Abstract: A jet milling mechanism includes an impeller with a plurality of rotating members mounted for rotation in a housing. Each rotating member has multiple negative pressure blades formed thereon for producing multiple negative pressure zones therebetween and multiple positive pressure blades formed thereon for producing multiple positive pressure zones between the positive pressure blades. The pressure blades define at least four grinding areas each distributed circumferentially about the rotating member. Each of the negative and positive pressure blades has a straight portion and an arcuate portion, and upon rotation of the impeller, the pressure blades divert material-containing air to flow into corresponding grinding areas sequentially in one direction by way of the negative pressure zone and in another direction by way of the positive pressure zone to define a two-phase flow. The jet milling mechanism is installed on a motor shaft of a jet mill.
