China's largest single-slot flotation machine---KYF-160 inflatable mechanical agitating flotation machine was successfully developed by Beijing Research Institute of Mining and Metallurgy and passed the expert appraisal organized by China Nonferrous Metals Industry Association. This is the first large-scale flotation machine developed by the Beijing Research Institute of Mining and Metallurgy in 2000. After the development of the first large-scale flotation machine with independent intellectual property rights in China---KYF-50 type aerated mechanical agitation flotation machine, China is in the field of large-scale flotation equipment. Another major technological breakthrough in the field.
The successful development of KYF-160 inflatable mechanical agitation flotation machine has filled the gap in the research, design, manufacture and application of super large flotation machine in China, further shortening the gap between China's large flotation equipment and international advanced level. The distance provides a strong equipment guarantee for improving the equipment level of China's mine concentrators and promoting the modernization and large-scale construction of China's mines.
The equipment can be widely used in the selection of non-ferrous metals, ferrous metals and non-metallic minerals, and has a broad market prospect.
The flotation machine is one of the most important sorting equipment in the field of mineral processing. With the rapid development of the global economy and the rapid development of science and technology, the requirements for the quality and quantity of mineral raw materials provided by the mineral processing industry are constantly increasing.
In the face of the current situation and future trends of mineral resources and the complexity of mineral resources, mineral processing enterprises have adopted a way to increase the scale of their concentrating plants in order to obtain better economic benefits. At present, the daily processing capacity of many new concentrators is generally more than 10,000 tons. The use of large-scale flotation equipment in large-scale concentrating plants has the advantages of small installation equipment, small floor space, easy automatic control, low capital investment, small installation capacity, and high comprehensive economic benefits. The flotation machine is large. It has become an international trend.
Internationally, large-scale plants generally use a flotation machine with a single tank volume of about 100m3. However, China generally has a gap of about 20m3, which is compared with the international advanced level. It cannot meet the needs of modernization and large-scale construction of mines in China, which has caused the monopoly of large-scale flotation equipment in China's concentrators to be monopolized by foreign manufacturers. In order to complete the renovation and expansion project, the domestic concentrator has to accept the high price of equipment from foreign manufacturers, resulting in a substantial increase in infrastructure investment costs, which greatly affected the economic benefits of the company. The development of large-scale high-efficiency flotation equipment with independent intellectual property rights is an urgent need of China's mineral processing industry.
The BGRIMM series of flotation machines developed by the Beijing Research Institute of Mining and Metallurgy are used in 75% to 80% of large and medium-sized mines in China. KYF-160 Inflatable Mechanical Stirring Flotation Machine has a single tank volume of 160m3 and adopts a unique impeller-stator structure. It has a large circulation of pulp, low indenter, sufficient slurry suspension, uniform distribution of ore particles, and stable radial flow. , high recovery of coarse and fine minerals. The innovative double foam tank and double push bubble cone structure enable the flotation foam to be discharged smoothly in time. The self-control technology can maintain the slurry level at the set value.
Industrial tests show that: KYF-160 inflatable mechanical agitation flotation machine has obvious effect on improving the recovery rate of concentrate grade and useful components and improving the marking operation index, and has excellent sorting performance, which can greatly reduce the unit energy of mineral processing operations. Consumption, overall machine performance and comprehensive technical and economic indicators have reached the international advanced level.
