The production of titanium dioxide by sulfuric acid method is a mature production method, and the raw material used is ilmenite or titanium slag. Titanium concentrate generally has relatively coarse particle size, small specific surface area, and small contact area with sulfuric acid during acidolysis, so it is not easy to be effectively decomposed by sulfuric acid. Therefore, it must be ground finely before use to increase the reaction contact surface, so that the acid hydrolysis reaction can proceed normally. According to the technical requirements of acid hydrolysis, use Raymond mill to grind the titanium concentrate to a certain particle size.
Guikuang Machinery is a manufacturer of titanium ore Raymond mill and titanium ore vertical roller mill. The following is an introduction to the crushing process of titanium concentrate:
The grinding process of the titanium concentrate grinding mill: the titanium concentrate is sent to the storage hopper by the bucket elevator, and then the raw ore is quantitatively, uniformly and continuously sent to the titanium ore Raymond mill for grinding by the feeding device. The pulverized material is taken out by the analyzer by the air flow blown by the blower, and the coarse particles are blocked and fall into the pulverizing area and return to the Raymond mill to form a closed-circuit cycle. The separated materials are discharged from the lower part of the cyclone separator and enter the intermediate storage tank of mineral powder, and then sent to the mineral powder storage tank by the pulse pneumatic conveying pump for acid hydrolysis. Part of the circulating air is evacuated after being dedusted by the bag filter, and the dust-collected fly powder enters the intermediate storage tank of mineral powder.
The mineral powder participating in the acid hydrolysis reaction must not only reach a certain fineness, but also have a narrow and uniform particle size distribution, so as to obtain a higher acid hydrolysis rate and obtain a titanium sulfate solution that meets the technological requirements. The general requirements for fineness of mineral powder are: 325 mesh sieve residue ≤ 1.5%. Therefore, the titanium ore Raymond mill that meets the processing requirements has become a common equipment for the grinding process of titanium concentrate. Titanium ore raymond mill is a balance wheel grinder, which relies on the centrifugal force of the balance wheel to squeeze and grind the steel ring to achieve the purpose of crushing materials. Guikuang Machinery, as a titanium ore raymond mill manufacturer, our 4R3216 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 difficult to meet the needs of titanium concentrate crushing and processing.
