◪Rotating Paddle
There are multiple stirring paddles inside vertical kneader, usually arranged vertically. These paddles are fixed on a shaft and rotated by a motor. The rotating motion of the stirring paddle generates strong stirring forcem pushing the material up and down along the barrel wall to achieve mixing and kneading of the material.
◪Shearing
The rotation of stirring paddle also generates shear forces between materials, causing relative sliding and deformation of the materials. This shearing action helps break the agglomeration structure of materials and promotes the mixing and exchange of materials.
◪Pushing Effect
The rotation of the stirring paddle also produces a pushing effect, pushing the material upward from the bottom of the barrel, and generating prossure between the paddle and the barrel wall, causing the material to be squeezed and folded, thus accelerating the mixing and kneading process.
◪Circular Motion
The rotation of the stirring paddle will also cause the material to circulate, allowing the material to be fully mixed and kneaded throughout the barrel. Typically the material rises along the barrel wall to the top, then drops along the central axis to the bottom, and so on until the desired degree of mixing is achieved.
