AAC Block Making Machine

This solution will focus on AAC (aerated concrete block) equipment, providing a detailed explanation of the equipment's core working principles, equipment configuration options for different production capacities, and answering key questions you may encounter in equipment selection and production operation. It will also showcase our core advantages and comprehensive service guarantees to help you efficiently implement your AAC block production project.

I. Core Working Principle of the Equipment

The core function of AAC (aerated concrete block) equipment is to transform low-cost, readily available raw materials (fly ash, sand, lime, cement, etc.) into lightweight, high-strength, and environmentally friendly AAC (aerated concrete block) blocks through a standardized process.

1. Raw Material Compatibility: Using fly ash, sand, lime, and cement as core raw materials, supplemented with appropriate amounts of gas-generating agents and regulators (adjustable flexibly according to local raw material resources to reduce raw material costs);

2. Precise Proportioning: An intelligent batching and metering system automatically measures each raw material according to a preset formula, ensuring precise proportions (error ≤ ±0.5%), guaranteeing block quality from the source;

3. Mixing and Gas Generation: Raw materials enter a dedicated mixing unit, where they are thoroughly mixed with the gas-generating agent. Simultaneously, a heating device regulates the slurry temperature to ensure uniform gas generation, forming a fine, porous slurry;

4. Casting and Curing: After the slurry is poured into the mold frame, it is placed in a constant temperature and humidity curing chamber for 2-4 hours of slow solidification, forming a solid block with sufficient strength and no cracking;

5. Precise Cutting: According to your required block specifications (e.g., 600×200×100mm), a high-precision cutting unit automatically cuts the blocks, resulting in a smooth surface without chipping, with a dimensional error ≤ ±2mm;

6. High-Temperature Steam Curing: The cut green bodies are placed in an autoclave and steam-cured for eight hours at 180℃ and 0.8-1.0 MPa to fully solidify the green bodies, ultimately forming AAC (aerated concrete) blocks that meet the requirements.

7. Finished Product Processing: After demolding, breaking into blocks, and packaging, the finished products are ready for warehousing or transportation. Waste generated during cutting and breaking can be recycled and reused, reducing raw material waste.

Core Advantages: The entire production process produces no toxic gases or waste residue emissions and can utilize large quantities of industrial waste (fly ash, slag, etc.), complying with environmental policies and reducing raw material costs.
