genic grinding. This involves grinding aids such as liquid nitrogen (-196 °C) or dry ice (-78 °C) which embrittle the sample by cooling and make it break more easily. Another advantage is the preservation of volatile components of the sample. In this white paper we explain for which sample materials cryogenic grinding is

Waste Tyre Recycling | Environmental XPRT

In case of cryogenic grinding, one phase normally suffices for reaching the requested separation of the components and obtaining a broad particle size spectrum of rubber crumb. A disadvantage of this technology is the high cost for the use of liquid nitrogen, since one to two tons of LN2 are required for one ton of waste tyres.
