Hosokawa Micron
Pulvis PV

General

Pulvis was developed as an energy-efficient ultra-fine grinding machine.
This high-efficiency mill produces sub-micron size particles.

Construction

The milling part is located at the bottom of the machine.
Feed material is ground by agitated media, which generate forces of hitting, compressing, shearing and friction.
Ground particles are conveyed by air, passing through the grinding chamber, to the classifier. The classifier separates the required fine product from coarse particles.
The coarse particles return to grinding zone.

Features

• Energy Saving
  With high grinding efficiency specific energy consumption is reduced by more than 80%. Finer particle sizes are possible compared to jet milling.
  
• Ultra-Fine Particle
  The high speed air classifier produces sub-micron particles with high great efficiency.
  
• Wear Protection
  Grinding parts and classifying parts are available in ceramic material of construction.
• Easy Access
  Easy assembly, disassembly and cleaning are achieved with this design. Ideal machine for frequent material changes.
• Adjustable Particle Size
  Fineness is determined by changing the classifier speed.
  
• Test Equipment
  It is possible to test to confirm scale up for production runs.
  

Application

Ceramic materials, Metal oxides, Battery materials, Minerals, Glass, Hydrogen absorbent alloys, Magnetic materials, Pigments, Carbon, etc.

Flow sheet

This is a typical flow system for the Pulvis, which consists of a feeder, blowers and powder collector.
Depending on the material, a closed nitrogen circuit system is available.
