The HLM cement mill use of sintering red mud to produce cement is an environmentally friendly and high-efficiency method to solve a large number of waste slag emissions from aluminum smelting enterprises. After the red mud is dealkalized, it becomes low-alkali red mud by adding sandstone and limestone, and calcined at a high temperature of 100-150 degrees. Cement is formed, then fly ash and gypsum are mixed in a certain proportion, and the powder is fully mixed and ground to obtain cement powder, which can be packaged and sold.
1. Material table of cement produced by sintering red mud
The materials used in the production of cement from red mud by sintering are lime, modifier, sandstone, limestone, fly ash and gypsum.
2. Process flow of sintering red mud to produce cement
The process flow of sintering red mud to produce cement is as follows:
Red mud (dealkalinization modification) -> calcination of raw meal mixture -> smelting of raw meal mixture -> finished cement
3. Cement grinding equipment: HLM cement mill
Guilin Hongcheng Cement Milling Equipment HLM Cement Mill can grind the raw materials (lime, sandstone, limestone, fly ash and gypsum, cement) for the production of cement by sintering red mud. Around 100-325 mesh, cement is produced. There have been mature cases, and the equipment has been put into production in many cement factories.
