Liquid Nitrogen Crusher Cryogenic Pulverizer Grinder Powder
Grinding Machine
Cryogenic Pulverizer
1. Working principle and characteristics
The whole set of freezing pulverizer of this product is composed of
silo, mechanical pulverizer, induced draft fan, cyclone, vibrating
screen, liquid nitrogen tank, etc.
Working principle
The cryogenic pulverizer system uses liquid nitrogen as the cold
source. After the pulverized material is cooled at a low
temperature to achieve embrittlement and easy pulverization, it
enters the cavity of the mechanical pulverizer and rotates at high
speed through the impeller. The material and the blade, the toothed
disc, the material and the material Under the combined effect of
repeated impact, collision, shearing, friction, etc., the crushing
effect is achieved: the crushed materials are classified and
collected by the air sieve classifier; the materials that do not
meet the fineness requirements are returned to the silo to continue
crushing. Most of the cold air is returned to the silo for
recycling.
Features
In the process of material crushing, the cold source of the
refrigerated pulverizer system forms a closed-circuit circulation
system, so that the energy can be fully utilized and energy
consumption is saved: the temperature of the cold source used for
crushing can be reduced to minus 196 degrees, according to the
brittle point temperature of the material. , in the crushing
process, its temperature can be adjusted, and the optimal crushing
temperature can be selected to reduce energy consumption: the
crushing fineness can reach 40-200 mesh to micron μ and other
fineness: using liquid nitrogen as the grinding medium to achieve
ultra-low temperature crushing, the material The comprehensive
effect of explosion-proof and anti-oxidation.
2. Scope of use
The refrigerated pulverizer system is used for various materials
that cannot be pulverized at room temperature, and is widely used
in various chemical, petrochemical, machinery, shipbuilding,
automotive, electronic Hot melt adhesive, nylon, polyester,
polypropylene, polyethylene, food industry (chili powder), Chinese
and Western medicinal materials, nylon, polyester, hot melt
