Method for crushing and grading reduced iron powder

For atomization method or iron powder reduction process production process, the need for steel belt conveyor belt after the original furnace reduction of iron powder sintered powder block need to break up, because the iron powder particles, the more, the more easily oxidized, the high requirement of scattered, need a break in the case of a closed or in nitrogen gas as shielding gas dispersion under the condition of grinding So commonly used JZC grading type impact grinding scattered operations add nitrogen protection system, also called FenSuiFa airflow.

Airflow crushing method:

Nitrogen protective pulverizer is used to carry out ultramicrogrinding in nitrogen environment to prevent the oxidation of high-activity crushed iron powder. The use of airflow pulverization can make the iron powder with high hardness crushed to micron level. The use of nitrogen protection system is mainly to prevent the oxidation of iron powder and avoid dust explosion in the process of crushing.
