Kyf-50 Flotation Machine In The Test Of 6000t / D Concentrator Applications

Since flotation has been used firstly in Montana in 1911, the data in the Mineral Processing Handbook, the latest product summaries of machinery companies and other information indicate that the cubage of flotation machine become larger and larger as the flotation is applied widely. The cubage of the earliest flotation machine is no more than 1 m~3, for example, the earliest 4A flotation machine is just 0.72m3. The cubage of flotation machine has made amazing change from the 80s particularly during the last decade, the cubage of a single flotation machine is up to 200m3 taking the OK-200 flotation machine produced by for example. And the cubage of column flotation is up to 300m3. Our country has always researched the domestically produced flotation machines according to the international researching from the 60s to now. In 2000, the biggest flotation machine whose cubage is up to 39m applied in De Xing copper mine. The most flotation machines which we arranged in our factories to deal with the middling granularity were general micromidi flotation machines. We also have big gap in applying large-scale flotation machines to productivity comparing with some other countries.Until the end of 2000, Beijing General Research Institute of Mining and Metallurgy and Jin Chuan Group Company have applied the KYF-50 flotation machine to the 6000t/d mineral processing project after the successful industrial test in the concentrating mill. This project has got more favourable mining index and economized more energy. Its effects and benefits are obvious on economy and society. This flotation machine can control the driving in air and the ore pulp's level precisely and automatically. It has the particular groove's structure with eight angles which looks like a "u" so as to economize productive material. The creative design of the primary axletree and the air distributing implement and the particular structure of nonmetallic stator or impeller guarantee the stability, economizing energy and rational ore pulp flowing. They make this flotation machinerun stably> have steady bubble level ^ have steady ore pulp flow > have well-proportioned ore grain in the groove and have deeper bubble layer in order to enhance product's grade and decrease the content of magnesia. It has not rigorous demands in the granularity gradation ^ flotation concentration ? medicament systerru flotation time and so on. It is easier to run fully loaded and less likely to spout ore out. It solves the prominent problem in most concentrating mills. The KYF-50 flotation machine is produced with scientific principle and its kinetic capability and technical capability are as well as the international big flotation machines.The appliance of the KYF-50 flotation machine in concentrating mills of our country indicate that this machine can increase the nickel's grade of the product by 2^ the nickel's recovery of the product by 0.1%;decrease the content of magnesia in the product by 4.1% and decrease the productive cost by 25%.
