ABSTRACT:
Apparatus for cryogenic separation of elastomeric products from metallic products and textile fibers combined as composite waste products having two cryogenic chambers capable of alternately receiving waste composite products to be directly contacted by a cryogenic fluid and for alternately discharging cryogenically frozen products therefrom. The chambers are in communication through a valved duct for transferring the cryogenic fluid from one chamber to the other alternately and there is a pressure equalizing valved duct to facilitate the fluid transfer in an equalized pressure environment. The chambers are rotatable through an angle sufficient to permit the cryogenic fluid transfer to be effected by gravity from one chamber to the other alternately, so that when one of the chambers is operating as a cryogenic chamber, the other can be discharged and reloaded and vice-versa. The cryogenic fluid is fed to the chamber operating as a cryogenic chamber in each cycle only to replenish the amounts lost through evaporation.
