Reduced iron powder application

Reduced iron powder, grey or black powder, also called double suction agent, able to absorb moisture and oxygen in the air, often used in food preservation Reduced iron powder by ferroferric oxide commonly under the condition of high temperature on hydrogen flow or carbon monoxide reduction in gas generated, main ingredients for the loose structure of elemental iron Because of reduced iron powder for powder itself, coupled with its microstructure is very loose, so its surface area is great In the chemical production and laboratory operations often used as a reductant.

The reduced iron powder is easy to oxidize, so it must be crushed and graded in the state of protective gas. In general, the JZDB nitrogen protection comminution classifier is used for ultra-fine grinding and grading. If the reduced iron powder is only used for high-precision classification, the JZDF nitrogen protection classifier can be used.
