Compared with reverse flotation, this way has simpler ore separating line, reliable craftsmanship, lower cost, shorter time limit and easier operation.
Through comparative analysis of the velocity field, pressure field and steam and liquid two-phase volume containing rate, it helps to master the distribution of the internal flow of flotation machine have made three different flotation cell structure of self-suction centrifugal floatation separator, namely double into feed tube and next cylinder cone angle 90°, single row into feed tube and next cylinder cone angle 90°and single row into feed tube and next cylinder cone angle120°.
Single-phase turbulent numerical simulation is for these three structures to get the distribution of pressure and velocity.
Results show that: when the structure is single row into feed tube and next cylinder cone angle 120°, flotation cell internal pressure and velocity of nearly wall area are biggest, this makes for flotation.
After the steam and liquid two-phase numerical
simulation calculating for these three structure, it gets the identical
instantaneous distribution of pressure and velocity and volume holdup
distribution of internal steam and liquid phases of flotation cell.
Results show that: when the structure is single row into feed tube and next cylinder cone angle 120°, it saves operating space, but the flow develops slowly under the same computing time.
When the structure is Single row into feed tube and Next cylinder cone angle 90°, the pressure and velocity of internal steam and liquid phases of flotation tank are biggest and flow develops quickly under the same computing time.
It is more conducive to flotation.
Domestic magnetic separation process based on high-frequency vibration mesh sieve, BX magnetic separator, magnetic separation column and disc filters has accurate entry point, few openings, which is reasonable and economical, and the more important thing is the aim of reducing silicon has also been achieved.
The application results show that the concentrate iron grade can be increased to about 69.5%, SiO2 content in the concentrate is reduced to less than 4%, the tailing grade and metal recovery keep essentially the same, and the additional processing costs is less than 20 yuan / t. http://jawcrusherhongxing.blog.com/
