The project is a science and technology project initiated by the Ministry of Land and Resources of Hebei Province. It was completed by the Laboratory of Hebei Province Geology and Minerals Center. In January 2008, it was approved by the Hebei Provincial Department of Land and Resources. Chengde Vanadium and Titanium ultra-lean magnetic iron ore is the famous temple of a sub-type vanadium-titanium magnetite minerals, as well as success in recent years to develop new mineral utilization in Hebei Province. In addition to iron, ultra-depleted vanadium-titanium magnetite is accompanied by minerals such as vanadium (V), titanium (Ti) and phosphorus (P). However, in the development and utilization of mines, most mining enterprises have not comprehensively recycled and associated minerals such as vanadium, titanium and phosphorus. Only a few mining enterprises have comprehensively recycled and utilized resources such as titanium and phosphorus, and the comprehensive recycling rate is low. Recycled resources such as vanadium, titanium and phosphorus are difficult to recycle. In order to promote the comprehensive recycling of resources, in 2007, the Planning and Design Institute of Chengde City Land and Resources Bureau cooperated with the Laboratory of Hebei Province Geology and Minerals Center to carry out and complete the vanadium and titanium of ultra-depleted vanadium-titanium magnetite (tailings) in Chengde City, Hebei Province. Research on the comprehensive recycling of phosphorus and other elements. On the basis of the comprehensive recovery process of the associated elements of the “Da-Miao†vanadium-titanium magnetite, the research work first uses optical microscopy, scanning electron microscopy, spectral analysis, chemical analysis, phase analysis and electron probe analysis. Comprehensive analysis and analysis of ore material composition, ore properties and ore processing technology; selected 8 representative mining areas, for the nature of ore, using the difference in physicochemical properties such as mineral magnetization coefficient, specific gravity and floatability, using magnetic separation, floating and reselection methods such election, magnetite, ilmenite, apatite and optional mineral comparative tests were summarized recommend the single integrated iron and selected from the group selected from phosphorus, titanium election process, i.e., "coarse separator , coarse concentrate re-magnetization - shaker - strong magnetic separation titanium process" or "original - magnetic separation - flotation - titanium recovery process". The magnetite in the ore can be recovered by the weak magnetic method; vanadium has no separate minerals, but is present in the vanadium-titanium magnetite in the form of isomorphism, and is recovered by smelting; the single crystal of ilmenite can be obtained by strong magnetic method or heavy The magnetic flotation combined process is recycled; the apatite is floatable and can be directly recovered from the iron ore tailings by flotation. The process provides reference and reference for the beneficiation process to improve the comprehensive utilization level of titanium, phosphorus and other elements in the ultra-lean vanadium-titanium magnetite resources. At the same time, based on the current iron ore and phosphate geological exploration specifications, the ore is proposed based on the analogy analysis. The lowest industrial indicators for the comprehensive utilization of intermediate components such as titanium and phosphorus are recommended. Through research, optional industrial experiments and mine production, it is shown that the selection of titanium and phosphorus-selecting technology from tailings is feasible and economically reasonable. The average grades of titanium and phosphorus are all around 2%, and the grade of phosphate concentrate can reach 33%. Above, the grade of titanium concentrate is over 46%. In addition, the project also studied the impact of tailings on the geological environment and the use of tailings, and proposed the use of the project.

Chengde super-depleted vanadium-titanium magnetite is a sub-mineral of the famous Damiao-type vanadium-titanium magnetite in China, and it is also a new mineral that has been successfully developed and utilized in Hebei Province in recent years.

The pulverizer is a machine that crushes large solid raw materials to the required size.

According to the size of the crushed material or crushed material, the pulverizer can be divided into coarse pulverizer, pulverizer and ultra-fine pulverizer.
There are four kinds of external forces applied to the solid during the crushing process: shearing, impact, rolling and grinding. Shearing is mainly used in coarse crushing (crushing) and crushing operations, and is applicable to crushing or crushing operations of materials with toughness or fiber and bulk materials; Impact is mainly used in crushing operation, suitable for crushing brittle materials; Rolling is mainly used in high fineness grinding (ultra-fine grinding) operation, which is suitable for ultra-fine grinding of most materials; Grinding is mainly used for ultra-fine grinding or ultra-large grinding equipment, which is suitable for further grinding after grinding operation.
The actual crushing process often involves several external forces acting at the same time, but high-end pulverizers are tailored according to the crushing environment.
