The key to improving the production efficiency of mining enterprises is to resolutely implement technological transformation and equipment renewal. With the development of today's science and technology, it is no longer the era of improving production efficiency by the traditional method of mechanical overload operation. However, it increases the overdraft loss of the life of the mineral processing machinery, which reduces the production effect in the sense of overall production.

1. Renovation of mineral processing machinery and equipment

The 12m single-layer thickener in the existing mineral processing machinery and equipment is not equipped with a corresponding buffer gas tank, and the ore feeding station is not equipped with a wage barrel and a diffuser plate under the barrel, etc., which lead to the unstable operation of the thickener during work. These problems can be well solved by effective technical transformation and reasonable production equipment. The selection process in the beneficiation process must eliminate the outdated JJF-4 flotation machine, blow compressed air into the porous medium, and replace the pulp with an inflatable flotation machine that can be filled with air for stirring. This transformation method is beneficial to improve the beneficiation index, save the process cost, and facilitate the maintenance and management of the machine.

For the phenomenon that the conveyor belt sometimes meanders, the method of combining the conveyor belts of the crushing system with each other can be adopted; for the slippage phenomenon of the product conveyed by the conveyor, a long feed screw with an appropriate distance can be selected as the guide of the product conveying, and the The transfer speed was reduced from 1.25m/s to 1m/s, and finally the width of the conveyor belt was increased again from the existing condition to 800mm. Since the effect of the thick-walled seamless steel pipe is far more than that of the broken vibrating screen bone pipe, the thick-walled seamless steel pipe is used to eliminate the effect of the broken vibrating screen bone pipe, and the existing seven reinforcing rib plates are reduced to three. The shape of the separator changes into the shape of the groove, which can further increase the volume of the sorting and improve the working efficiency and working intensity of the entire sorting process.

2. Improve and optimize production technical conditions

The crushing cone crusher is not conducive to the improvement of production efficiency due to low production efficiency, high circulating ore volume, and most of the products produced do not meet production requirements, and must be equipped with more equipment and must cooperate with more complex equipment to complete the work. and improve. The data shows that the experiment proves that replacing the traditional cone crusher with the HP300 cone crusher can greatly improve the production efficiency of the machine and the qualified rate of the product. This new type of crusher reduces the particle size of the crushed products, increases the fine opening of the mill, and realizes the preliminary individual separation of iron minerals by more finely modifying the structure and size of the crushing chamber and reducing the diameter of the sieve hole.

In terms of flotation collector transformation, the combination of quinaxanthin and isoprene can effectively improve the hydrophobicity of iron minerals, which is beneficial to the separation of iron minerals. In addition, other aspects of transformation can also be carried out, such as using liquid sodium chloride instead of solid products, etc., to make the specific operation process more concise and convenient, and improve the reliability of production. In addition, liquid sodium chloride can reduce the amount of drugs added, save costs and improve economic benefits. In order to optimize the control of unloading products from the thickener, an automatic unloading device can also be installed on the single-layer thickener during production in the mining area.

3. Optimize the production process

Optimizing the specific production process of the beneficiation process can promote the improvement of the working efficiency of the overall beneficiation mechanical system. For example, the water obtained from the tailings in the mining area is technically recovered and put into the production process again as a raw material to realize the recycling of industrial water, which not only realizes zero pollution and zero discharge of industrial wastewater in terms of environmental protection, but also saves production costs and reduces Economic measures of production inputs.
