Whole tire size is reduced by various means Tires are then fed into cryo chamber and frozen with     liquid nitrogen to -184º C (-300º F) Hammer mill reduces crumb to particles of various sizes Steel is removed magnetically throughout process Particles are sorted and screened to specified size Fine grinding reduces further particle size if needed

Scrap tires are collected and reduced by various means.

Then fed into cryo chamber Frozen with liquid nitrogen to -184º C (-300º F)

Steel and non-reclaimed rubber particles are removed.

Particles are separated into various sizes.

Crumb rubber particles are bagged by particle size and stored in 1-ton Supersacks.

Crumb rubber particles from a cryogenic-grind process have an angular or prismic shape, smooth surfaces and low surface area.
