DINGS FLUX CONTROL CIRCUIT is a
TANK DESIGN
Tanks are constructed for one or more drums as
required and are of three general types as follows:
a)
breakthrough in the design of magnetic wet
drums.
Now, it is possible for the first time to eliminate
wasted magnetism, and at the same time
increase magnetic power. This invention puts
more magnetism and all the magnetism into
the working area outside the drum shell.
or
Concurrent Tank (see Figure 1-2).
(1) Most universally used tank.
(2) Used for cobbing, roughing, finishing and
heavy media.
(3) Longer time in the magnetic field for
higher recovery of magnetic materials.
(4) Spigot tank allows for rejection of coarse
non- magnetic solids.
(5) Long concentrating zone offers high
magnetic concentrate cleaning capability.
Sketches shown below illustrate the differences
between the flux control circuit, which is in all
Dings Wet Drums, and the other most widely
used magnetic circuits.
Figure 1-3. Counter-rotation Tank
The sandwich circuit has flux leakage on the
back or non-working surface of the assembly.
The salient pole circuit has considerable
leakage of the flux between the stacks of
magnets (between the poles). The flux
control circuit has no leakage.
Increasing the amount of magnet material in
either the sandwich or salient pole circuit, in
an effort to achieve more working magnetism,
has a severe limitation. The amount of wasted
flux increases, too. Increasing the amount of
magnet material in the flux control circuit
develops more working magnetism and no
waste. Result - lower equipment investment
and a higher magnetite recovery.
Both the sandwich circuit (upper) and the salient
pole design (middle) leak magnetic flux. The Dings
flux control circuit (bottom) controls flux leakage by
the addition of small magnets between the main
poles.
MAGNET MATERIAL
Wet Drum magnetic separators are finished with
permanent ceramic type magnets.

b)
Counter-rotation Tank (see Figure 1-3).
(1) Used on fine grind cobbing and roughing
applications (80% minus 325 mesh)
where high percentage of non-magnetic is
to be discharged, and as a secondary
heavy media separator.
(2) Magnetic concentrates picked up and
immediately discharged.
(3) Spigots for removal of coarse nonmagnetic tailings.
(4) High recoveries are obtainable with long
tailing and overflow launders.
c)
Counterflow Tank (see Figure 1-4).
(1) Used on finishing where quantity of nonmagnetics is at a minimum and ultimate
cleaning of magnetic concentrate is
desired.
(2) Undershot feed, with counterflow wash
water added under the discharge lip,
washes the concentrate and removes
entrained magnetics.
(3) All non-magnetics are removed by
overflow.
(4) Baffles and weirs allow for maximum
squeezing and wash of concentrate for
highest grade.
Grade VIII ceramic magnets are used.
There are 5 pole ceramic magnets of opposite
and alternating polarity in standard design.
Ceramic stacks are assembled to backplate
and charged with high energy charging
apparatus.
DRIVE ASSEMBLY
The drive assembly includes a short length shaft
extension drive by a standard motor, standard gear
reducer and standard V-belts and sheaves.
