LODHA Ribbon Blender

Ribbon Blender Model LI-RB is compact model used widely in pharmaceutical, nutraceutical, cosmetic, chemical and food industry. It is a light duty, compact blender is specially designed to achieve convention mechanism of blending powder components which are pre–processed like dried granules, pre-sieved powders etc. It is low shear mixer and ideal for solid/ solid mixing and solid/ liquid mixing can also be achieved when high shearing force is not desired. It occupies less head room space for large volume mixing unlike Double Cone, ‘V’ Blenders etc

Powder blenders from LODHA include Ribbon & Paddle designs and range in capacity from 1/2 cu ft. laboratory models to 1000 cu. ft. production units. A wide variety of horsepower and speed combinations satisfy the most demanding blending applications. Optional features such as sanitary designs, vacuum construction, special valves and cover openings can be provided to fine tune the machine to your process

Agitators

The agitator is the most important component of the mixer, and we offer several options:

Double Ribbon Multi-Pitch Double Ribbon Standard Paddle Trowel

 All agitator types have at least one thing in common; the outer ribbon/paddle conveys material towards the discharge and the inner ribbon/paddle conveys material away from the discharge.

Special features:

Available in two shapes – U & W. U-for Low to Medium Volume Capacity (single shaft). W-for Large to Mega Volume Capacity (double shaft). Batch size based on 65% of Blender volume. All contact parts in stainless steel 304. Bearing mounted on lanterns out of mixing zone to avoid Cross contamination. Feeding through a charging port mounted on top of the blender. Reduced Material handling due to side discharge facility of processed materials. Monoblock Design avoids Cross Contamination Meets all cGMP / cGMP standards Air purge on the side entry seals for better cross contamination control Continuous Ribbon design for complete discharge of the finished product. Variable frequency drive for fine tuning the Shear energy at different stages of Blending Belt driven power transmission for Quieter environment and less maintenance. Reduced material handling with Top mounted charging port and Side discharge arrangement for Total containment. Bearing mounted on the lanterns outside the Mixing zone to avoid Cross contamination. Paddle style agitator instead of Ribbon for Blending fragile materials. Capacity available 20 Kg to 2500 Kg

 

Process Operation:

Ribbon Blender (Ribbon Mixer) is a basic industrial mixing blender. They consist, basically, of a trough-shaped shell (usually 2 to 3 times longer than it is wide) with a semi-circular bottom, fitted with a horizontal longitudinal shaft on which are mounted arms supporting a combination of ribbon blades, paddles or helical screws set at a fairly close clearance to the semi-circular mixer body so that no layer of material remains on the bottom of the ribbon mixer. The most effective design of ribbon layout is the double spiral in which the outer ribbon moves the product in one direction and the inner ribbon moves it in the opposite direction.

The ribbons rotate and move materials both radially and laterally to insure thorough blends in short cycle times. Ribbon agitators are used for blends that will be between 40 and 70% of the rated capacity of ribbon blender.

 

Applications:

The ribbon blender’s versatility for blending solids combined with its ability to perform heating, cooling, coating, and other processes make it a very popular mixer.
