Patent ID: 6893862

Claim:
A method of producing a drum and paddle assembly for the accelerated remediation of a contaminated material which comprises: providing at least one paddle and an elongate cylindrical drum having a longitudinal axis, each said paddle being connectable to, and extendable outwardly from the periphery of, said elongate cylindrical drum, for generating an air stream at a velocity sufficient for entraining the contaminated material therein, and for microenfractionating said contaminated material so that said contaminated material is treated with at least one chemical amendment prior to, and/or during, and/or subsequent to, microenfractionating said contaminated material, each said paddle comprising a body having a first planar portion having a leading edge and a second planar portion connected at a first angle to the first paddle portion, the second planar portion being oriented so as to generate a first material-entraining air stream when the drum is rotated, and a base portion connected to the body for mounting the paddle onto the drum; and mounting at least one said paddle onto said drum.
