The production of superhard materials (such as diamond, cubic boron nitride, etc.) often involves the mixing of ultrafine powders, fibers or viscous materials, and traditional equipment is prone to problems such as nonuniform mixing and fiber agglomeration. For example, for the mixing of carbon fiber and powder, the mixing time of up to 4 hours can not nonuniformity disperse the carbon fiber using a double cone mixer and a vertical belt mixer. After using Zhengzhou Jinhe dual motion mixer, through the dual action of barrel rotation and high-speed flying knife, it only takes 10 minutes to realize the complete break of the fiber and the uniform mixing of the powder. Moreover, the high-speed flying knife mixer can also open viscous particles and plate agglomerates, which is suitable for the fine mixing of superhard materials such as diamond powder and metal powder, and solves the problems of large residual amount and low mixing efficiency of traditional equipment through the dual-motion mixer.
