Summary: | A production and preparation technology for first-grade coal ash is characterized by comprising the steps of raw ash preparing, semi-finished product machining, raw ash and semi-finished product mixing and finished product separating. The production and preparation technology has the advantages that damage to microscopic particles of the coal ash is reduced, the loading burden of a grinding body and the load of a mill are lowered, the content of harmful chromium ions in products is lowered, the production cost is lowered, and energy conservation and environmental protection are realized. |
