magnetite iron sand in other metals and metal prodacts from Chinese Manufacturer
Magnetite is a kind of filter material used in magnetite ore selection processing iron 40-52 and magnetite are mainly used to improve the ability of the supporting layer and the water distribution system, mixing layer of high strength, fast filter backwashing. Due to the smallest particle size, the magnetite filter can play a role in the filtration of water quality in the double layer (multilayer) filter.
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
Magnetite physical and chemical indicators
2.8 g / c m3
K80 ≤ 1.8
Magnetite Common size:
0.25~0.5mm 0.5~1.0mm 1.0~2.0mm 2.0~4.0mm
4.0~8.0mm 8.0~16.0mm 16.0~32.0mm
1, magnetite filter material containing iron 40-52 magnetite ore processing.
2, backwashing is not easy to mix. If the use of a small proportion of the material is not qualified or not, it is easy to cause the filter material and pad material in the backwash process of the mixed layer, the filter will soon lose the role of filtration.
3, it has long fast filtration speed, strong interception capability, long life cycle, the filtration rate can reach 30-40 M / h
4, I plant the production of magnetite filter material, the appearance of spherical, high mechanical strength, does not contain toxic and harmful substances.
