摘要:
A method is provided of rapidly increasing the bulk density of an iron oxide powder by preventing the powder, processed by a roller consolidtion machine, from flying up. The method consists of feeding an iron oxide powder, whose apparent bulk density is 0.4-0.6, into a sealed tank, depressurizing the tank to a vacuum of 100-200 torr, and revolving the rotating roller and rotating plow at a revolving speed of 1-2 m/sec.
