To All:
It sure is nice to see some discussion here for a change. I had about given up on trying to create any interest.
If you will go back to about post # 359 you will find a response to me from a person that studied this rubber subject in 1990.
Ed, I believe FASC is capable of producing a grade of crumb much smaller than the existing industry and would be purchasing rubber that had already been thru the preliminary stage of reduction, I may be wrong here but otherwise they would just be reinventing.
The following is information about a company that is in the business of crumb rubber GMTI. If you want more information- go to your net search and simply type in "Crumb rubber". There is a national and international Association for those in the business and also for marketing. As you will see, this company and others have apparently solved their cooling requirements with the cooperation of NASA and their program of sharing technology with private industry.

GreenMan Technologies(GMTI): Purchased Tire Div from RII (Republic Ind.)
PRODUCTION OF RECYCLED RUBBER PRODUCTS
Used tires can be recycled if the rubber can be separated from the steel and cloth fiber tire bodies. GreenMan Technologies of Louisiana, Inc. (formerly Cryopolymers, Inc.) uses liquid nitrogen to supercool tire chips so that they become brittle.
The chips are then pounded by a hammer mill which breaks the rubber from imbedded steel wire and cloth fiber. The resulting product is termed "crumb" and varies in size from 850 micron to 75 micron. The Louisiana plant is responsible for the production of ultra-fine crumb rubber powders for use in markets such as modified crumb rubber for asphalt, new tire manufacture, and internal use in the company's proprietary materials made from recycled plastics and rubber
from tires. GreenMan Technologies of Louisiana is a subsidiary of GreenMan Technologies, Inc., which manufactures products and materials made from recyclable tires and plastics.

NASA Involvement:
NASA expertise in the handling, application, and properties of cryogens were used to make the crumb manufacturing process safe and efficient. Other NASA expertise in instrumentation and measurement systems, as well as automated computer control systems, were used in
manufacturing control process.
Social/Economic Benefit:
1) For each pound of rubber salvaged, nearly 90 percent is reduced into crumb.
2) More than 260 million tires are discarded in the U.S. annually. Recycling of tires alleviates environmental and health hazards and the need for unsightly and unwanted landfill sites.
