Pharmaceutical Grade 4000L Stainless Steel 1600-2400kg Ribbon Blender For Powder Mixing

Validated for regulated environments, this ribbon blender for powder mixing provides a 4000L stainless steel blending platform with a 1600-2400 kg batch for pharmaceutical and nutraceutical powders. The mirror-polished, crevice-free interior and GMP-oriented construction support easy cleaning and validation, while the gentle counter-flow ribbon action yields a uniform blend with minimal dust and no particle attrition. It is well suited to tableting and capsule-filling preparation, granules, and premix blending where batch integrity and traceability are essential.

The WLDH series ribbon mixer consists of a horizontal trough, a spiral agitating blade and a transmission unit. The spiral blade is generally made in two or three layers: the outer ribbon gathers material from both sides toward the centre, while the inner ribbon conveys it from the centre back to the two sides, so the two streams form a continuous convection mixing action. Because the trough can be manufactured with a circular section and fitted with a jacket, the same machine can also be used for reaction and drying when required. This unit is tuned to a 4000L trough and a 1600-2400 kg working batch, giving a compact, energy-efficient solution with a large loading coefficient.

• Double Ribbon Convection Principle: Counter-flowing inner and outer spiral ribbons lift material from the centre and fold it back along the trough walls, producing a fast, uniform blend without dead zones.
• Rapid, Gentle Mixing: Typical mixing time is only 3 to 8 minutes for a 1600-2400 kg batch, with a coefficient of variation (CV) that meets industrial uniformity requirements while protecting particle shape.
• Stainless Steel Construction: All material-contact parts are made of stainless steel with a smooth, crevice-free finish that resists corrosion, prevents cross-contamination and simplifies cleaning between recipes.
• Large Loading Coefficient: The horizontal trough design accepts a large fill ratio, so the machine reaches its rated capacity with a small footprint and low specific energy consumption per tonne.
• Easy Discharge and Maintenance: A durable discharge valve, generous inspection openings and a simple drive train make emptying, cleaning and routine servicing quick and straightforward.
• Flexible Process Integration: Optional jackets for heating, cooling or drying and a customized voltage (220V, 380V or 415V) let the machine fit a wide range of production lines.

The 4000L model supports pharmaceutical granule preparation, tableting and capsule-filling premixes, and nutraceutical powder blending under GMP-oriented conditions.

Thanks to its stainless steel contact parts and gentle convection action, this model is also suitable for mixing viscous or cohesive powders, for blending liquid and paste materials into dry powders, and for large-volume production where variety changes are infrequent. It is a reliable choice for food, pharmaceutical, nutraceutical, chemical, feed and new-material industries.

Changzhou Xiaoli Drying Equipment Co., Ltd. is a manufacturer of industrial drying, grinding, mixing, granulating and packaging machines applied in the food, pharmaceutical, nutraceutical and chemical industries.
