The technology of magnet mineral powder makes our work like a fish in water, and the technical requirements of magnet mineral powder for coal washing are the focus of common attention.

The requirements of coal preparation plant for magnet mineral powder: the medium for coal preparation of magnet mineral powder is a magnet mineral powder, which consists of magnetite, hematite and pyrite. Different origin, different chemical composition and magnet mineral powder, its physical properties are also different. Coal preparation plant has high requirements on the density, particle size and magnetic content of magnet mineral powder.

The main technical indicators are: 1. The content of magnetic material should reach more than 95%; 2. The true density of magnet mineral powder should reach 4.5kg/cm3; 3. In the particle size composition of magnet powder, the particle size content of less than 0.045mm should be higher than 85%; 4. Inclined wheel (or vertical wheel) heavy medium separator for the selection of lump coal magnet powder, particle size less than 0.075mm content should reach more than 90%.
