Dry Burst DB-180W: Twin Impeller Counter Current for Small Scale Production Dry-type Milling Equipment


Compact dry-type milling equipment with excellent maintainability!

The "Dry Burst DB-180W" 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
1-20 kg/hr


  1. High pulverization capability
    The unit's counter air flow enables micron-order pulverization, while also producing a sharp particle size distribution.
  2. Low thermal effect
    The unit comes with a standard water jacket that helps to minimize the thermal effect.
  3. Highly maintainable
    The pulverization compartment can be opened without the use of any tools, making access easy during maintenance work.
  4. Space-saving
    The main body of the unit is compact with a width of 1,030 mm, depth of 515 mm, and height of 1,070mm.
  5. High reliability
    The unit makes use of our proven high-precision mechatronics and know-how in atomization technology.
