Crushing principle:
the material through the use of the cold source and heat exchange;
to cool down to the brittle state of the material; brittle material
after grinding in the grinding chamber by numerous institutions
impact, shear, friction and eventually become a fine particles,
crushed fineness of the output material can be up to micron level
(**0 ~ ***0 mesh). The performance of materials selected according
to the cold to seek, such as using liquid nitrogen as a refrigerant
for cooling the lowest temperature can reach minus **6 degrees, the
cooling speed is very fast, which need rapid cooling, low
temperature embrittlement of materials is the preferred coolant.
Less demanding on the cooling temperature of brittle materials can
be used pre-compressed air or air-conditioners have heat exchange
with the material cold.
