This section prepares and stabilizes the raw materials used for AAC production. It covers crushing, grinding, storage, conveying, agitation, metering, and dust control for materials such as silica sand, fly ash, lime, cement, gypsum, aluminum powder, and water.

Its main role is to create a reliable foundation for later batching, pouring, and curing. Stable raw material preparation supports consistent slurry quality, accurate dosing, smoother section-to-section coordination, and more predictable product performance.
