Since 2000, with the rise of the domestic white carbon black market, the company seized the opportunity to invest a lot of manpower and material resources in the production and installation of white carbon black complete production lines, and cooperated with major technical colleges and exchanges with industry experts. After more than ten years of hard work, we have mastered mature technology in the complete production line of 5000-20000t/a silica, and have successively undertaken the production and installation of several sets of drying and reaction equipment.
In recent years, 10,000-ton-level production devices have developed rapidly, and dozens of devices are currently in production, thus creating favorable conditions for improving product quality and reducing raw material and power consumption. At present, the production technology of general white carbon black of China's advanced manufacturers has reached the international advanced level, and has a good cost advantage, which has led to a large increase in the export volume of general white carbon black in China in recent years.
The complete production line of white carbon black starts from the reaction section, press filtration, beating, centrifugal spray drying (pressure spray drying) to finished product packaging.
Main features of the drying system
◆ Low outlet air temperature and high energy utilization rate: Due to the enlargement of the tower body and the appropriate aspect ratio, the outlet air temperature is lower than that of ordinary white carbon black equipment, and the outlet air temperature is about 90 degrees. For white carbon black equipment, reducing the outlet air temperature by 5 degrees will increase the energy utilization rate by about 2.5%. For large-scale production equipment, the benefits are considerable.
◆ Perfect process: the system includes the whole process of beating, drying, bag filtration, cooling and screening. The operation continuity is good, the equipment runs stably, the final product is cooled by air, the moisture content is more stable, the product temperature is lower than 60 degrees, and the product is exported The location is flexible, which is more conducive to connecting the automatic packaging mechanism.
