Slag aerated concrete equipment is a lightweight porous silicate product made from cement, slag, and sand as the main raw materials, mixed with an air entraining agent (aluminum powder), and processed through processes such as batching, mixing, pouring, pre curing, cutting, steaming, and curing. Because it contains a large number of uniform and small pores after being aerated, it is called slag aerated concrete
Detailed Introduction to the Production Line of Slag Aerated Concrete Blocks
The production line of slag aerated concrete blocks is a complete process line specifically designed to produce aerated concrete blocks using slag as the primary raw material. This production line combines various equipment and technologies to achieve the efficient utilization of waste materials such as slag, producing lightweight, heat-insulating, and energy-saving building materials. The following is a detailed introduction to this production line:
The production line of slag aerated concrete blocks primarily utilizes slag (possibly including other siliceous materials such as fly ash and sand) as the raw material. Through a series of processes, including raw material preparation, batching, pouring, static curing, cutting, autoclaving, and so on, it ultimately produces qualified aerated concrete blocks. These blocks are widely used in the construction industry due to their excellent properties.
Raw Material Processing Equipment:
Receiving Hopper: For receiving and storing raw materials.
Crusher (e.g., Jaw Crusher): For crushing blocky raw materials (such as quicklime, gypsum) to a suitable particle size for subsequent processes.
Ball Mill: For grinding the crushed raw materials to achieve the required fineness.
Batching and Pouring Equipment:
Raw Material Storage Bins: For storing processed raw materials.
Metering Equipment (e.g., Screw Conveyors, Automatic Weighing Scales): For accurately metering raw materials to ensure accurate blending ratios.
Mixer: For mixing the metered raw materials with water, foaming agent (e.g., aluminum powder), and other additives to form a slurry.
Pouring Machine: For pouring the mixed slurry into molds.
Static Curing and Cutting Equipment:
Static Curing Chamber: Provides optimal environmental conditions (e.g., temperature, humidity) for the slurry to fully react and form a hardened block.
Cutter: For cutting the cured blocks into specified sizes.
Stacking and Autoclaving Equipment:
Autoclave Car: Carries the cut blocks into the autoclave for curing.
Autoclave: Cures the blocks under high temperature and pressure to further harden them and achieve the designed strength.
Finished Product Discharge Equipment:
Discharge Equipment (e.g., Electric Hoists, Discharge Hooks): Removes the cured blocks from the autoclave and prepares them for subsequent stacking, packaging, etc.
Dust Removal Equipment:
Dust Collectors (e.g., Single-machine Dust Collector for Jaw Crusher, Roof Dust Collector): Collects and treats dust generated during the production process to protect the environment.
Electrical Equipment:
Batching Control System, Low-voltage Control Cabinet, Automatic Control System, etc.: For automating and monitoring the entire production line.
Raw Material Preparation: Crush and grind the slag and other raw materials to achieve the required fineness.
Batching: Mix the processed raw materials, cement, foaming agent, and other additives in specific proportions.
Pouring: Pour the mixed slurry into molds.
Static Curing: Allow the slurry to fully react and form a block in the static curing chamber.
Cutting: Cut the cured blocks into specified sizes.
Autoclaving: Cure the cut blocks in an autoclave under high temperature and pressure.
Finished Product Handling: Remove the cured blocks from the autoclave and prepare them for stacking, packaging, etc.
Slag aerated concrete blocks are lightweight, heat-insulating, and energy-saving, meeting the national requirements for environmentally friendly and energy-efficient building materials. Additionally, this production line effectively utilizes waste resources such as slag, promoting resource recycling and sustainable development.
In summary, the production line of slag aerated concrete blocks is a comprehensive process line that encompasses raw material processing, batching and pouring, static curing, cutting, autoclaving, and finished product handling. The aerated concrete blocks produced through this line exhibit excellent properties and have broad application prospects.
