Magnetic separator is one of the most widely used and versatile machines in the industry. It is suitable for the separation of magnetic substances with different magnetic properties. It is widely used in resource recovery, mining, timber, kiln, chemistry, food and other industries. For mining industry, the magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, hematite limonite and other materials with particle size less than 2-3mm. It is also used for iron removal of coal, non-metallic ore, building materials and other materials.
There are many classification methods for magnetic separators, details as follows
Type of magnet: Permanent magnetic separator , electromagnetic iron separator
Drying and wetting of ore: Dry magnetic separator, wet magnetic separator
Magnetic system: Drum magnetic separator, roller magnetic separator, drum roller magnetic separator, flat plate magnetic separator.
Classification of magnetic system: Open magnetic separator, closed magnetic separator
Number of magnetic system: Single drum magnetic separator, double drum magnetic separator, combined multi drum magnetic separator.
Classification of feeding mode: Upper feeding magnetic separator, lower feeding magnetic separator.
Classification of magnetic field intensity: Low intensity magnetic separator, medium intensity magnetic separator, high intensity magnetic separator.
Different structure of the tank: downstream, countercurrent and semi countercurrent.
The particle sizes of three different types of magnetic separators are as follows:
downstream tank ≤ 6 mm, countercurrent tank ≤ 1.5 mm and semi countercurrent tank ≤ 0.5 mm.
The downstream magnetic separator has large processing capacity. It is suitable for roughing and cleaning of strong magnetic materials with coarser particle size. It can also work in series. When the feed volume of the downstream magnetic separator is large, the magnetic particles are easy to lose in the tailings, so the operation management should be strengthened to control the lower pulp level.
Countercurrent magnetic separator is suitable for roughing and scavenging of fine strong magnetic minerals with high recovery but low concentrate grade. Because the coarse-grained materials are easy to deposit and block the separation space, the counter current magnetic separator is not suitable for processing coarse-grained materials.
Semi countercurrent magnetic separator can obtain high quality iron concentrate and good recovery, so semi countercurrent magnetic separator is widely used in production practice. It is suitable for the roughing and cleaning of ore particles less than 0.5mm. It can also be used in series or parallel to realize multiple sweeping and cleaning.
Our Magnetic Separators
We have a lot of magnetic separation equipments. Mainly introduce 3 types: wet drum magnetic separators, high intensity magnetic separators and 3 PCS disk dry magnetic separators.
Wet Drum Magnetic Separators :Wet drum magnetic separator is a kind of magnetic separator commonly used in iron ore concentrator. It is suitable for separating strong magnetic minerals.
High Intensity Magnetic Separators: High intensity magnetic separator is a kind of high intensity magnetic separation equipment for separating weak magnetic minerals. It is also called super strong magnetic separator. It can be divided into dry and wet separator. It is a general term for magnetic separators with magnetic field of 10000-16000gs or more.
3 PCS Disk Dry Magnetic Separators: The three disc dry magnetic separator is suitable for separation of mixed ores of various magnetic minerals. It is mainly used for dry selection of titanium, rare earth, tungsten tin, chromite, niobium tantalum, limonite, zircon, rutile, solitary residence and so on.
Magnetic separator is mainly used to select wet weak magnetic field and remove the strongly magnetic minerals of fine grains. They are widely used in mineral processing industry, coal washing industry, chemical industry, etc, e.g. recycle heavy formulas such as magnetic heavy media during heavy media separation, concentrate low-concentration slurry in iron ore and gather magnetic steel minerals, treat ore feeding from high-intensity magnetic separators, remove magnetic or weakly magnetic ores and coenobium, as well as prevent blockage of magnetic media.
Magnetic separator can be divided into two kind : roller magnetic separator and cylinder magnetic separator.
cylinder type magnetic separator whose diameter is less than 500mm, the magnetic intensity can made from 800 gauss to 9500 gauss.
cylinder type magnetic separator whose diametere is from 500mm to 1200mm,the max magnetic intensity is 5000 gauss.
the diameter size of roller type can made from 100mm to 600mmm.
the max Magnetic strength available is : 16000 gauss
the diameter size of roller type separator is : 100-140-160-180-220-240-300-320-380
the magnetic strenth of roller type is among 8000 gauss and 16000 gauss
The diameter and length of the magnet roller are customer-made.
In fact, the use of the effect is generally more than 150 will be better
The larger the magnet, the higher the throughput
The longer the length, the greater the handling capacity, this is customized according to customer requirements.
The thickness of our magnetic block is 25mm, is a circular disk
Disk and disk have gaps
About 3-4mm gap
6 question to ask before selecting model for customer
1. what is the mineral to process ?
2. adopt wet type separating or dry type ?
3. the feeding size of the mineral ?
4. what is the grade of the raw ore and how much grade required after processing ?
5. what is the gauss (magnetic intensity ) required for the magnetic separator ?
6. what is processing capacity ?
