Ribbon Mixer Blender

Application & Process

Prism Ribbon Mixer Blender is used for uniformly dry mixing and blending applications in the pharmaceutical, chemical, cosmetic, food, pesticides, detergents, and plastics industries. The Ribbon Blender comprises of a U-shaped horizontal trough, specially designed Double Helical Ribbon Agitator, rigid fabricated structure motor, gear box.

In operation, material is filled to the top of the outer ribbon. The shaft rotates at relatively low speed and the moving ribbons push the material back and forth mixing it. The outer ribbon rotation displaces the material from the ends to the center while the inner ribbon rotations move the material from the center to the ends. This counter-current action results in homogenous blending. Mixing is achieved in 15 to 20 minutes with 90 to 95 % or better homogeneity. The bottom discharge provided for unloading of the material and easy cleaning of the mixing drum. Specially designed self adjusting sealing arrangement of unique design is provided to ensure that no black particle enters into the mixing drum.

Salient Features

• Design is cGMP - Current Good Manufacturing Practices compliance.
• All contact parts AISI S.S. 316/316L & non contact parts AISI S.S. 304.
• High mixing technology provides the ideal environment for effectively mixing a wide distribution of particle size and bulk densities without segregation.
• The shape of the container and mixing stirrer gives sufficient continuous movement to the powder/granules resulting in good quality. Minor ingredients are dispersed homogeneously without the need for pre-mixing.
• Double or triple action with blending occurring in the small voided areas immediately behind the blending ribbons.
• Minimal heat is generated due to internal friction & High particle movement.
• Fast, even liquid addition and coating by spraying system.
• Ideal for agglomerating and No over mixing.
• Direct drive gearbox with motor.

Safety Features

• Total drive transmission system enclosed.
• Limit switch installed in the top lid to ensure the lid is closed
• An air pressure switch is installed to ensure the pressure is within a limit.
• Limit switch installed at discharge to ensure product container underneath of discharge.
• Overload relay Protection and Emergency stop button.
