For fine coal, a new separation equipment appears to help achieve the goal

Dry magnetic separator for dry magnetic separation of magnetic minerals beneficiation machinery, as opposed to wet magnetic separator to use when sorting mineral liquid as a diluent to improve separation efficiency, the dry magnetic separator is required to be separation of the mineral drying, particles can move freely, into independent free state, otherwise it will affect the magnetic effect, or even result in non-separation of the consequences.

As to the popular separation equipment, many manufactories and specilists make lots of researches to analyse and improve it. Therefore, a new separation equipment - dry permanent magnetic separator of fine coal appears.

Dry magnetic separator equipment is commonly used iron and manganese equipment, mainstream intensity magnetic separator mineral processing equipment. This series of dry magnetic separator for refractory, chemical materials, grain and oil machinery, abrasives, ceramics, metallurgy, cement, powder metallurgy, rubber, minerals and other materials in addition to (optional) Rail, and with Raymond , mill, ball mill supporting the use of.

It's popularized that dry permanent magnetic separator for coal separation in order to achieve desulphurization and dust reduction to ease enviromental pollution. However, due to weak magnetic coal minerals, conventional magnetic separator is far from for effective separation of fine coal. And the new permanent magnetic separator with reasonable magnetic system design is validated through mathematical modeling and analysis. At the polar distance of 0.45mm within the separation space, magnetic field strength can up to 1.3T. The new magnetic separator was used for different power plant for dry coal separation test, When the particle size is below 0.074mm, the desulfurization rate is 52.57%, 48.95%, respectively; and ash removal rate is 41.79%, 43.95%, respectively. The magnetic separator can achieve the dry coal pyrite separation; it also provides technical support for effective solution in coal-burning air pollution.
