Process and apparatus for comminuting particle rubber.U.S. patent: 7,108,207 Issued: September 19, 2006 Inventors: Peter J. Waznys, George W. Meckert and Anthony M. Cialone Assigned: Lehigh Technologies, LLC (Logical Link Control) See "LANs" under data link protocol. LLC - Logical Link Control Key statement: The rubber particles, at a room temperature below the glass transition temperature The glass transition temperature is the temperature below which the physical properties of amorphous materials vary in a manner similar to those of a solid phase (glassy state), and above which amorphous materials behave like liquids (rubbery state). , are introduced into a comminuting device concurrent with the introduction of an inert gas coolant coolant (kōō´l  nt),n at a temperature below about -75[degrees]F and are comminuted comminuted /com·mi·nut·ed/ (kom´in-ldbomact?id) broken or crushed into small pieces, as a comminuted fracture. com·mi·nut·ed adj. Broken into fragments. Used of a fractured bone. at a rate proportional to the average particle size of the introduced rubber particles to an average size within the range of crumb or powder rubber particles.
