Paddle Mixers
Paddle Mixers Overview
Paddle Mixers are versatile horizontal batch mixers designed for gentle yet thorough mixing of powders, granules, and pastes. The mixer consists of a cylindrical horizontal vessel with one or more central shafts equipped with angled paddles. The paddle agitators create axial and radial movement of the material, promoting efficient mixing with low shear, making it suitable for fragile or heat-sensitive materials. These mixers are widely used in pharmaceuticals, food processing, chemicals, and other industries requiring uniform blending of bulk solids.
Working Principle
The paddle mixer operates by rotating paddles that push and lift the material, producing a mixing flow that is both axial (along the length of the vessel) and radial (from the center to vessel walls). This motion ensures that all particles are uniformly distributed within the batch without breaking down delicate particles or generating excessive heat. The slow to medium speed ensures gentle blending while avoiding segregation.
