Compact 100L Horizontal Ribbon Mixer Machine Stainless Steel 30-50kg Batch Powder Blender

Engineered for research laboratories, pilot plants and small-batch production lines, this WLDH horizontal ribbon mixer delivers precise, reproducible blending of small powder and granule volumes. Its compact stainless steel trough fits easily on a bench or in a confined workshop while still applying the same double-ribbon convection principle used in full-scale industrial mixers. The gentle yet thorough ribbon action prevents segregation of fine powders and keeps particle size intact, making it an ideal choice for cosmetic, pharmaceutical and food R&D teams that need fast batch turnaround and easy cleaning between formulas.

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 100L trough and a 30-50 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 30-50 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 100L model suits laboratory R&D, small-batch cosmetics, pharmaceutical trials and food development where repeated small formulas must be blended quickly and cleaned easily.

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. Established in 2014 and exporting more than 80% of its output to overseas markets, the company designs every machine around the principle of building touching products with the spirit of craftsmen. With in-house engineering, strict quality control and responsive after-sales service, our team helps customers select, install and maintain the right ribbon mixer for their process.
