Particle size distribution (PSD) requirements vary significantly across different applications: lithium-ion battery anode materials typically require a D50 of 4–20 μm with a narrow distribution; coating raw materials generally demand particles below 200 mesh (~75 μm), as excessive fineness can compromise gloss; coal water slurry requires particles under 1 mm, since over-grinding may reduce combustion efficiency.

Ultrafine powder (typically defined as particles <4μm) is a critical control parameter in powder processing. Taking lithium-ion battery anode materials as an example, excessive <4μm ultrafine powder content after petroleum coke grinding can lead to reduced compaction density and lower battery capacity;
