Ribbon Blender (mixer)

How the Ribbon Blender (mixer) Works

A Ribbon Blender machine consists of a horizontal trough with a central shaft and a helical ribbon agitator. Mixing results from the turbulence induced by counteracting Ribbons. There are two sets of Counter acting Ribbons - Outer Ribbon, Inner Ribbon. Both ribbons mounted on the same shaft. Ribbons has close Trough clearance which provides a region of high shear force near the wall thereby achieving both bulk blending and dispersive mixing.

Ribbons are design to obtain complete and thorough mixing. Ribbon Blender mixer is designed in such a way that along with vertical movement, material to be mixed will have to and fro motion. Diametric size of the ribbon keeps some proportion with the volume of the vessel so that the power required to drive the machine will be less. The ribbon causes all the material to circulate using only 5% of the power needed by the turbine.

When the economy of the mixing equipments are taken into consideration the ribbon blender is the best suited machine for better result in the field of chemical, pharmaceutical and allied industries.

The Ribbon machine is manufactured in the combination of Mild Steel and Stainless Steel. The product to machine contact parts will be in Stainless Steel and remaining is in Mild Steel to reduce the total cost of the machine. cGMP models are also available.

Special Features of Ribbon Blender (Mixer) Machine

• Ribbon cross-section and pitch, close clearances between outer ribbon and shell, and number of spirals on the ribbon are the few features which can be varied to accommodate materials ranging from low-density finely divided materials to fibrous and sticky materials
• The Ribbon Blender is adaptable to batch or continuous mixing.
• HEATING or COOLING JACKET as per process requirements.
• CHOPPERS - Choppers can be provided as a Delumper or as a Fine Grinder.
• Hinged Cover, Dependable Discharge Outlet.- Manual lever or hand wheel operated slide gate valve, swing-type flush mounting plug valve
• Discharge - Hand wheel operated slide gate valve, gates, drop bottom, seals and finishes
• The PADDLE design is optional and normally applied where FRIABLE materials are being blended and when batches as small as 15% of the total capacity are going to be mixed in one blender.
• Optional Scale hoppers are available
• Constructed of SS 316, SS 304 and Carbon Steel.
• Capacity - 25 Ltr. to 7,500 Ltr.
• Fast, Easy Cleaning - The entire ribbon assembly is removable as a unit.
• Shaft Seal - Three rows of packing, of type compatible with product and application, housed in a standard gland follower stuffing box, assist in keeping dirt out and product in. Purged and lubricated seals as well as the mechanical seals are also available.
• Simplified Drives - Typically units of sizes to 100 cu. ft (2.8 cu. m) and 15 H.P. drive are driven by a torque arm reducer with "V" belts and an integrally mounted motor.
