Cost Of Cryogenic Grinding Machinery. cryogenic grinding comes at a cost however liquid nitrogen while common and easily attainable can cost a recycling company 2 to 6 cents per pound of rubber depending on the desired rubber particle size and the quantity purchased.

Cryogenic grinding also known as freezer milling freezer grinding and cryomilling is the act of cooling or chilling a material and then reducing it into a small particle size For example thermoplastics are difficult to grind to small particle sizes at ambient .

The use of liquid nitrogen to chill the pellets enables more effective size reduction. Cryogenic grinding can be mechanically difficult, requiring expertise to manage moisture, clumping and other important quality elements. Why use cryogenic grinding: Some polymers require the use of cryogenic grinding in order to reduce the particle size.
