Separa\u00e7\u00e3o magn\u00e9tica<\/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 equipamento de separa\u00e7\u00e3o magn\u00e9tica<\/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> e 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

Estrutura<\/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 bomba de polpa<\/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.
\nA opera\u00e7\u00e3o de separa\u00e7\u00e3o magn\u00e9tica h\u00famida tem certos requisitos sobre a concentra\u00e7\u00e3o da lama. N\u00e3o existe um limite \u00f3bvio para a concentra\u00e7\u00e3o da separa\u00e7\u00e3o magn\u00e9tica grosseira, mas a concentra\u00e7\u00e3o do material n\u00e3o deve ser demasiado baixa para controlar eficazmente a for\u00e7a negativa do fluido durante a opera\u00e7\u00e3o de processamento mineral. Ao selecionar magneticamente as part\u00edculas finas, a concentra\u00e7\u00e3o deve ser elevada para garantir a recupera\u00e7\u00e3o dos minerais magn\u00e9ticos.<\/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>
\nO separador magn\u00e9tico fraco \u00e9 de v\u00e1rias centenas a 3000 Gs; o separador magn\u00e9tico forte refere-se geralmente a 3000Gs a 6000 Gs, e o separador magn\u00e9tico de campo magn\u00e9tico m\u00e9dio entre os dois.<\/p>\n

A raz\u00e3o pela qual \u00e9 classificada de acordo com a for\u00e7a do campo magn\u00e9tico est\u00e1 relacionada com as propriedades magn\u00e9ticas de v\u00e1rios minerais comuns (outro post - Classifica\u00e7\u00e3o de minerais magn\u00e9ticos<\/a>). No entanto, \u00e9 necess\u00e1rio saber que n\u00e3o existe uma norma absoluta para as diferentes for\u00e7as magn\u00e9ticas e para o equipamento correspondente.<\/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> e electromagnetic magnetic separators<\/strong>.
\nO separador magn\u00e9tico de \u00edmanes permanentes utiliza um material magn\u00e9tico permanente, como ferrite ou boro de ferro neod\u00edmio, para gerar um campo magn\u00e9tico de trabalho, e o separador magn\u00e9tico eletromagn\u00e9tico utiliza um \u00edman com uma forquilha, um solenoide e um \u00edman para gerar um campo magn\u00e9tico.<\/p>\n

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

A intensidade do campo magn\u00e9tico do separador magn\u00e9tico de \u00edmanes permanentes \u00e9 fixa, mas as diferentes \u00e1reas de a\u00e7\u00e3o na superf\u00edcie de trabalho de separa\u00e7\u00e3o magn\u00e9tica podem ser concebidas para ter diferentes intensidades de campo magn\u00e9tico. O separador magn\u00e9tico eletromagn\u00e9tico pode ajustar todo o campo magn\u00e9tico, mas os valores de intensidade do campo magn\u00e9tico na superf\u00edcie de trabalho s\u00e3o um campo magn\u00e9tico equilibrado e uniforme.<\/p>\n

Consumo de energia<\/strong><\/p>\n

A energia magn\u00e9tica do separador magn\u00e9tico de \u00edmanes permanentes \u00e9 baixa, enquanto a separa\u00e7\u00e3o electromagn\u00e9tica requer um elevado consumo de energia para gerar a corrente de excita\u00e7\u00e3o. O consumo de energia por unidade do separador magn\u00e9tico permanente \u00e9 muito inferior ao do separador magn\u00e9tico eletromagn\u00e9tico.<\/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
