S\u00e9paration magn\u00e9tique<\/strong> is a fundamental mineral processing technique that separates materials based on their magnetic properties. The magnetic separator machine can effectively select a large number of magnetic minerals, such as magnetite, hematite, limonite, manganese siderite, wolframite, ilmenite, manganese ore, manganese carbonate, metallurgical manganese ore, iron ore, kaolin, manganese oxide ore, and rare earth ore. In this guide, we break down the various classification methods for \u00e9quipement de s\u00e9paration magn\u00e9tique<\/a>.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

1. Types of Magnetic Separators: By Material State<\/h2>

Dry-type Magnetic Separators and Wet-type Magnetic Separators<\/h3>\n\t
\n\t\t
\n\t\t\t

According to the state of the material, the magnetic separators are divided into dry-type magnetic separators<\/strong> et wet-type magnetic separators<\/strong>. The dry magnetic separator refers to the material keep dry, don’t need to be mixed with water in the magnetic separation process. The material for a wet magnetic separator must be mixed with water or other media.<\/p>\n

Structure<\/strong><\/p>\n

The dry magnetic separator generally does not need a tank for accommodating the slurry, and the material is conveyed by a vibrating feeding device; a dustproof device is often provided. The wet magnetic separator has a tank to accommodate the slurry to maintain the fluidity of the material, and the slurry is usually transported by a pompe \u00e0 boues<\/a>.<\/p>\n

Mineral Size<\/strong><\/p>\n

Dry magnetic separation functions for bulk, coarse particle separation, but also fine mineral separation, while wet magnetic separator can not sort large bulk minerals; most are effective for fine or even fine particles, except for a few models that can select coarse particles. HGMS (high gradient wet magnetic separator) can sort micron-sized materials using a suitable magnetically permeable medium.<\/p>\n

Water Requirements<\/strong><\/p>\n

Dry magnetic separation requires low water content, dry materials, good liquidity, do not adhesion agglomeration.
\nL'op\u00e9ration de s\u00e9paration magn\u00e9tique par voie humide est soumise \u00e0 certaines exigences en mati\u00e8re de concentration de la boue. Il n'y a pas de limite \u00e9vidente \u00e0 la concentration de la s\u00e9paration magn\u00e9tique grossi\u00e8re, mais la concentration du mat\u00e9riau ne doit pas \u00eatre trop faible pour contr\u00f4ler efficacement la force n\u00e9gative du fluide pendant l'op\u00e9ration de traitement des min\u00e9raux. Lors de la s\u00e9lection magn\u00e9tique des particules fines, la concentration doit \u00eatre \u00e9lev\u00e9e pour garantir la r\u00e9cup\u00e9ration des min\u00e9raux magn\u00e9tiques.<\/p>\n

Advantages and Application<\/strong><\/p>\n

Dry weak magnetic separators have features like a simple process, low investment, and low water consumption. However, the bottleneck of the dry cylinder magnetic separator is that the dust is difficult to control; as environmental protection requirements become stricter, the dry type magnetic separation is gradually replaced by the wet weak magnetic separator. At present, the fine-grained dry magnetic separation machine is only used in water-shortage areas and severe cold areas.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

2. Types of Magnetic Separators: By Magnetic Field Strength<\/h2>

Weak, Medium, Strong Magnetic Separators<\/h3>\n\t
\n\t\t
\n\t\t\t

According to the magnetic field strength, the magnetic separators are divided into three types: weak magnetic separator (low-intensity magnetic separator), medium magnetic separator, and strong magnetic separator (high-intensity magnetic separator).<\/strong>
\nLe s\u00e9parateur magn\u00e9tique faible va de quelques centaines \u00e0 3000 Gs ; le s\u00e9parateur magn\u00e9tique fort se r\u00e9f\u00e8re g\u00e9n\u00e9ralement \u00e0 3000Gs \u00e0 6000 Gs, et le s\u00e9parateur magn\u00e9tique \u00e0 champ magn\u00e9tique moyen se situe entre les deux.<\/p>\n

