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.

This type of flotation machine is flotation machine for relatively coarse particles and suitable for grading of non-ferrous metals, ferrous metals, precious metals and non-metallic minerals in SMEs. The particle size of 0.074mm accounts for 45%~98% in its handled material particles sizes, and it handles ore pulp with the concentration <45%. Its features are: absorbing air naturally with the volume up to 1.2 m3/(m2.min); absorbing ore pulp naturally and able to absorb feeding and foam middlings from the outside of the machine; horizontal deployment for operations of flotation machine available; godd ore pulp circulation in the cell, steady liquid level, without rotation of ore pulp or flower-like phenomenon in the cell; high separation efficiency and improving the recovery percentage of coarse and fine minerals; low power consumption, saving 15%~20% power consumption compared with flotation machines of the same kind with the same specifications and able to absorb adequate air and ore pulp at the meantime; long service life of quick-wear parts, especially the service life of the impeller and stator which is over 1 time longer than that of flotation machines of the same kind.

GF flotation machine can also be deployed together with JJF flotation machine. Deployed horizontally, GF flotation machine serves as the suction cell for job steps of roughing, scavenging and concentration while JJF flotation machine serves as the green cell. There is no need for foam pump for returning of middlings.
