AAC Block Manufacturing Process
Raw material process โ Batching and Mixing โ Pouring โ Static pre-curing โ Cutting โ Autoclaving Curing โ 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 175-200ยฐC 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.
Machinery in AAC Block Manufacturing
1. Raw Material Handling Equipment
Sharli tegirmon: Used for finely crushing siliceous and calcareous materials such as sand, fly ash, and lime.
Jag' maydalagich: Crushes bulky raw materials (such as limestone) in preparation for subsequent grinding.
2. Mixing and Batching System
Mikser: Commonly used is a vertical shaft mixer, which uniformly mixes siliceous and calcareous materials, gas-generating agents (aluminum powder), and conditioning agents (gypsum) to ensure consistent block quality.
Batching System: Accurately measures and controls the raw material input ratio to ensure that block properties such as strength, density, and porosity meet specified standards.
3. Molding and Casting Equipment
Molds: Made of steel and designed to fit the block size, they hold the mixed slurry and shape it.
Pouring Equipment: Ensures smooth transfer of slurry to the mold, preventing air bubbles and uneven distribution.
4. Curing and Hardening Equipment
Pre-curing Chamber: Allows the slurry to initially solidify and strengthen in a controlled temperature and humidity environment, preparing it for subsequent processing.
Avtoklav: A large pressure vessel that uses high-temperature, high-pressure steam curing to induce chemical reactions in the raw materials, forming a strong and stable structure and enhancing the strength and durability of the blocks.
5. Cutting and Finishing Equipment
Cutting Machine: Cuts the pre-cured blocks horizontally and vertically (e.g., using a wire saw) to ensure dimensional accuracy.
Finishing Equipment: Optimizes the surface smoothness of the blocks through processes such as grinding to meet both aesthetic and functional requirements.
Factors Effecting Choosing the AAC Blocks Machinery
Choosing the right AAC Blocks Manufacturing Machinery is crucial for a successful production operation. Consider the following seven key factors:
1. Production Capacity
Determine your target market’s daily/hourly production output and select equipment that matches this output.
2. Level of Automation
- Fully automated AAC Blocks Manufacturing Machinery reduces manual intervention, increases production, and reduces labor costs, making it suitable for large-scale production.
- Semi-automated AAC Blocks Manufacturing Machinery requires more manual intervention but is more cost-effective, making it suitable for smaller-scale production.
3. Quality Control
Equipment must be reliable, including automated weighing and batching systems, precision mixing systems, and precise temperature and pressure control during the curing process. These features ensure consistent quality for each block.
4. Energy Efficiency
Energy efficiency directly impacts operating costs and the environment. Selecting equipment that optimizes energy consumption ensures economical and environmentally friendly production.
5. Maintenance and Support
Regular maintenance is crucial for the long-term, stable operation of your equipment. Choosing equipment from a reputable manufacturer ensures reliable technical support and timely availability of spare parts. Ease of maintenance is also important.
6. Equipment Durability
Highly durable equipment reduces maintenance downtime. Consider: high-quality materials and robust construction, and the manufacturer’s warranty.
7. Ease of Use
Easy-to-use equipment reduces operator learning curve and improves efficiency.
