Materials that are size reduced using cryogenics are easier to clean than materials processed with ambient methods. Our cryogenic process uses liquid nitrogen at -325F to embrittle resilient materials before shattering to obtain size reduction. Ambient methods require many sharp knives to cut and chop / rip and tear resilient materials apart and away from contaminates. Unfortunately knives lose their pristine edge after the first few hours of operation and they begin to pound and chafe the material into submission. This chaffing effect creates very fine nuisance dust that is attracted to other, larger rubber granules. The nuisance dust is very difficult to clean away from the target size reduced granules and the net effect is the finished product is “dirty”. Our cryogenic method does produce fine particles but they are easy to separate by standard sifting / screening methods. The bottom line is that there's virtually no nuisance dust produced.
