Jiyu Mill (Mill)

Product Outline

Rotor is fixed with striking pins and rotates at high speed, whereby exerting a strong impact to the raw materials. This high speed impact type pulverizer is capable of super-fine mass milling pulverization in a short process time. We have lineups from compact type to heavy production type for your selection of the most appropriate model. Thanks to its solid and simple construction, milling pulverization of any kind of materials is possible, and it is widely used as standard industrial impact type pulverizer.


  • Cosmetics, Electronic material, Ceramics, Synthetic, resin, Pharmaceutical, Metal, Foodstuffs, Feed/Fertilizer, Materials for Biomass feedstock
  • Mineral, Fiber, Wood/Paper, Pigment/Paint, Building material, Cosmetics, Rice powder


  • Super-fine mass milling pulverization is available in a short process time.
  • Rotor generates wind which controls rise in temperature of processed product.
