NPK was founded in 1916 and has a large number of domestic delivery records with supersonic jet mills and air classifiers.
It has established itself as an advanced material processing facility ranging from pulverization and classification of various ceramic powders, spheroidization of toner raw materials, Ni powder classification for MLCC, and pulverization and classification of sulfide-based raw materials for secondary batteries.
Classification example: Ni powder using EVX model
Before classification
D100=1.5μm
After classification
D100=300nm
