Introduction
Flotation machine is applicable to grading of non-ferrous and ferrous metal, also applicable to grading of nonmetals, such as coal, fluorite and talc. The impeller of flotation machine is driven by motor v-belt, centrifugal effect is thus produced and negative pressure is formed, which, on the one hand, absorbs adequate air to mix with ore pulp, and on the other hand, stirs the ore pulp and mixes the ore pulp with medicines and refine bubbles; thus, the minerals will be adhered to the bubbles and float to the pulp surface and form foam layer. Adjust the opening of flash board and cone valve and control the liquid level to make the useful bubbles scraped out by scraper blade. For selection of flotation machines, the following information shall be indicated: Models, specifications and number of flotation cells. Number of scraper blade devices (left or right). Single-side scraping or double-side scraping. Numbers of feed boxes, middling boxes, tailing boxes, feed pipes and middling pipes. Liquid level can be controlled manually, electrically or automatically. Deployment diagram of flotation technological process should be provided.
Features
BS-K flotation machine is the pneumatic mechanical agitating flotation machine designed by China Institute for Non-ferrous Metals through absorbing the advantages of foreign advanced flotation machines. It shares the same appearance with XCF/KYF flotation machine, but with the following structural features: the spindle hangs on the side of rack; the bearing body is with light structure and easy to be installed, with good perpendicularity; the section of impeller is in cone shape while the stator is in radial pattern; it is with low wear, long service life and strong agitating strength. “U”-shaped cell reduces the ore settlement at the bottom of the cell; the spindle is with light structure and the stator is easily installed onto the bottom of cell. The installed power is low, saving 50% energy compared with A-type flotation machine; bubbles are dispersed homogeneously, air dispersion is fine, the foam is stable, the suspension of ore particles are good, and the recovery percentage is high.
This product is divided into several units: single-cell, double-cell, three-cell, four-cell, five-cell and six-cell, etc. It does not possess the capability of absorbing ore pulp and air naturally, the flow of ore pulp should be arranged step-wise, and the returning of middlings counts on the foam pump.
