The ultrafine pulverizer complete system is composed of silhouses, mechanical pulverization machines, draunht fan, cyclone, vibrating screen, liquid nitrogen tank, etc., the deep-cooling pulverizer system Nitrogen as a cold source, the pulverized material enters the mechanical pulverizing cavity by cooling (Cooling) to enter the mechanical pulverizing cavity through the impeller (rotating the wheel of the moving leaves), material and blade, teeth The crushing effect is achieved under the combination of mutual repeated impact, collision, shear, friction between the disc, material and materials. Airflow pulverizer and cyclone separator, dust collector, and airplane set into a set of pulverization systems. The main applicable pulverization mechanism determines its scope, high finished product, typical materials are: super hard diamond, silicon carbide, metal powder, etc. After the crushed material has a gas flow sieve classification machine to grace and collect: the material that does not reach the fineness requirements return ultrafine pulverizer is continuously pulverized, and most of the air-conditioning is used back to the silo cycle. The deep-cold pulverizer system has a closed circuit circulation system in the material pulverization process, which enables energy (explanation: substance to provide energy conversion to nature), saving (SPARE) energy consumption. The cold source temperature (Temperature) for ultrafine pulverizer can be reduced to a negative 196 degree, depending on the brittle point temperature of the material, the temperature (Temperature) can be regulated (interpret: adjustment, control), Choose the best pulverization temperature, reduced energy consumption: The pulverization fineness can reach 10-700 mesh, even to the fineness of micrometers: Using liquid nitrogen as a grinding medium (substance determined by determining), ultra-low temperature pulverization Comprehensive effect of explosion-proof, oxikenization, and oxiDance.
