Abstract

The invention relates to an active mineral waste residue powder production system and a technological process of the system. In the mineral waste residue powder production process, the speed of a conveyed material is adjusted, the air quantity is controlled, and a powder concentrator is optimized and reformed, so that the fineness and the specific surface area of the superfine slag powder are greatly improved; a preparation method of the active mineral waste residue powder is simple; empty grinding and full grinding are prevented, so that running and labor intensity can be lightened, the maintenance cost is reduced, the work environment is improved, the whole grinding process is automatically controlled, and the whole grinding process is optimized; the active mineral waste residue powder production system has the advantages of being reasonable in structure and convenient to operate.

Description

[0001] technical field [0002] The invention belongs to the technical field of non-metallic building materials, and in particular relates to a production system of active slag powder and a process flow thereof. Background technique [0003] According to incomplete statistics, the output of slag powder in my country reached 70 million tons in 2007, and the average selling price was less than 150 yuan / ton. If 10% of the products can be properly processed to D 97 ≤10μm, the value is increased to 1 / 2 of silica fume (about 1500 yuan / ton), which will increase the additional added value (1500 yuan / ton-150 yuan / ton) × (70 million tons × 10%) = 9.45 billion yuan. Reprocessing metallurgical slag to replace silica fume and other resources is not only a new economic growth point in the steel industry, but also a milestone in the search for new raw materials and new modified fillers in the construction engineering, rubber and plastics, asphalt, and waterproof industries. concentrated ...
