Zircon sand is also known as zircon sand and zircon. It is a mineral component mainly composed of zirconium silicate (Zr 2 SiO 4 ). Pure zircon sand is a colorless and transparent crystal. Due to the difference in origin and the type and quantity of impurities, the color of zircon sand is yellow, orange, red, brown, etc., and its crystal structure belongs to tetragonal system.
The following is a distribution map of zircon sand:
The zircon sand dressing process diagram can be seen in the following figure. The main process is: the original ore is sieved through a vibrating screen, and the sieved material is directly sorted out by the gravity ore dressing equipment to produce the finished concentrate. The unqualified product is ground by a ball mill and then passed through gravity. The finished product of the concentrate zircon sand can be obtained by sorting. Zircon sand treatment is simple and mature.
The following are three preparations for zircon sand grinding, for reference only:
1. The zircon sand wet grinding process has the best sanitary condition, but in the actual production of the factory, especially when the work is suddenly interrupted (blackout, machine repair), the zircon sand is too large, it is easy to precipitate, and it is not easy to float. , often affects the quality of the product, and even makes the milled product unqualified, seriously affecting the economic benefits of the enterprise.
2. Zircon sand dry ball milling is characterized by simple process, no need to evaporate water and reduce water pollution. The particle size range is good.
3. Zircon sand dry-wet grinding mixing process. The process is to dry the zircon sand and the prepared composite grinding aid for a period of time. After the coarser material particles reach a certain fineness, add water and assist grinding. The agent is wet-milled, and the method works best in the same ball milling time. The disadvantage is that the addition of water-enhancing grinding aid is added during the ball milling process.
