Used ROSS 5 Cubic Foot Double Ribbon Mixer – 316 Stainless Steel, 5 HP Motor

The ROSS Model RB42N Double Ribbon Mixer is a versatile and widely used piece of industrial mixing equipment. It is specifically designed to blend dry powders, granules, and pastes uniformly and efficiently. The double ribbon design ensures thorough mixing and is well-suited for a wide range of industries, including pharmaceuticals, food processing, chemicals, and more.

Here’s a breakdown of the key information and features for the ROSS Model RB42N Double Ribbon Mixer:

Key Features:

1. Capacity:

   • 5 Cubic Feet (approximately 142 liters).
   • This size allows for mixing moderate quantities, making it suitable for both batch processing and pilot-scale operations.

2. Ribbon Mixing Action:

   • The double ribbon design features an inner and outer ribbon that work together to move material in opposing directions. This creates a balanced and consistent mixing action.
   • The inner ribbon moves material from the center to the outside, while the outer ribbon moves material from the outside to the center, ensuring uniform mixing of all particles.

3. Construction:

   • Material: The mixer is typically constructed from high-quality stainless steel (often indicated by the "SS" in the model number), which ensures durability, corrosion resistance, and easy cleaning.
   • Finish: The surface is often polished to minimize contamination and facilitate ease of cleaning, especially in industries like pharmaceuticals and food processing.

4. Versatility:

   • Suitable for dry powder blending and can also handle slightly moist materials, granules, or even pastes in certain applications.
   • The mixer can handle a wide range of ingredients, from fine powders to coarser materials.

5. Drive and Motor:

   • The unit is typically powered by an electric motor, which drives the ribbon mechanism. The specific motor power will depend on the size and model but is usually designed for continuous, efficient operation.

6. Discharge Mechanism:

   • Most models come with a bottom discharge outlet that ensures smooth and controlled discharge of materials after mixing.
   • The discharge valve or door can be manually or pneumatically operated, depending on the model.

7. Operation:

   • The mixing process is simple and involves loading materials into the drum, starting the mixer, and allowing the ribbons to move the materials into a homogeneous blend.
   • The design ensures minimal product degradation while providing uniform consistency.

8. Customization:

   • The mixer may offer options for variable speed control, which allows adjustment of the mixing speed based on the material being processed.
   • Additional features such as heating/cooling jackets or integrated vacuum may be available for more specialized applications (e.g., drying or removing moisture).

9. Applications:

   • As noted, the RB42N is commonly used in industries such as food, pharmaceuticals, chemicals, and cosmetics for blending dry powders, granules, or pastes.
   • It can also be used for blending ingredients for various formulations like tablets, granules, detergents, animal feed, and more.

10. Safety Features:

• Built-in safety features such as overload protection, emergency stop buttons, and guarding are typically included to ensure safe operation in an industrial environment.

Typical Applications:

• Pharmaceuticals: Mixing APIs and excipients for tablet or capsule formulations.
• Food & Beverage: Blending powdered ingredients for snack foods, seasonings, or powdered drink mixes.
• Chemicals: Mixing dry chemicals or pigments for paints, coatings, or other chemical formulations.
• Cosmetics: Uniform blending of ingredients for creams, lotions, or powders.
• Animal Feed: Homogeneous mixing of vitamins, minerals, and other feed components.

Advantages:

• High Mixing Efficiency: The double ribbon configuration ensures that the materials are thoroughly mixed with minimal energy input.
• Gentle Mixing: It is suitable for both fine and coarse powders and is less likely to cause degradation of the materials during blending.
• Uniformity: The design helps achieve a very consistent end product.
• Ease of Cleaning: Stainless steel construction and smooth surfaces make cleaning easy, which is critical in regulated industries like pharmaceuticals and food processing.

Specifications:

• Model: RB42N
• Capacity: 5 cubic feet (approx. 142 liters)
• Material of Construction: Stainless Steel (SS)
• Discharge Type: Bottom discharge (manual or pneumatic)
• Mixing Type: Double Ribbon
• Drive: Electric motor (varied depending on model size)
