A system and method for separating polymer components of a multi-component article, such as a shoe, is presented. The described system and method exploits the differences in embrittlement and glass transition temperature of different polymer components of the multi-component article by cryogenically freezing the prepared article and impacting the article such that one polymer component is pulverized without substantially fracturing the remaining portion of the article. The system and method further includes a re-looping capability to maximize separation and recovery of polymer components. |

The raw material in used tire carcasses is reclaimed by cutting the tire into quarter segments and freezing the segments with liquid nitrogen in a controlled environment freezing chamber. Rotary air locks pass material to and from the chamber. Steel and fiber materials are removed in a stripping chamber where the frozen rubber both broken into smaller chunks. A robot arm with magnets and hooked fingers removes the fiber and steel. The rubber chunks are then pressed through dies to reduce the size to a uniform rubber crumb. The press consists of multiple pointed fingers in registration with multiple sized holes in a screen type die. The rubber crumb is removed with a suction device and dried using heat from a closed loop nitrogen cycle on the way to collection containers. |

Harold Perkel |
A process and apparatus for the low temperature comminution of tires includes the separation of the tires into tire portions including tread portions, sidewall portions and bead portions. The tire portions are cooled and crushed to form rubber granules and scrap material. The rubber granules are sorted from the scrap material in a process that includes the step of suspending the granules in a moving stream of low temperature gas. The stream of gas and rubber granules is impacted on a solid surface to grind the granules. The low temperature gas is preferably recycled and cooled by heat exchange with another circulating low temperature gas such as nitrogen. |

Automobile tires and analogous articles of rubber or synthetic plastic material are frozen to make them brittle, and thereupon are fragmented in order to separate their rubber or synthetic plastic material from embedded reinforcements of textile or analogous fabrics. The fragmenting is carried out by dropping the articles into an impact mill in which a rotor equipped with striking elements turns about a horizontal axis, so that the articles are hit by the striking elements of the rotor and flung in circumferential direction of movement of the rotor against impact plates from which they drop back onto the rotor, whereby the articles are fragmented by the repeated hits and impacting. An apparatus for carrying out the method is also disclosed. |

The crushing apparatus comprises a housing, a route provided in upper portion of the housing for throwing matters to be disposed of, a rotary hammer provided in lower portion of the housing, a screen provided below the hammer, and a route provided above the hammer for exhausting floating matters. Completely crushed matters among the matters to be disposed of, are taken out of the screen, and the uncrushed matters among the matters to be disposed of, are floatingly selected through ascending air currents caused, within the housing, by rotation of the hammer and, thereafter, are taken out of the housing through an exhausting route.
