The production of titanium dioxide by sulfuric acid method is a mature production method, and the raw materials used are ilmenite or titanium slag. Ilmenite concentrate generally has a relatively coarse particle size and a small specific surface area. The contact area with sulfuric acid during acid hydrolysis is small and it is difficult to be effectively decomposed by sulfuric acid. Therefore, it must be ground finely before use to increase the reaction contact surface so that the acidolysis reaction can proceed normally. According to the acid hydrolysis process requirements, use Raymond mill to grind the titanium concentrate to a certain particle size. Guilin Hongcheng is a titanium ore Raymond roller mill manufacturer. Today I will introduce to you the titanium concentrate crushing process.
Titanium concentrate crushing process: Titanium concentrate is sent to the storage hopper by a bucket elevator, and then the raw ore is quantitatively, evenly and continuously sent to the Raymond mill for crushing by the feeding device. The crushed materials are brought out by the analyzer by the air flow blown by the blower. The coarse particles are blocked and then fall into the crushing area and then return to the Raymond mill to form a closed loop. The separated material is discharged from the lower part of the cyclone separator, enters the mineral powder intermediate storage tank, and is then sent to the mineral powder storage tank by the pulse pneumatic conveying pump for acid hydrolysis. Part of the circulating air is removed by the bag dust collector and then emptied, and the dust collected fly powder enters the intermediate storage tank of the mineral powder.
The mineral powder participating in the acidolysis reaction must not only reach a certain fineness, but also have a narrow and uniform particle size distribution. Only in this way can a higher acidolysis rate be obtained and a titanium sulfate liquid that meets the process requirements can be obtained. The general mineral powder fineness requirement is: 325 mesh sieve residue ≤ 1. 5%. Therefore, the Raymond mill that meets the processing requirements has become a commonly used equipment in the titanium concentrate crushing process.
As a titanium ore Raymond mill manufacturer, Guilin Hongcheng's titanium ore Raymond mill has been widely used in the market and has a good reputation. However, with the increase in the production capacity of titanium dioxide enterprises, the production capacity of titanium ore Raymond mill has gradually been unable to meet the needs of titanium concentrate crushing and processing. Therefore, Guilin Hongcheng developed and produced the HLM series of titanium ore vertical mills for large-scale production. In recent years, it has also become a popular model purchased by titanium dioxide companies. If you have titanium concentrate crushing project needs, please leave us a message for equipment details.
