极品斗地主Magnet conductivity stainless steel bar medium box or stainless steel mesh magnet medium pile is installed with Rotary ring(4)。 During mineral selection, rotary ring(4)rotates clockwise, and ore slurry will be fed from feeding hopper(6),then flowing through the circle in rotary ring along gap of upper iron yoke(5),the magnetic medium is magnetized in magnetic field, forming high gradient magnetic field in surface, magnetic particles in ore slurry are attracted to the surface of magnetic medium, rotary ring(4)takes it to the top of nonmagnetic field area, and then washed into concentrate hopper by flushing water of concentrate flusher(12),nonmagnetic particles via inner annulus to outer annulus flow into tailings hopper(10) along gap of bottom iron yoke(2)and then discharged。

Main Features

* High gradient magnetic separator adopts vertical ring rotation, reverse flushing the ore. CHDL series separators adopt the vertical ring rotation type, for each group of magnetic medium, the direction of reverse flushing is opposite to the feeding direction, and the coarse particles can be flushed out by water without passing through the magnetic medium pile. Thereby it effectively avoids magnetic mediums blocking.

* Using ore slurry pulsing mechanism to drive ore slurry to generate pulsating hydro-force。 Under the action of pulsating hydro-force, the mineral granules in the slurry are always scattered, which improves the quality of magnetic concentrate。

* Horizontal ring magnetic separator has strict requirements to the feeding particle granularity. We designed the unique magnetic system structure &optimized combination of magnetic medium which raises the upper limit of mineral grain size up to 2.0mm, simplifies the mineral grading work and increased adaptability of separator.

* High magnetic field strength, the background magnetic field is up to 1。3T, the surface magnetic field of medium box is up to 2。6T。

* Due to the special design of the medium box, magnetic field can generate high gradient magnetic field within high density and disorderly bars medium structure.

According to attractive force formula of magnetic field to material F=K×X×B×ΔH×V, which illustrates high gradient magnetic field makes it easier to attract paramagnetic mine。

F:attractive force; K: coefficient; X: specific susceptibility; B: flux density; ΔH: gradient; V: materials’ volume.

* Outlet box is simple, beautiful and easy connection to the site interface.

* With automatic precaution function. When the cooling water pressure is insufficient or the cooling water outlet temperature is too high, the system will give sound and light to alarm, meanwhile it will automatic cut off power supply, thus service life is extended.

* Technical parameters, like magnetic field, ring rotating speed, pulse box stroke & pulse box frequency all are adjustable, thus it is easy for user to finalize the optimum technical parameters.

* The electrical control cabinet adopts air cooling, which is more reliable and safer.

Optional Equipment for Separator

KYTS Series Drum Screen

Application Range

极品斗地主Since the magnetic separator is a kind of separator which has requirements for materials’ particle sizes, ore slurry should be first separated by drum screen before entering the separator. Drum screen not only can be used as slag removal equipment for CHDL vertical ring magnetic separator, but also be used in metallurgy, mining, chemical abrasive and other industries which need slag removal equipment.

Technical Features:

①It rotates steady with low speed, featured high liability, low maintenance rate and long service life. It is not easy to block, especially it is suitable for separating damp materials
②The area of screen is big enough, it can touch materials alternately thus the service life has been prolonged.
③The screen features low noise, totally sealed structures and no dust contamination.
极品斗地主 ④The screen can be separated with different sizes thus it can be adapted to variable particle sizes products.

极品斗地主The drum screen will rotate under the force of driving mechanism, ore slurry from the lower left part can be poured to the drum screen circle, fine particle ores and water will fall to the ore bucket through screen, and then they will flow to the CHDL magnetic separator by fine particle pipes for separation. The coarse particles will be transmitted to top by slag carrying plate and coarse particles will be flushed into the recycling hopper at last.
