Product Detail

rotor mill for powder coating

Working Principle

  The materials are evenly sent into the crushing chamber by the feeding system, and are strongly impacted by the high-speed rotating crushing disk. The crushing rotor is composed of multi-layer crushing disk and multiple crushing blades. The materials are crushed by shear, collision, friction and other crushing forces. The qualified materials enter the collection area for collection with the updraft, and the coarse materials return to the crushing area for secondary crushing.


  It is especially suitable for dispersing and reducing agglomerated materials, such as light calcium, kaolin, aluminum hydroxide, magnesium oxide, polyvinyl alcohol, PVC, PE, cellulose and other heat sensitive materials. Widely used in non-metallic minerals, chemical industry, fuel, feed, food and other industries.
