	Example:		==Example==
	Conical Double Screws Mixer (also called [[Nauta 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.

	==Applications==		==Applications==

	Vertical ribbon blenders are generally used in case of applications that require gentle mixing action and minimal heat generation at the same time these mixers can also be used for applications that requires high shear mixing this is accomplished using lump breakers, which is driven separately.
