磁铁矿介绍：

    磁铁矿Magnetite为氧化物类矿物磁铁矿的矿石。属等轴晶系。晶体呈八面体、十二面体。晶面有条纹。多为粒块状集合体。铁黑色，或具暗蓝靛色。条痕黑，半金属光泽。不透明。无解理。断口不平坦。具强磁性。性脆。无臭，无味，常产于岩浆岩、变质岩中。

    磁铁矿为一种具有亚铁磁性的矿物，其富含四氧化三铁。产于变质矿床和内生矿床中，氧化后变为赤铁矿或褐铁矿，是炼铁的主要原料。

磁铁矿特点：

     磁铁矿具有半金属光泽，不透明，无解理，断口不平坦，硬度5.56.5，密度5.165.18g/cm3，具强磁性，性脆，无臭，无味。磁铁矿滤料具有过滤速度快、截污能力强、使用周期长等特点。磁铁矿滤料外观呈球状，机械强度高，不含有毒有害物质。

磁铁矿用途

    磁铁矿滤料呈棕褐色颗粒状，是三层滤料滤池的理想材料。目前我们厂生产的磁铁矿滤料是由含铁40-42的磁铁矿中精选而成的。它具有过滤速度快、截污能力强、使用周期长等特点。

    正因为磁铁矿的这些性能，所以适用于管式大阻力配水系统，通常与无烟煤滤料和石英砂滤料配合使用，主要对改进承托层和配水系统有着良好的适用能力，强度高、滤速快、反冲洗时不易混层。另外，它对除铁、除锰、除氟效果也很明显，广泛用于给排水、冶金、电力、化工、石油、环保、轻纺、造纸、制革等领域。对提高生活饮用水、高纯水净化、工业污水处理质量、延长供水设备寿命等起到了很大作用。

    在双层(多层)滤料过滤中，磁铁矿滤料都是较合适的的主要过滤材料，磁铁矿滤料由于使用的颗粒粒径较小，在双层(多层)，滤料过滤中都是起着处理水质末道把关的作用，因此磁铁矿滤料质量是否合格直接关系到水处理的水质。

    在国内大多数工业水处理中，采用的过滤形式都是压力过滤形式，压力过滤器的过滤压力和反冲洗压力都比较大，所以在垫层中使用比重大的磁铁矿垫料，可以随较大的反冲洗压力。如果使用比重小或不合格的垫料，容易造成滤料和垫料在反冲洗过程中出现混层，过滤器很快失去过滤作用。在水过滤行业磁铁矿滤料成为了大多数厂家选择的滤料。

运输注意事项：

    磁铁矿选用耐用编织袋包装净重25kg（也可按照客户要求包装），粒径小于0.5mm的磁铁矿滤料，加内层塑料袋，也可用吨袋包装。 运输储存期间防止包装破损，以免漏失或混入杂物．不宜与承托料及其他滤料一起运输栈放。

Magnetite introduction:
Magnetite Magnetite as oxide mineral magnetite ore. Axis of the genus. The crystal is eight face and twelve face. Plane with stripes. Multi - particle aggregation. Iron black, or a Dark Indigo color. Streak black, semi metallic luster. Opaque. No cleavage. Fracture surface is not smooth. Strong magnetism. Brittle nature. No smell, tasteless, often produced in magmatic rock, metamorphic rock.
Magnetite is a ferrimagnetic minerals with. It is rich in magnetite (chemical formula for Fe o, relative molecular mass for 231.54). In the metamorphic deposits and endogenetic deposits, after oxidation into hematite and limonite, is the main raw material for ironmaking.
Magnetite characteristics:
Magnetite with semi metallic luster, opaque, no cleavage, fracture is not flat, hardness 5.5 6.5, the density of 5.16 to 5.18g/cm no, with strong magnetic, brittle, odorless and tasteless. Magnetite filter material has the characteristics of high filtration speed, strong interception capacity, long using cycle, etc.. Magnetite filter material appearance is spherical, high mechanical strength, does not contain toxic and harmful substances.
Magnetite application
Magnetite was brown granular, is three layers of filter material necessary. At present our factory production of magnetite filter material is made of iron containing 40-42 of magnetite in the selection of. It has the characteristics of high filtration speed, strong interception ability and long using period.
Because of magnetite of these efficient performance. So it is very suitable to the tube type resistance water distribution system, usually and anthracite coal and quartz sand filter material to cooperate to use, mainly on the improvement of the supporting layer and water distribution system has good adaptability, high strength, fast filter, backwashing when the mixed layer is not easy. In addition, it on the removal of iron, manganese, fluoride removal effect is obvious. It is widely used in drainage, metallurgy, electric power, chemical, petroleum, environmental protection, textile, paper, leather and other fields. It has played a great role in improving the quality of drinking water, high purity water purification, industrial wastewater treatment, and prolonging the service life of the water supply equipment.
In most domestic and industrial water treatment, using forms of filtering is form of a pressure filter, filtration pressure of the pressure filter and a backwashing pressure are relatively large, so used the cushion than major magnetite litter can with great backwash pressure. If the use of small specific gravity or non qualified material, easy to cause the filter material and the material in the process of anti - flushing mixed layer, the filter will soon lose the filter. Magnetite in the water filter industry has become the best choice for the majority of manufacturers.
Transportation matters needing attention:
Magnetite choose durable woven bag packaging net weight 25kg (also according to customer requirements for packaging), particle size of less than 0.5mm of magnetite, layerplus inner plastic bags, tons of usable bag packaging. Transportation and storage period to prevent breakage of packing, in order to avoid leakage or mixed with debris. Not with supporting materials and other material transportation stacked together.
