Magnetic separator is one of the most universal machine for construction
industry, which is used for deironing in powder. Magnetic separator is widely
used for resources recycling in wooden materials, mining industry, kiln,
chemistry and food, etc. It applied to dry or wet magnetic separation with
materials particle size under 3mm, such as magnetic iron ore, Magnetic pyrite
mine, baking and titanium iron, coal, nonmetal ore and construction materials.
In most cases, the magnetic system of magnetic separator made from the
composition of High quality ferrite materials and magnets, the average magnetic
induction of which is 800-4000mT. Since the technological development, now the
magnetic sepatator can be made into rollor shape up to 8000mT, which is the
highest magnetic induction at present.
Sorts of magnetic separators:
There
are a variety of magnetic separators, in a whole, that can be sorted into disk
dry magnetic separator, flat ring magnetic separator, SHP and vertical wet magnetic sepatator.
Disk dry magnetic
sepatator
This type machine is the main ore dressing equipment which is most
commonly used for iron ore separation and manganese ore sepatation. Dry magnetic
separator can be sorted into one tubular three rollers dry machine, two tubulars
two rollers MS and tubular roller MS. DD is widely used in fine reselection of
weak magnetic ore and of rare metal ore under 2-3mm particle size. It has three
types, single disk(diameter is 900mm), double disks(φ=576mm) and triangle disks
(φ=600mm). The magnetic induction can reached 880-1440 thousand Ann/m. Among
them, the double-disk type is more widely used. The main body of magnetic
separator is composed of electronic magnetic iron and rotatable pendulum
induction disk, the two of which presents "W" shape. The disk turns upside down
as a gear disk, whose diameter is half the width of . The disk drives by worm gear and worm reduction drive. We can
adjust the polar distances between disc and the electromagnets (the adjusting
range 0-20 mm) through handwheel. For fear of blocking, we installed a weak
magnetic polar in tubular ore feeder to discharge the strong magnetic ore in
advance.
When foreign materials went into crushing cavity or machine
overload,
will start spring insurance system for safety. The mine discharging mouth will
be larger, the foreign matter discharges from the crushing chamber. We can use
clear chamber system if foreign materials stucked and let the foreigners out the
crushing chamber. And then, under the action of the spring, mine discharging
mouth automatically reset and the machine back to normal.
