Effect of reduced iron powder particles on powder properties

The meaning and measurement method of particle size are different with different aggregation state and degree. The agglomeration state and degree of powder particles have great influence on the process properties of powder. In terms of the fluidity and bulk density of powder, the aggregated particle is equivalent to a large single particle, and the fluidity and bulk density are higher than the fine single particle, and the compressibility is also better. In the sintering process, the role of primary particles is more important than that of secondary particles.
