WLDH Horizontal Ribbon Mixer Stainless Steel Double Ribbon Powder Blending Machine

The WLDH horizontal ribbon mixer is the flagship mixing machine of our ribbon series, engineered for fast, uniform blending of powders, granules and other dry materials. Its horizontal trough and counter-flowing inner and outer ribbons fold the material continuously to form a convection mix, producing a homogeneous blend in only a few minutes. Available from 100L to 10000L, the WLDH series covers laboratory, pilot and full production scales with a single, proven design. Stainless steel contact parts, optional jackets for heating, cooling or drying, and customized voltage make it adaptable across the chemical, food, pharmaceutical, feed and new-material industries.

Every WLDH 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.

• Proven WLDH Series Design: A mature, field-tested platform covering eleven standard sizes, so spare parts, service experience and performance data are consistent across the whole range.
• Double Ribbon Convection Mixing: Inner and outer ribbons move material in opposite directions, eliminating dead zones and reaching uniformity in a single short cycle.
• Full Range 100L to 10000L: One design language from laboratory trials to bulk production means recipes scale up with predictable results.
• Stainless Steel Construction: Smooth, crevice-free stainless steel contact parts resist corrosion, meet GMP-oriented hygiene needs and simplify cleaning.
• Flexible Integration: Optional heating, cooling or drying jackets, pneumatic or manual discharge, and customized voltage let the mixer drop into existing lines.
• Low Specific Energy: The horizontal trough accepts a large fill ratio, so high throughput is achieved with modest power consumption per tonne.

The WLDH horizontal ribbon mixer is used across food, pharmaceutical, nutraceutical, chemical, feed and new-material production. Typical duties include spice and seasoning blends, milk and cocoa powders, nutritional premixes, detergent powders, pigments, fillers and general dry chemical compounds, in batch sizes from pilot to bulk.

All models share stainless steel contact parts and a gentle convection action, so they are equally suited to viscous or cohesive powders and to blending liquid and paste materials into dry powders. The WLDH range 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.

We offer full customization of capacity, voltage, jacket and discharge type, together with documentation and spare parts support. Our engineers are glad to advise on the correct WLDH model, recommend the optimal fill level and mixing time, and provide layout drawings for your production line before shipment.

• What is a WLDH horizontal ribbon mixer? It is a horizontal-trough blender in which inner and outer spiral ribbons move material in opposite directions to create a convection mix. The WLDH designation refers to this ribbon-mixer series.
• Which sizes does the WLDH series include? The standard range runs from WLDH-0.1 at 100L up to WLDH-10 at 10000L, with working capacities from 30-50 kg to 4000-6000 kg per batch.
• How uniform is the mix? A typical batch reaches a coefficient of variation that satisfies common industrial uniformity standards within 3 to 8 minutes.
• Can it be heated, cooled or dried? Yes. An optional jacket allows reaction, heating, cooling or drying, so a single machine can cover several process steps.
• What are the MOQ, delivery and warranty terms? The MOQ is 1 set, delivery is normally about 30 working days, and every machine carries a 12-month warranty with technical support.
