Research and Development of domestic and foreign titanium magnetic iron ore reviewed in this paper, detailing the findings of titanium magnetite Panxi. Aiming at the difference of coarse and fine grain magnetic properties of titanium magnetite, a magnetic separation process of coarse and fine grain size is proposed. This process innovatively solves the problem of low grade of iron ore concentrate in the mining ore confinement, making the iron concentrate grade break through 54%. The recovery rate is 74%. At the same time, combined with the difference of magnetic separation behavior of different grain sizes, a single ore model and flux linkage model are established, and the magnetic chain model is used to explain the influence of magnetic agglomeration on the magnetic separation concentrate. For the first time, a new process and a new theory for magnetic separation of titanium magnetite coarse and fine fractions were proposed and demonstrated. The main contents of the research and the main conclusions drawn are as follows: First, a systematic study on the magnetic separation behavior of titanium magnetite (1) The study of narrow-scale magnetic separation behavior was completed. The results show that the range of -0.10+0.045mm is the magnetic separation and easy selection, while the +0.25mm coarse and -0.045mm fine fractions are difficult to select, and the corresponding narrower grades are the best indicators. The sorting conditions are very different. If the whole-grain grade is selected, it is difficult to meet the sorting requirements of different grain sizes with the same magnetic separation condition, and it is impossible to achieve the best magnetic separation index; in addition, with the increase of the magnetic field strength The -0.045mm particle size magnetic separation concentrate grade and recovery rate are simultaneously improved, which is one of the important findings in this experimental study. (2) The study of full-scale magnetic separation behavior was completed. The results show that the fineness of grinding is the key factor that restricts the whole-scale magnetic separation index. Increasing the fineness of grinding can make the concentrate grade of full-scale magnetic separation exceed 55%, and the recovery rate is 72.21%, and the magnetic separation is changed. The magnetic field strength and drum speed have a certain effect on the improvement of concentrate grade, but they can not make the concentrate grade break through 54%. Therefore, improving the fineness of grinding is the fundamental way to improve the index of full-scale magnetic separation concentrate. (3) The study on the difference of coarse and fine grain magnetic separation behavior was completed. The results show that the magnetic field strength is the key factor affecting the fine-grained concentrate. The residence time, shear dispersion and drum speed also have a certain effect on the fine grade concentrate grade, while the grinding fineness is the influence of coarse grain. The key to the grade concentrate index. The best concentrate index is: -0.074mm size: grade 55.10%, recovery rate 71.40%, -0.045mm size: grade 54.47%, recovery rate 72.21%, +0.074mm size: grade 52.63%, recovery rate 75.63 %, +0.045mm size: grade 53.96%, recovery rate 74.88%, if the two coarse fractions of +0.074mm or +0.045mm are reground to -0.15mm, the concentrate grade can exceed 55%, recycling The rate can also reach more than 75%. (4) Through the study of the full-scale magnetic separation behavior and the coarse-grained magnetic separation behavior, it can be obtained that if the coarse-grained grade (±0.045mm) is used for magnetic separation, the fine-grained grade can be obtained by using the improved magnetic separator. The preferred concentrate index is 54.12% and the recovery rate is 74.06%. If the coarse fraction is re-ground to -0.15mm, an iron concentrate with a grade of 55.25% and a recovery of 75.40% can be obtained. Therefore, whether it is re-grinding or not, the fine and fine fractions can be magnetically selected to obtain the best concentrate index. Second, the establishment of titanium magnetite flux linkage model and its application in theoretical analysis (1) Establishing a motion model of a single titanomagnetite ore in a magnetic field. Through the analysis of the force and motion of a single titanomagnetite ore in the magnetic field of the φ1050mm×3000mm magnetic separator currently used in the climbing plant, the magnetic field characteristics required for the magnetic separation of different sizes of titanomagnetite are calculated in detail. The maximum sorting gap of the magnetic separator shows that the magnetic separator used in the field is not suitable for the classification of titanomagnetite with a particle size of less than 0.12 mm. (2) Establishing and demonstrating a magnetic flux model based on magnetic dipoles. By analyzing and calculating the magnetic polarization field characteristics of a single titanomagnetite ore, and the magnetic interaction energy and force between adjacent ore particles in the slurry, it is concluded that the magnetic attraction between the titanium magnetite ore is much larger than that of the ore. The magnetic force, gravity and water resistance are the driving force behind the agglomeration of the ore. The mechanism analysis of flux linkage formation shows that the flux linkage is formed at the moment when the ore particles enter the magnetic field and is centered on the larger diameter of the ore. When the diameter difference of the ore particles is small, the magnetic agglomeration will be dominated by the flux linkage. Magnetic agglomeration will be mainly based on magnetic wrapping. Since the magnetic chain is more easily damaged by shearing force than the magnetic package, it is also more conducive to eliminating magnetic inclusions and improving the concentrate grade. The flux linkage model not only explains the magnetic agglomeration phenomenon generally existing in the magnetic separation process of ferromagnetic materials, but also provides a theoretical basis for solving the problem of low concentration of concentrates due to magnetic agglomeration and the development of new micro-scale magnetic separators. (3) The application of the flux linkage model in the theoretical recovery calculation of titanium magnetite. By calculating the relationship between the theoretical recovery of titanomagnetite and its particle size, it is concluded that the magnetic separator currently used in the Climbing Concentrator is only suitable for the sorting of granular titanous magnetite with a particle size greater than 0.045 mm. When the particle size is less than 0.045 mm, only A modified magnetic separator can be used, otherwise the ideal magnetic separation index cannot be obtained. This conclusion is fully proved in the study of fine-grained magnetic separation behavior. In a word, this paper proposes a new magnetic separation process - titanium magnetite coarse and fine fractional magnetic separation process, which not only solves the problem of low grade of iron ore concentrate in the mining ore selection plant, improves the recovery rate, and has It is beneficial to the recovery of other beneficial components in the ore. In addition, this paper firstly proposed and demonstrated the magnetic flux model based on magnetic dipole. This model not only explains the influence of magnetic agglomeration on the magnetic separation index. Moreover, it is demonstrated that the fine-grained titanomagnetite is more likely to form magnetic agglomeration than the coarse-grained grade, and the conclusion that the fine-grained grade is treated separately is obtained, that is, the coarse-grained grade is separately magnetically selected, and the theory is a titanium magnet. The magnetic separation process of the coarse and fine grain grades of the ore provides a basis.

Rod mill is widely used in mining and water resources and hydropower industry. It can satisfy the requirements of various kinds of ore, rock crushing and artificial sand production,the product granularity is homogeneous and have a less overgrinding material. In our company, the high efficiency energy saving rod mill use rolling bearing support is substituted for the plain bearing bush,and the grease with dry grease instead of thin oil lubrication station,the energy saving 10% ~ 20%. Under the same power condition, the production capacity increased by 10% to 20%. Due to the poor material liquidity produced by dry method,the production capacity is only 40% ~ 70% of wet production.
