In the chemical, food, pharmaceutical and construction industries, combining a
screw conveyor with a ribbon mixer creates a seamless powder handling system for loading, blending and discharging. This screw conveyor and ribbon blender setup automatically transfers bulk powders, granules and additives into the horizontal ribbon mixer, then conveys the homogeneous mixture to downstream packaging or storage. It efficiently handles materials such as flour, seasonings, dry mortar, pigments, plastic compounds, nutritional powders and premixes, ensuring dust-free and labor-saving operation.
We understand processors prioritize dust containment, mixing uniformity, gentle material handling and easy cleaning. The screw conveyor is fully enclosed with dust-tight tubular casing and offers inclined or horizontal configurations to fit your floor layout. It provides steady, metered feeding from bags, silos or hoppers, preventing surges that compromise mix quality. The ribbon mixer features a double helical ribbon agitator inside a U-shaped trough, producing fast and thorough blending in 2 to 5 minutes with a high uniformity coefficient. Its large discharge gate enables complete emptying with minimal residual material. The entire contact area is crafted from SUS304 or SUS316L stainless steel with polished surfaces, meeting GMP and FDA hygienic standards. A quick-opening cleanout door and removable shaft seals allow fast washdown between batches, reducing cross-contamination in multi-product plants. The combined system can be designed with a pneumatically operated gate for automated transfer, plus optional liquid spray bars to add flavors, oils or binders during mixing.
Other advantages include heavy-duty gear drives, low energy consumption, safety interlock switches, and customizable ribbon designs (outer paddle, inner ribbon, or broken ribbon) for fragile or sticky materials. Optional cooling or heating jackets enable temperature-sensitive blending. Available capacities range from 50 liters to 30,000 liters, with the screw conveyor custom-sized to your required conveying distance and angle.
