function.Production capacity:96~560t/h.Product
Improvement:1、Baseboard of feeding tank adopts Blind plate +
screen” to pre-screen the small block materials.2、Double eccentric
shaft vibrator.
Product Application:
- To be applied to the dry preconcentration of high-grade and lean
magnetite ore before grinding with the selected granularity below
30mm. The finer the granularity is, the better the result is.
Generally, large amount of tailings can be discharged, and the
grinding quality can be greatly enhanced. To be applied to dry
separation and recycling of the lost magnetite from the abandoned
tailings. To be applied to dry separation and recycling of
ferromagnetic materials from the abandoned steel slag.
- As shown in the figure, the separation cylinder without belt
outside will enhance the intensity of magnetic field of the
separation area. The rotating magnetic system (wrap angle of 360
degree) is set inside the separation cylinder, while the fixed
magnetic system (magnetic wrapping angle of less than 90 degree) is
set inside the ore dumping cylinder. The rotation direction of the
separation cylinder is as the same as that of the ore dumping, but
is opposite to that of the rotating magnetic system.
- When the materials feeder transports the minerals to the separation
area of the separation cylinder, the magnetic minerals will
alternate rapidly and repeatedly within a short time through the N
pole and S pole of the magnetic field, and the magnetic minerals
will do magnetic reversal and magnetic agitation. The non-magnetic
(weak) magnetic mineral mingled in the magnetic minerals is not or
slightly affected by the adsorption of the magnetic force, moving
to the outer layer gradually, and is thrown out by the centrifugal
force, gravity and the joint action of magnetic turn and agitation
of magnetic minerals.
- In the separation area of the separation cylinder, the centrifugal
force and gravitation of magnetic minerals mingled with
non-magnetic minerals are much less than the magnetic force. With
the adsorption of the magnetic force and the joint action of the
magnetic turn and agitation of magnetic minerals, the magnetic
minerals will move to the inter layer gradually. When the magnetic
minerals rotate to the ore unloading area with the separation
cylinder, as the rotation magnetic system is eccentric, the
magnetic density of the ore unloading area for the separation
cylinder is extremely weak, and most of the magnetic minerals can
fall off automatically. A small quantity of magnetic minerals not
falling off will be adsorbed to the external surface of the ore
unloading cylinder with higher magnetic density when rotating to
the position nearby the ore unloading cylinder so as to realize the
automatic unloading of magnetic minerals.
Product Features:
- 1, This patented product is a kind of upgrading equipment based on
conventional magnetic roller or conventional dry separator. When it
is working, the magnetic minerals will take rapid magnetic reversal
and magnetic agitation, which will significantly reduce the number
of non-magnetic (weak magnetic) minerals in the magnetic minerals.
In this way, the efficient separation of magnetic minerals and
non-magnetic (weak magnetic) minerals will be realized, and fine
magnetic minerals and coarse magnetic minerals will not get lost.
- 2, This patented product solves the eddy current heating problem,
ore sticking problem for separation cylinder, and mine unloading
problem of conventional 360 degree rotating magnetic dry separator.
The conventional 360 degree rotating magnetic dry separator must
use the belt to unload the mine by the outside of it, therefore the
magnetic minerals are easy to enter the central space between the
inside belt and sorting tank. The magnetic minerals attached on the
surface of sorting tank cannot fall off automatically (cannot
unload mine automatically). As the accumulation grows, the
separation effect is affected. Whats worse, rapid wear of sorting
tank body as well as the belt will be caused, and the normal
operation of production will be seriously affected.
- 3, Under the condition that the grade of the dry tailings is equal
to or even lower than that of conventional magnetic roller or
conventional dry separator, for high-grade and lean magnetite with
different features, by adjusting corresponding technical parameters
and structure, about 10%-30% tailings discharging and about
1.0%-8.7% of concentration grade can be increased compared to
conventional magnetic roller or conventional dry separator. The
concentrate grade of dry separation is significantly enhanced
compared to the feeding grade. Under the conditions of fine
crushing size of below 2 mm and coarse dissemination size, more
than 60% grade of the dry separation concentrate can usually be
obtained directly. In the actual production, if one p
