Shear Bar Mixers
Shear Bar Mixers are highly versatile and mostly used for manufacturing toothpaste, creams, cosmetics and viscous products.
The process in this mixer is similar with Contra Rotating Mixers.
The mixing assembly consists of series of paddle type blades of appropriate shape to move the material back towards the center of the container. The paddle type blades are provided on the central shaft which runs through a hollow shaft on which other sets of blades are welded. Both the sets of blades intermeshed with each them and rotates in clockwise and anti-clockwise direction respectively and one sets also scraps the container wall for thorough and uniform mixing of the material. The mixer is so designed to withstand high vacuum applied in the process for optimum mixing.