La raison pour laquelle il est class\u00e9 en fonction de l'intensit\u00e9 du champ magn\u00e9tique est li\u00e9e aux propri\u00e9t\u00e9s magn\u00e9tiques de divers min\u00e9raux courants (un autre article). Classification magn\u00e9tique des min\u00e9raux<\/a>). Cependant, il faut savoir qu'il n'existe pas de norme absolue pour les diff\u00e9rentes forces magn\u00e9tiques et les \u00e9quipements correspondants.<\/p>\n

Magnetic Field Strength<\/strong><\/p>\n

In the actual magnetic separation machine, the magnetic field strength ranges from hundreds of Gauss to 20,000 Gauss; some even exceed 20,000 Gauss, but it is rarely used in general beneficiation production. Excessive magnetic field strength will lead to weak magnetic minerals to agglomerate that is not conducive to beneficiation. So the upper limit of the magnetic field strength of the strong magnetic separator is 20000Gs.<\/p>\n

On the working surface of various magnetic separators, the magnetic field strength varies at different points and in different ranges, and the working magnetic field is a non-uniform magnetic field. Generally, the value of the magnetic field strength expressed refers to the maximum. magnetic strength; some factories may list the average value.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

3. Types of Magnetic Separators: By Magnetic Source<\/h2>

Permanent Magnet and Electromagnetic Magnetic Separators<\/h3>\n\t
\n\t\t
\n\t\t\t

According to the type of magnetic field, the magnetic separators are divided into permanent magnet magnetic separators<\/strong> et electromagnetic magnetic separators<\/strong>.
\nLe s\u00e9parateur magn\u00e9tique \u00e0 aimant permanent utilise un mat\u00e9riau \u00e0 aimant permanent tel que la ferrite ou le n\u00e9odyme fer bore pour g\u00e9n\u00e9rer un champ magn\u00e9tique de travail, et le s\u00e9parateur magn\u00e9tique \u00e9lectromagn\u00e9tique utilise un aimant avec une culasse, un sol\u00e9no\u00efde et un aimant pour g\u00e9n\u00e9rer un champ magn\u00e9tique.<\/p>\n

Magnetic Field Strength<\/strong><\/p>\n

L'intensit\u00e9 du champ magn\u00e9tique du s\u00e9parateur magn\u00e9tique \u00e0 aimant permanent est fixe, mais les diff\u00e9rentes zones d'action de la surface de travail de la s\u00e9paration magn\u00e9tique peuvent \u00eatre con\u00e7ues pour avoir des intensit\u00e9s de champ magn\u00e9tique diff\u00e9rentes. Le s\u00e9parateur magn\u00e9tique \u00e9lectromagn\u00e9tique peut ajuster l'ensemble du champ magn\u00e9tique, mais les valeurs de l'intensit\u00e9 du champ magn\u00e9tique dans la surface de travail constituent un champ magn\u00e9tique \u00e9quilibr\u00e9 et uniforme.<\/p>\n

Consommation \u00e9lectrique<\/strong><\/p>\n

L'\u00e9nergie magn\u00e9tique du s\u00e9parateur magn\u00e9tique \u00e0 aimant permanent est faible, alors que la s\u00e9paration \u00e9lectromagn\u00e9tique n\u00e9cessite une consommation d'\u00e9nergie \u00e9lev\u00e9e pour g\u00e9n\u00e9rer le courant d'excitation. La consommation d'\u00e9nergie par unit\u00e9 du s\u00e9parateur magn\u00e9tique permanent est beaucoup plus faible que celle du s\u00e9parateur magn\u00e9tique \u00e9lectromagn\u00e9tique.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

4. Types of Magnetic Separators: By Structural Design<\/h2>

Cylindrical\/Drum, Roller, Disc, Ring Magnetic Separators<\/h3>\n\t
\n\t\t
\n\t\t\t

According to the structure of the main working part of the magnetic separator, it is divided into cylindrical (drum) magnetic separator, roller magnetic separator, disc magnetic separator, ring magnetic separator<\/strong>, in addition, have rotor magnetic separator, belt magnetic separation, conical magnetic separator, but these types of magnetic separators have been used less.<\/p>\n

Cylindrical\/Drum magnetic separator:<\/strong> Most common for both dry\/wet separation
\nRoller magnetic separator:<\/strong> High-precision sorting for fine materials
\nDisc magnetic separator:<\/strong> Multi-stage separation capability
\nRing magnetic separator: <\/strong>Continuous processing of slurry materials<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
