The result is most intimate intermingling of all ingredients. The mixing time is depending on product characteristics, mixing accuracy and batch size | ||

Conical Double | Conical [[Double Shaft Mixers]] consists of driving part, screw agitator and reverse cone cylinder. The agitator are two asymmetrically helixes. They rotate around their own axes and revolve around the cone’s center axis at the same time with the help of the arm rotation effect. The material will be elevated repeated through the rotation and revolution of the helix and form shearing, convection and diffusing in the cone cylinder to realize perfect mixing effect. | ||
