Shredded tire oversize scrap return elevator

摘要

There is disclosed in a unitized automotive vehicle tire shredding system a rotating drum type elevator for receiving from a screening device heterogeneously mixed scraps of shredded tires or the like which include components of curvilinear shape and resilient characteristics. The drum carries the scraps to an elevated point of discharge to fall therefrom by gravity into a shredding machine and from there down again upon the screening device. The drum includes an annular trough-like portion for carrying the scrap when deposited into a lower portion thereof upwardly to the point of discharge when the drum is rotated, and a material travel control device comprising a trough-shaped channeler of convergent sectional form having side walls peripherally configured to complement the curvatures of said rim and flange wall members. The control device is stationarily mounted interiorly of said drum in open-facing opposition to the rising segment of said drum when rotating and receives and funnels into increasingly densified condition the scrap materials during the elevating process.
