Advantages of Small Scale AAC Block Plant
Lower Investment
A key advantage of Small Scale AAC Block Plant is setup cost savings. They need fewer equipment, smaller factory space, and less power/labor than larger facilities, cutting overall investment significantly.
Simplified Management
Automatic Small Scale AAC Block Plants are easy to operate, manage, and maintain. Their automatic batching system boosts feeding efficiency and accuracy-critical for proper ingredient ratios and mixing that impact block quality.
Advanced Technology
The small plant manufacturing meets large-scale plant standards. Using world-leading technology, so as to ensure reliable production quality.
Eco-Friendly Performance
Small AAC block plants use eco-friendly raw materials and produce green end products. With lower capacity than medium/large plants, they have a smaller carbon footprint, fitting green development needs.
Process of Small Scale AAC Block Plant
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 in Small Scale AAC Block 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.
