The disperser is not only able to disperse the materials with low fineness requirement but also blend them into final products directly. Disperser’s saw tooth-shaped dispersing impeller intensely stirs the paste in the vessel while rotating at high speed. The material particles become finer particulates during strong impact and shearing force. The mixing impeller blade is fabricated according to the size of material tank in order to fully disperse the materials inside the tank and meet production process requirements.
