BS-K type flotation machine overview
Model BS-K flotation machine is a highly efficient and energy-saving inflatable mechanical agitation flotation equipment. It combines the advantages of external forced inflation and mechanical agitation, and through the innovative side-mounted spindle design and "U" shaped tank structure, it significantly improves the stability of the equipment operation and separation efficiency. This equipment is designed to meet the high requirements for fine separation of concentrate grade and recovery, and its recovery can be increased by more than 2% compared with the conventional equipment, which is an ideal choice for the production of high-quality concentrates.
BS-K type flotation machine working principle
The working process of BS-K flotation machine is a precise combination of mechanical force and aerodynamics:
-
Synergistic inflation and mixing: the external blower provides a stable and adjustable air source, while the conical impeller rotates at high speed to generate strong turbulence, realizing the forced mixing and uniform dispersion of air and slurry.
-
Mineral Separation: Under the strong turbulence environment, the hydrophobic minerals fully collide and attach with the fine, uniform air bubbles generated by the radial stator cutting to form mineralized air bubbles.
-
Mineral slurry flow: adopting step configuration, utilizing the self-weight of mineral slurry to form self-flow, passing through each flotation tank in turn.
-
Foam collection and stabilization: the mineralized bubbles float to form a stable foam layer, which is scraped out by the scraper. Part of the mineralized foam in the concentrating zone can be returned to the previous tank for re-election through the foam pump to improve the recovery rate." The "U" shaped tank structure helps to form a stable separation environment.
Core Advantages and Features of BS-K Flotation Machine
| Structural Advantages |
Performance Advantages |
| ✅ Side-hanging spindle design: the transmission mechanism is hung sideways, good verticality, smooth operation and sufficient space for maintenance. |
✅ Extremely high recovery rate: optimized aerating and mixing system increases the recovery rate of useful minerals by more than 2%. |
| ✅ "U"-shaped tank structure: effectively prevent the accumulation of ore at the bottom of the tank, ensure that the ore particles are fully suspended, avoid dead zones and reduce metal loss. |
✅ Good separation effect: the bubbles are dispersed uniformly and finely, and the mineralization efficiency is high, which is conducive to obtaining high-grade concentrate. |
| ✅ Modular and adjustable design: provide single to six tanks with various configurations, adjustable transmission parts , convenient maintenance and repair. |
✅ Stable operation and low energy consumption: designed for high efficiency operation, it ensures strong performance while controlling energy consumption. |
| ✅ Highly efficient impeller-stator system: the combination of conical impeller and radial stator provides strong mixing force and greatly reduces wear and tear, resulting in a long service life. |
✅ Strong adaptability: especially suitable for fine sorting and difficult to sort ores, insensitive to fluctuations in feed volume and concentration. |
