Ambient vs. Cryogenic Rubber Grinding Eco Green Equipment

Aug 09, 2020· Cryogenic grinding starting with rubber that has been coarse ground to two-inch minus, it can produce a fine grind, ¼ inch minus to 30 mesh, in fewer steps at a rate of 4,000-6,000 pounds per hour. In this method, liquid nitrogen is used to freeze the rubber, which is then “shattered” as it passes through a hammer mill.

Cryogenic grinding: an efficient method for recycling

Cryogenic grinding represents an opportunity for expanding recycling capabilities to a broad range of compounds. By using a super-cold agent such as liquid nitrogen at -320 degF to embrittle plastic rubber polymers before grinding, cryogenic grinding makes possible the size reduction of many materials that cannot be ground by conventional ambient grinding methods.

Cryogenic Grinding & Attritors Union Process Inc

Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling.

Cryogenic grinding of thermoplastics and elastomers

On the other hand, the duration of the grinding process should be kept as short as possible, because the material to be ground, which is heated again by the energy input of the grinding tools, should not be deformed but be grinded. The objectives of the cryogenic milling of thermoplastics and elastomers are:
