In our view, there is a way to add liquid nitrogen for low temperature freezing during the crushing process, because liquid nitrogen is not flammable and explosive, nor toxic, but because it is a liquid formed by nitrogen compression, the expansion coefficient is very large, so when using this substance, it can not be used in a closed crusher. Because the volume of liquid nitrogen will expand to unimaginable limits during the sublimation process from liquid to gas, which will cause the risk of explosion, the first consideration is to use the pulverizer unit that collects the finished product while feeding the liquid nitrogen.
1. For heat sensitive materials and high toughness materials (such as plastics), the machine can be equipped with liquid nitrogen tank and filled with liquid nitrogen to the grinding chamber for low temperature grinding.
2, liquid nitrogen low temperature grinding can be combined with liquid nitrogen valves containing liquid nitrogen containers.
3, when using, follow the following steps:
a, liquid nitrogen outlet pipe closed circuit link, start the crusher;
b, open the liquid nitrogen control switch, liquid nitrogen into the crusher chamber, and then feed.
4. When stopping, follow the following steps:
A. About half a minute to one minute after stopping feeding, turn off the power of the crusher;
b, close the liquid nitrogen control valve;
c. Remove the liquid nitrogen tank for cleaning.
5, cleaning, please wear thick gloves, pay attention to prevent frostbite.
