Double Ribbon Mixer

The double ribbon mixer is suitable for industries such as food processing, chemicals, agriculture, and pharmaceuticals. It is designed for mixing powders, small granules, and various other materials. During operation, the inner ribbon conveys the material outward, while the outer ribbon pushes the material inward, enabling rapid convective mixing and achieving excellent homogeneity within a short time. It features strong mixing uniformity, high production efficiency, and an extremely low failure rate.

Product Introduction

The double ribbon mixer is suitable for industries such as food processing, chemicals, agriculture, and pharmaceuticals. It is designed for mixing powders, small granules, and various other materials. During operation, the inner ribbon conveys the material outward, while the outer ribbon pushes the material inward, enabling rapid convective mixing and achieving excellent homogeneity within a short time. It features strong mixing uniformity, high production efficiency, and an extremely low failure rate.

Equipment Advantages

• Wide application range: suitable for solid–solid (powder–powder), solid–liquid (powder–liquid), and liquid–liquid mixing.
• High mixing uniformity: capable of achieving homogeneous blending at ratios up to 1:10,000, demonstrating particular advantages when mixing materials with significant differences in bulk density.
• Fast mixing speed and high efficiency: 6–10 times more efficient than conventional mixers, or even higher in certain applications.
• Rapid and convenient discharge: typically completes discharge of one batch within 2–5 minutes.
• Gentle mixing process: preserves the original physical properties of materials with minimal degradation.
• No material contamination: the stirring assembly is integrally constructed, ensuring safety and reliability. All corners and weld seams are smoothly finished for easy cleaning. Lubrication points are located outside the main chamber, preventing oil leakage or wear debris from entering the material. The system can operate in a sealed condition to prevent airborne dust contamination.
• Low energy consumption with a high loading coefficient.
• Minimal plant requirements: horizontal configuration with flexible drive and discharge position options; not restricted by building height and occupies relatively small floor space.
• Stable and reliable operation, few wearing parts, long service life, easy maintenance, and simple operation.

Factory Inspection of the Double Ribbon Mixer

Each mixer must be inspected and approved by the manufacturer’s quality inspection department and accompanied by a certificate of conformity before delivery.

Prior to shipment, each mixer shall undergo a 30-minute no-load test at rated speed and meet the following requirements:

• Stable and normal operation without abnormal noise; control mechanisms must be flexible and reliable.
• No loosening of connections or fasteners.
• For mass-produced units, at least two mixers per year shall be randomly inspected and tested in accordance with JB/T 9820.3, and the results shall comply with Clause 3.4.
• Upon delivery, the purchaser shall inspect and accept the product according to this standard. If the product fails to meet requirements, the manufacturer shall repair and resubmit it for acceptance. Under the condition that the user operates the mixer in accordance with the manufacturer’s instruction manual, the manufacturer shall provide repair, replacement, or return within one year from the date of purchase if damage is caused by manufacturing defects.
• The quality of the paint coating shall be inspected in accordance with JB/T 5673.

Widely used in pesticides, veterinary drugs, food products, chemicals, biotechnology, aquaculture, ceramics, refractory materials, plastics, compound fertilizers, and other industries for solid–solid (powder–powder) and solid–slurry (powder–paste) mixing. It is particularly suitable for blending viscous materials.
