Achieving powder surface modification by changing the cyclone vortex

  • Relative motion of the three rotors modifies the impact of cyclone swirls to coat the powder's surface.
  • Mature technology requires minimal initial investment, hence making it suitable for stearic acid coating.
  • Heat generated through self-friction and no additional heat source is required. As a result, the amount of auxiliary equipment and the cost for operation is kept to a minimum.
  • Suitable for 325 ~ 1250 mesh powder coating.
  • Power range: 11 kW ~ 225 kW
  • Maximum output: 6 t/h

    2. Drying & Dispersing The usage of powder products used in food, medicine, fertilizer, pesticide and other industries is sometimes hindered by the caking during transportation and storage.
    1. Classifying & Separating
    2. Classifying & Separating Classification and separation involve the sorting of particles according to their size. This is done by subjecting them to centrifugal force, gravity, inertial force and other forces in a medium such as air.
