Comminuting apparatus and method

摘要: An apparatus for breaking-up or pulverizing particles of solid material, comprising a chamber defined by wall having substantially shape revolution with respect to an axis; at least one rotor disposed coaxially in the interior said and cylindrical body provided centrifugal flow means be pulverized, being uniformly distributed angularly axis chamber, each extending radially from internal extraction extremity located axial receiving zone particles, up external projection outer periphery rotor, front surface (with direction rotation rotor) displacement particles; introducing pulverized into rotor; annular target constituted, if so desired, surrounding evacuation communication peripheral vicinity target; driving shaft passing through pulverization further blade entirely concave profile pulverized. The invention also covers method utilizing this step recycling part fluidization carrier gas separation collection thence chamber.
