.
โ Advantage 3 โ Easy Maintenance & Simple Operation
Because the entire production line is simpler than medium or large plants, the operator learning curve is short. Most customers reach stable production after 1โ2 weeks of training.
Cutting machines, slurry systems, and mould operations are also optimized for small-scale use.
โ Advantage 4 โ Flexible Market Positioning
A 20,000 mยณ plant can serve:
- small cities
- county-level building areas
- rural construction markets
- private developers
- road & bridge projects
- industrial parks
- small real estate clusters
This flexibility makes it suitable for markets where demand is growing but not large enough for high-capacity plants.
โ Advantage 5 โ Lower Risk, Higher ROI
Investors choosing 20,000 mยณ plants often appreciate:
- low production risk
- fast cash flow
- stable daily output
- minimal equipment downtime
- easy spare parts access
This plant size gives excellent costโperformance ratio and is considered the safest starting point for new AAC manufacturers.
Main Equipment in Small Scale AAC Block Plant
Ball Mill: Essential for milling fly ash or sand to the required fineness.โ
Slurry Mixer: Ensures the homogeneous mixing of various raw materials.โ
AAC Moulds: Where the slurry is poured to take the shape of the blocks.โ
Cutting Machines: These include level cutting, vertical cutting, and two – side cutting machines, which accurately shape the blocks.โ
Autoclave: The heart of the process, where high – temperature steam treatment occurs.โ
Ferry Cart: Facilitates the movement of materials and semi – products within the plant.
