1) The self-grinding machine can open its doors and fully utilize its production capacity.
2) Crush the hard-to-grind particles with a fine crusher to avoid the use of high-quality steel balls and liners required for semi-self-grinding.
3) After the finely crushed product is stored in the mine bin, it can enter the ball mill , and the ball mill can be adjusted to make the whole system production capacity stable.
4) The largest domestic ф7500×2800mm self-grinding machine and ф3600×6000mm ball mill were selected. 350/300mm (14/12in) Walman pump was introduced and equipped with hydraulic coupling for speed regulation and 660mm (26in) Crewe. The Boer hydrocyclone is used as a grading equipment for grinding, and the JJF-16 flotation machine is used for roughing and sweeping. The effect is good, especially the 16m3 flotation machine is more prominent.
Since the self-grinding product has a good dissociation degree of useful minerals and the classification efficiency of the cyclone is high, the selection index is higher than the conventional grinding and floating index, as shown in the following table. 
1) Large geological reserves, low grade of ore, but good ore selectivity, suitable for the construction of large-scale concentrating plants.
2) From the process flow to equipment selection, it is the most comprehensive and representative plant in China. There are three stages in the crushing process (the crushing station that does not include the stope). A closed-circuit and wash-washing with single-stage ball milling process; there are three sections and one closed-circuit non-washing and single-stage ball milling process; there is “self-grinding-ball milling-fine crushing†Grinding the new process. In the equipment selection, the crushing equipment includes domestic rotary crusher , jaw crusher, standard and short-head cone crusher, and introduced hydraulic cone crusher; grinding machine has ф1500×3000mm, ф2100×3000mm, ф3200×4500mm, Ф3600×6000mm and the second selection plant are imported from abroad with various specifications such as ф5.03×6.4m; the self-grinding machine has the first domestic ф7500×2800mm self-grinding machine; the grading equipment has high-grade and sunken spirals. There are also domestic and imported hydrocyclones outside the classifier. In addition to the XJK-2.8 flotation machine, there are CHF-X14 inflatable mechanical agitation flotation machine and JJF-4 and JJF-16 mechanical agitation. Flotation machine and so on.
3) Dexing Copper Mine has been built in the early 1960s and has been in production since 1965. It has been built for several times. This in batches, from small to large construction methods, not only conducive to the construction of the mine, but also for the use of funds, and economic recovery is more reasonable, is a good way to mine construction.
The main equipment of a selection plant is shown in the following table:
