A system and method of processing bone is disclosed. A tissue separator is utilized to separate tissue comprising at least one of muscle, periosteum and connective tissue from bone in a safe, sterile and efficient manner. In one aspect, the particle reducer can include an impeller positioned with respect to a cutting surface on a drum. At least one of the impeller and the drum is rotated by a power source such that harvested tissue frictionally engages the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.

A mill for the comminution of particulate material by impact means including a shell rotating at super critical velocity and a gyrating mandrel. Material introduced to the mill forms a bed on the inner surface of the shell and is then crushed by the impact of the gyrating mandrel. The axis of rotation of the shell is in angularly displaced from the axis of gyration of the mandrel to transport material through the mill.

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.
