The flotation machine was successfully developed by the North Mining Institute in 1989 and produced by Jiangsu Baolong Electromechanical Manufacturing Co., Ltd. (Jiangsu Baolong, former Xiangyang Mining Machinery Factory). Its structure is shown in Figure 1.
The CLF-4 coarse-grain flotation machine has two types of DC tank and suction tank. The main difference is the impeller structure (Fig. 2). The DC tank adopts a single blade impeller, which cooperates with the tank body to generate a large circulation of the slurry in the tank, and the effect of dispersing air is good. The suction groove adopts a bidirectional blade impeller, which is an upper blade which increases the suction effect on the basis of the DC groove impeller. The blades of both impellers are inclined backward by a certain angle, but the lower blade height of the suction impeller is smaller than that of the direct current type. Practice has proved that the impeller stirring force of this structure is weak, and the slurry circulation is large, the power consumption is low, and the combination of the tank body and the grid plate fully ensures the suspension and air dispersion of the coarse-grained mineral.
The characteristics of the CLF-4 coarse-grain flotation machine are as follows: 1 The new impeller certain subsystem and the new slurry circulation mode are adopted. At the lower impeller peripheral speed, the coarse-grained mineral can be suspended in the middle part of the trough, and the return impeller The circulating pulp concentration is low and the ore particle size is fine, which is not only beneficial for coarse flotation, but also for fine flotation; 2 rising pulp is produced in the tank, which helps the mineralized bubbles attached with coarse minerals to float and reduce The separation force between coarse minerals and bubbles; 3 impeller peripheral speed is low, the circulating impeller concentration of the return impeller is low, the granularity is fine, so the impeller and stator wear are greatly reduced, the power consumption is low; 4 the gap between the impeller and the stator is large, With the wear of the impeller and stator, the aeration and air dispersion changes little, which can ensure the stability of the selection index; 5 grid plate causes the coarse particle suspension layer, and can reduce the turbulent flow in the upper part of the trough, which is conducive to coarse floating Option 6; using additional inflation method, large amount of inflation, uniform bubble dispersion, stable mineral surface, is conducive to coarse particles floating; 7 designed a suction tank, so that the flotation machine can be placed at the same level without bubbles
1. Jiangsu Baolong The technical performance of the CLF-4 coarse-grain flotation machine produced by the company is listed in Table 1. The external dimensions and configuration are shown in Figure 3 and Table 2.
2. North Mine Institute North Mine Institute has further developed CLF type coarse particle flotation machine in recent years. It has four types of specifications to form a series. Its characteristics are: 1 treatment of the largest mineral particle size up to lmm; 2 slots are provided with grid plates, so that The surface of the slurry is stable and the technical performance is improved; 3 the air is well dispersed, the aeration is large, and the power consumption is low; 4 the slurry is well cycled, and the coarse-grained material is not sinking when it is treated; 5 the automatic liquid level control system is provided, and the operation and management are easy; 6 The coarse particle flotation machine is equipped with a suction tank, which can be horizontally arranged in the flotation operation, eliminating the foam pump used for the return of the middle mine. The technical performance is shown in Table 3, and the mounting dimensions are shown in Figure 4 and Table 4.
