ABSTRACT:
Used automotive type oil filters are provided in drums to a tipper which operates to deposit the filters therefrom into a feed hopper. An input feed conveyor receives the filters from the hopper and conveys the filters to a coarse shredder. Shredded pieces are deposited from the coarse shredder onto a conveyor which deposits the pieces into a fine shredder from which the shredded pieces exit onto either another conveyor for transport to a hammer mill shredder or to a washer input conveyor for transport into a washing drum. A magnetic separator may be disposed between the hammer mill shredder and washing drum to separate out ferrous materials for transport to the drum. Oil that drips and seeps from the shredders, hopper and conveyors is collected in wells and conducted therefrom through filters and under pump action to a waste oil storage tank. The washing drum rotates at an angle to the horizontal and includes an auger on its inside face to conduct the shredded pieces through and out of the drum as well as screens at each end of the drum. Heated and pressurized water is sprayed onto the so conveyed shredded pieces separating oil, paper and metal.
