In short: For PVC dry blend and granule mixing with batch sizes of 100–6,000 kg, this horizontal ribbon mixer typically completes a uniform batch in 8–20 minutes, supports 304/316L stainless steel contact parts, and can be customized with heating/cooling, liquid addition, and PLC control.
PVC Plastic Granule Ribbon Mixer features a double-layer ribbon structure for rapid convection and material handling, ensuring uniform dispersion of PVC resin powder with stabilizers, lubricants, plasticizers, and other additives. Available in stainless steel and carbon steel, it offers a mixing time of 8–20 minutes per cycle for standard PVC dry blend, with optimized cycles down to 5–15 minutes for selected formulations and supports customization. Features include roller designs and discharge valves. Optional equipment includes a liquid addition system, pneumatic sampling device, nitrogen sealing protection, and PLC intelligent control. It supports 24-hour continuous operation and is suitable for industrial-grade production.
The PVC Plastic Granule Ribbon Mixer employs a double-layer spiral ribbon structure, ensuring fast mixing speed and high uniformity. It prevents material breakage, clumping, and segregation when mixing PVC granules, powders, additives, and masterbatches, guaranteeing stable batching. The equipment boasts a robust structure, excellent sealing, and stable operation, effectively reducing dust and raw material loss. Customization is supported, allowing for flexible design based on production volume, material properties, heating and cooling requirements, and frequency conversion speed regulation. It can also be integrated with feeding, metering, and packaging equipment to form automated production lines, adaptable to various plastic processing techniques.In internal dry-blend trials with PVC resin (bulk density approx. 1.4 g/cm³, 65% fill level), the unit achieved a uniformity variation of ≤2% after 8 minutes. Actual results vary by formula, particle size, and additive ratio. Test reports are available on request.
The PVC plastic granule belt mixer uses a motor-driven transmission device to rotate the double-layer spiral ribbon inside the drum. The inner spiral ribbon pushes the material to one side, while the outer spiral ribbon transports it to the other, creating strong convection and circulation within the drum for the PVC raw materials, including granules, powders, additives, and masterbatches. The PVC plastic granules rapidly diffuse and mix in a short time, achieving a uniform proportion.

The PVC Plastic Granule Ribbon Mixer mainly consists of five parts: a mixing cylinder, a stirring device, a drive system, and a control system. The mixing cylinder has a horizontal U-shaped structure, with an outer semi-pipe or jacketed structure for circulating heat transfer oil/steam for heating. The stirring device is the core component, consisting of a main shaft and double-layer counter-directional spiral ribbons. The gap between the inner and outer spiral ribbons and the cylinder wall is precisely controlled at 2-5mm to ensure thorough mixing. The drive system is equipped with a variable frequency motor and a heavy-duty reducer, with stepless speed adjustment between 20-60 rpm to adapt to different material characteristics. The control system integrates a PLC touch screen, capable of storing 50 sets of formula parameters, and features over-temperature alarm, overload protection, and data traceability functions. A pneumatic flap discharge valve is installed at the bottom for rapid unloading within 5 seconds.For heat-sensitive PVC, jacket cooling is recommended, and all product-contact parts can be mirror-polished 304 or 316L stainless steel.
A PVC pipe and profile manufacturer in Germany with annual output of 20,000+ tons used a 500L PVC Plastic Granule Ribbon Mixer for dry blend and color masterbatch mixing. Before installation, they faced color difference ΔE > 2.5, batch CV > 6%, and frequent material buildup. After switching to the 500L double-ribbon mixer with a pneumatic flap discharge valve, they achieved CV ≤ 3%, ΔE ≤ 1.5, mixing time reduced from 20 min to 10 min, and production capacity increased by over 30%. The customer reported: “The ribbon mixer eliminated color streaks and reduced cleaning downtime.”
Reference benchmark: WAM WBN industrial ribbon blenders achieve 5–15 min mixing times for dry PVC. Dahan’s patented double-ribbon design achieves CV≤5% in 3–15 minutes.
The material selection for a PVC Plastic Granule Ribbon Mixer requires comprehensive consideration of material characteristics, process temperature, and hygiene requirements. The core principle is to prioritize stainless steel for contact parts. For the mixing cylinder, screw conveyor, and discharge valve that come into direct contact with the materials, 304 or 316L stainless steel is recommended. All stainless steel inner walls must be mirror-polished to prevent material adhesion and residue. If the mixing process involves high temperatures, it is recommended to thicken the inner wall to 6-8mm and use heat-resistant alloy steel. The final material selection needs to be verified through specific formula testing to ensure a balance between corrosion resistance and economy. You can also tell us the characteristics of your materials, and we will customize a suitable mixing material for you.
For heat-sensitive PVC, avoid excessive shear and keep the jacket temperature below 110°C for rigid PVC or 90°C for flexible PVC, depending on plasticizer content. The batch temperature should never exceed 120°C — above this threshold, PVC begins to dehydrochlorinate, releasing HCl and causing yellowing or “burnt batch” defects. 304 stainless steel with mirror polish is usually sufficient for standard PVC dry blends; 316L is recommended for corrosive additives (e.g., flame retardants, antistatic agents, or chloride-containing stabilizers) or high-humidity environments, as molybdenum content in 316L significantly improves resistance to pitting and crevice corrosion.
The PVC Plastic Granule Ribbon Mixer can be integrated with feeding machines, screening machines, packaging machines, etc., to form an automated, continuous PVC batching and mixing production line, improving production efficiency. It can also be used with screw conveyors or vacuum conveyors to automatically transport PVC granules, powders, additives, and other raw materials, eliminating the need for manual feeding and reducing dust pollution and labor intensity. Before mixing, a screening machine can be connected to pre-treat materials with lumps, impurities, or uneven particle size, ensuring the purity of the feed and improving mixing accuracy and finished product stability. After mixing, it can be directly connected to a metering and packaging machine to achieve integrated quantitative filling, sealing, and packaging operations, reducing material transfer, residue, and secondary contamination. The entire production line has a reasonable layout, is easy to operate, and runs stably. It can be flexibly combined according to actual production capacity and process requirements, and is widely applicable to PVC granulation, pipe, profile, sheet, and recycled plastic processing scenarios, effectively improving the automation level and economic benefits of enterprises.

A ribbon mixer uses inner and outer helical ribbons to create a fluidizing, convective mixing action, which is excellent for blending powders and granules with minimal shear. A paddle mixer uses blades that cut through the material, providing more aggressive mixing, but can generate more heat. For heat-sensitive PVC granules, the gentle action of a ribbon mixer is often preferred.
Yes, our ribbon mixer is specifically designed for bulk solids. It is highly effective at blending powders, granules, and even flakes with densities up to 1.5 g/cm³. The spiral ribbons create a uniform mix regardless of particle size or shape variations.
