Cryogenic Regrinding Of Rubber Sciencedirect

Jan 01, 1981 The cryogenic method, in which vulcanised rubber is taken below its embrittlement temperature and then converted to a powder under high shearing conditions, has been found not only useful for separation of non-rubber components from the rubber, but also for allowing size-reduction of the rubber itself.

Micronized Rubber Powder By Cryogenic Grinding

Cryogenic processing refers to the use of liquid nitrogen to freeze tyre chips or rubber particles prior to size reduction. Most rubber becomes brittle or glass-like at temperatures below minus 80 C. This process can be used to produce fine micronized rubber powder ranging from 80 mesh size 177 microns to 300 mesh size 50 microns.

Production And Applications Of Crumb Rubber Ecomena

Dec 09, 2018 Crumb rubber is a term usually applied to recycled rubber from automotive and truck scrap tires. There are two major technologies for producing crumb rubber ambient mechanical grinding and cryogenic grinding. Of the two processes, cryogenic process is more expensive but it produces smoother and smaller crumbs.
