Ribbon Blender Manufacturer

Ribbon blenders are widely used for homogeneous mixing of dry granules & powders. The blender comprises a 'U' shaft with two sets of spiral ribbons, one inside the other. Inner and outer ribbons are perfectly arranged, that during rotation, the material reaches each corner of the trough and imparts radial & linear motion to the whole of the material to be mixed. Our range of ribbon blenders are based on a proven agitator construction that provides a triple mixing action ensuring fast, efficient blending.

Ribbon Blender Operations:

• The complete assembly is mounted on a MS/ SS structure
• The material is moved from side of the trough to the centre and vice versa resulting in quick & homogeneous mixing
• Double ribbon configuration also brings material towards central bottom outlet while discharging
• A specially designed valve is provided at the center or butterfly valve for discharge
• Blending is achieved in semi-fluidized state in the upper zone of the trough when used for fine powders
• Machine can be provided with spray nozzles with pressure spraying system for spraying additives in blenders
• Ribbon blender can also be used as dryer by providing jacket on the trough
• All contact parts in SS 304/ SS 316 quality
• Ribbon Blender Mixer comes in Standard and GMP models specially designed flush type outlet valve or butterfly valve (optional)
• Top cover with acrylic sheet

Ribbon Blender Working Principle

Ribbon blenders are made of shell having a U shape in which is rotating an agitator. The agitator is designed as a double helical ribbon which allows to create convective movement of the materials in 2 directions achieving mixing of powders and bulk solids. Ribbon mixers are very widespread in process industries for bulk solids dry Mixing. Although other Mixers designs exist which are over-performing ribbon blenders in some areas (mixing speed, hygienic design…), ribbon blenders are still a very simple and robust solution to mix dry materials offering decent mixing performances which are sufficient for many applications. It is not rare to have 40-50 years old industrial ribbon blenders in factories, still perfectly operational. Many manufacturers propose industrial ribbon blenders, from few hundreds liters to several cubic meters.
