Horizontal Ribbon Blender

Horizontal Ribbon Blender consists of a U-shaped horizontal vessel with a single or double helical ribbon agitator rotating within. The agitator shaft is located at the centre of the vessel. The shaft has support arms on to which the external and internal helical ribbons (spirals) are wound. The clearance between the external ribbon periphery and the internal wall of the mixing vessel is 3 to 6 mm depending on the application.

The ribbon blender is driven by an assembly of mechanical components comprising of a motor, gearbox and couplings. This type of blender can be operated in batch as well as continuous modes. It is primarily used for blending large volumes of dry solids, dry powder to wet phase mixing and for coating solid particles with small quantity of liquids to produce formulations.
