Dry Burst DB-320W: Twin Impeller Counter Current for Medium Scale Production Dry-type Milling Equipment

Compact dry-type milling equipment for medium scale production
The "Dry Burst DB-320W" is a space-saving dry-type milling device that supports continuous production of low-contamination powder with a particle diameter of less than 10 µm. The powder is produced by colliding the raw material particles with one another using the air flow generated by two rotating impellers. Compared with jet mills, the particle diameter can be better adjusted without over-pulverization. Furthermore, the running costs are lower since the unit's power consumption is low. Processing capacity 5-100 kg/hr

High pulverization capability

The unit's counter air flow enables micron-order pulverization, while also producing a sharp particle size distribution.

Low Thermal Effect

The unit comes with a standard water jacket and an air classification that helps to minimize the thermal effect.

Easy to Maintain

The pulverization compartment can be opened without the use of any tools, making access easy during maintenance work.


The main body of the unit is compact with a width of 1,280 mm, depth of 1,000 mm, and height of 970 mm.

High Reliability

The unit makes use of our proven high-precision mechatronics and know-how in atomization technology.

Application Examples

  • Inorganic materials (electronic parts materials, etc.)
  • Organic materials (pharmaceutical raw materials, food, and biomass)
  • Wet materials, etc.
