materia ike tires and storage batteries to a refuse container. Remaining mateia is paced on a crusher feeder

which meters it into the crusher.A vibrating feeder instaed beow the crusher con

tros the feed of crushed materia to an incined betconveyor which discharges to a conveyor incorporatinga nger screen deck The various size crushed materiaswhich woud otherwise catch in a conventiona perforated or wire mesh screen are ecienty separated by

ay incude a series of verticay spaced steps between

screen sections to aid in the turnover of materia as it

drops onto the foowing section Large buky items

and other undesirabe materias such as carpeting or

tanged wire which bypass the crusher are manuay

removed to containers.

Materia remaining on nger deck passes beow overhead in-ine magnet which discharges ferrous materia

into materia container and aows the remaining mate

ria to discharge onto an innovative vibrating/pneu

arates and cassies mixed buk materias on the basis

of density and partice size.
