Abstract:
A high efficiency system to process material into fiberized, low bulk density treated material, comprising:a cyclonic mill, comprising a housing having a chamber formed therein, said chamber having a top, bottom and medial area therebetween as well as inner walls, said inner walls being cylindrical in the vicinity of the top of said chamber, inner walls having a taper from wide to narrow from said medial area to said bottom of said chamber, respectively, said top of said chamber having emanating therefrom a conical insert having a taper aligned to said taper of said inner walls of said chamber, said cyclonic mill having an intake port formed through said cylindrical, inner walls formed in said chamber, and an outflow port formed through said top of said chamber in the vicinity of said conical insert, said bottom of said chamber having formed therein an adjustable passageway for selectively venting material from said chamber; air generating means to generate a high velocity stream of air; heating means to heat said high velocity stream of air; means to direct said high velocity stream of air into said intake port of said cyclonic mill; feeder means to feed material into said high velocity stream of air, and direct said material into said cyclonic mill, said cyclonic mill configured to fracture, fiberize, and dry said material; recirculation means for recirculating a portion of said material through said adjustable passageway to said top of said chamber; separation means to separate treated material from debris.
