Method and apparatus of recycling previously used agricultural plastic film mulch

摘要

A method and apparatus for recycling previously used agricultural plastic film mulch in which the plastic film mulch is fed by a conveyor along a predetermined path of travel, while being agitated and shaken on the conveyor to dislodge and remove dirt and debris therefrom, shredding the plastic film mulch into discreet pieces in a shredder while removing additional dirt and debris therefrom, conveying the shredded plastic film mulch through a vertical separator along a second, tortuous path of travel, while drying the shredded plastic mulch by heated air and agitating the plastic film mulch by projections extending into the second path of travel to dislodge and remove still further dirt and debris therefrom, and extruding the cleaned and shredded plastic film mulch into a reusable form in an extruder, which melts the plastic film mulch, screens solids from the molten plastic, and extrudes the molten plastic into a reusable form, such as pellets.
