Abstract: The production methods of titanium dioxide mainly include sulfuric acid method and chlorination method. The sulfuric acid method is to use titanium concentrate or acid-soluble titanium slag to react with sulfuric acid for acid hydrolysis to obtain a titanyl sulfate solution, which is hydrolyzed to obtain a metatitanic acid precipitate; and then enter the rotary kiln to calcine to produce TiO2. The sulfuric acid method is mainly operated by the batch method, and the production device has great flexibility, which is beneficial to start and stop and load adjustment. According to the material characteristics of titanium dioxide, on the basis of digestion and absorption of foreign advanced equipment and technology, the self-developed fast rotary flash dryer has been successfully applied in the drying of titanium dioxide. Under the action of centrifugal force (the top has a classification device), products with a certain degree of dryness and fineness are blown out of the classification device, and the materials are quickly dried in the process. In recent years, China's titanium dioxide industry has grown several times in terms of capacity, output and market demand. The titanium dioxide industry has ushered in its prosperous period. At the same time, the production of rutile titanium dioxide has increased. The speed is also accelerated, so the selection of titanium dioxide drying equipment has become the top priority, which is the key to affecting the qualification of the material. Based on the material characteristics of titanium dioxide, on the basis of digestion and absorption of foreign advanced equipment and technology , The self-developed fast rotary flash dryer has been successfully applied in the drying of titanium dioxide. The flash dryer is mainly composed of an air inlet system, a heating system, a feeding system, a drying host, a dust collecting system, an exhaust system, a control system, etc. When working, the wet material enters the drying chamber by the screw feeder. The material meets the hot air rotating at a high speed in the drying chamber. The fine powder material is carried by the hot air to the upper end of the drying chamber. The material that cannot be taken down falls at the bottom of the drying chamber. Being crushed by the crushing device at the bottom, the material is quickly dispersed, and the contact area between the material and the hot air increases rapidly. Under the action of centrifugal force (the top has a classification device), products with a certain degree of dryness and fineness are blown out of the classification device, and the materials are quickly dried in the process. As a new type of equipment, flash drying has been widely used in the titanium dioxide industry in recent years. At present, the commonly used models for the titanium dioxide industry are 1400 and 1600 type flash dryers. In the titanium dioxide industry, the company will, as always, adhere to technological innovation, continuously improve the company's innovation ability, and contribute to the sustainable development of the titanium dioxide industry and the drying industry. nordic coffee table,living room table,Stainelss Steel Coffee Table Kumusi (Dongguan) Furniture Co., Ltd. , https://www.kcoffeetable.com
