METHOD FOR SEPARATING JELLY FROM JELLY CABLE FOR COMMUNICATION

摘要

The present invention relates to a method for treating a waste jelly cable, which is a technology capable of separating jelly while preventing damage to a sheath and the generation of harmful gas during the disposal of the waste cable. For the above-mentioned, the disposal method of multiple cables which respectively have jelly coated on a sheath surface includes: a jelly heating and separating process which melts the jelly and allows the jelly to flow down and to be separated from the sheath surface of the cable by reducing oxygen in a heating space in a state of sealing the heating space in a heating furnace and heating the internal space of the heating space in the sealed state by an electrical heating method; a pulverizing and separating process which separates the sheath from the inside a copper line by pulverizing the cable from which the jelly is separated; and a selecting process which separately selects the pulverized copper line and the pulverized sheath.
