Fly ash AAC production line

Introduction of fly ash AAC production line 1. Storing and supplying of raw materials of AAC blocks: All raw materials are carried into factory by trucks, such as Fly ash, sand, lime and cement and so on are gathered in specified raw materials field waiting for use. Sack of cement and bulk cements are stored in cement warehouse. Chemicals and aluminium powder are separately kept in chemical bin. When used, these raw materials are carried into workshop respectively. 2. Processing of raw materials: Fly ash, sand, lime and cement are sent into ball mills by vibration feeders and screw conveyor. Then fine powders of fly ash, sand, lime and cement are pumped into slurry tank. Quick lime is sent by vibrating feeder and screw conveyor into jaw crusher to smash. Smashed lime is sent into lime silo by bucket elevator and then is transported into ball mill by screw conveyor. Fined materials are sent into proportion bin by screw conveyor and bucket elevator. 3. Aerated block ingredients, pouring and casting Fly ash (or sand or stone powder) and waste slurry are measured in measuring tank. After the measuring and mould in their place, slurry stirring begins. Slurry temperature should reach about 40° C. 4. Aerated block's procuring and cutting The features of AAC blocks Compared with traditional clay brick, AAC block is the most economical and eco-friendly building material. As a kind of new building material, AAC block will be the ideal choice for all kinds of modern building.
