Horizontal ribbon blender with counter-flow double helical ribbons for convective batch blending of polymer pellets, powders, regrind, and masterbatch without frictional heat build-up.
Reference values for the model or models named above. The confirmed configuration, the capacity basis and the scope of supply are stated in the quotation and the drawings.
Overview
Blends polymer pellets, powders, regrind, masterbatch, and functional additives into a uniform, homogeneous batch before extrusion or compounding.
A horizontal ribbon mixer (ribbon blender) delivers convective, multi-directional batch mixing for plastic compounding, masterbatch manufacturing, and polymer recycling lines. Engineered with double-helical counter-flow ribbons, it conveys outer material toward the center while the inner ribbon pushes inner material outward, creating continuous fluidization, rapid axial folding, and thorough cross-blending.
Unlike high-shear vertical mixers that generate rapid frictional heat, the horizontal ribbon blender operates at gentle-to-medium shear speeds. This makes it an ideal mixing solution for temperature-sensitive compounds, soft elastomers (such as TPE, TPU, and EVA), pellets pre-blended with functional additives, and dry powders with divergent bulk densities—effectively preventing material melting, agglomeration, and batch segregation.
Key features
Each picture names one part of the machine and what it does for the material and the batch.
Inner and outer continuous helical flights mounted on a heavy-duty center shaft. The outer ribbon conveys ingredients toward the central discharge, while the inner ribbon sweeps material outward to the endplates, creating high-efficiency fluidization, counter-current convection, and rapid axial dispersion without shearing polymer chains.
One-piece U-shaped vessel fabricated with continuous inner welds ground smooth to Ra ≤ 0.8 µm. Precision ribbon-to-wall radial clearances minimize stagnant unmixed pockets, ensuring consistent batch homogeneity and rapid cleanability during color and formulation changeovers.
The outlet is set at the centre of the trough with the opening contoured to the trough radius, so no ledge is left for material to rest on. The spout is flanged to suit the container or conveyor you discharge into, and the discharge clearance is confirmed against the bin, IBC or mobile container actually used on site. The gate is hand-operated on the standard build and available pneumatically where the line needs faster emptying.
Top cover features sealed pneumatic gas-spring assist inspection hatches protected by safety interlock limit switches. The blender automatically cuts drive power instantly when covers open, ensuring complete operator safety during cleaning, inspection, and maintenance.
Prepared for Screw-Conveyor Charging The top cover inlet is flanged and positioned so a screw conveyor or screw feeder can be connected directly, and the inlet size is confirmed against the conveyor finally chosen for the line. The blender itself is supplied ready for that connection rather than with a fabricated hopper.
Material and process
Read the conditions together: a machine is selected for the material and the output, not from its name alone.
Optimized for free-flowing polymer pellets, virgin resins, recycled regrind flakes, color and additive masterbatches, and mineral powders (such as calcium carbonate, talc, barium sulfate, and flame retardants). The dual counter-flow ribbon geometry ensures rapid, convective macro-mixing across divergent bulk densities (0.25 to 1.6 kg/L) and particle diameters (20 µm powders up to 10 mm flakes/pellets).
Particularly suited for formulations sensitive to friction-induced temperature rise, including soft elastomers (TPE, TPU, TPV, EVA), PVC dry-blends, hot-melt adhesives, and engineering plastics pre-compounded with lubricants or liquid bonding agents. Batch working capacities range from 300 liters to 3,000 liters per cycle.
Convective solid-solid batch mixer and homogenizer; not a high-intensity disperser or plasticizing reactor. Operating boundaries include:
Accepts free-flowing virgin polymer pellets, post-consumer / post-industrial regrind flakes, masterbatch granules, micronized additives, and mineral powders (CaCO3, talc, flame retardants, stabilizers). Charging can be performed via top manual bag-dump stations with integrated dust filtration hoods, flexible bulk bag (FIBC) unloaders, or pneumatic conveying vacuum receivers.
Input raw ingredients must be free of metallic tramp contamination, oversized agglomerates exceeding ribbon clearances, and free-standing moisture that could cause severe powder cake formation inside the trough.
Delivers a uniformly distributed, homogeneous dry batch with minimal particle attrition and no thermal degradation. Discharges via the bottom central gate directly into mobile transfer bins, intermediate bulk containers (IBCs), pneumatic dense/dilute phase conveying pick-up adapters, or surge hoppers positioned above loss-in-weight compounding extruders.
Clean batch discharge is achieved within 60 to 180 seconds, leaving negligible residual holdup in the bottom trough.
Throughput
Read a figure together with the basis below it: the same machine reaches different numbers on different materials.
300–10000 L (batch working volume)
Figures denote the effective working volume (typically 40% to 70% of the total trough volume) required for optimal cross-flow fluidization and turnover. Usable batch weight depends on material bulk density, component proportions, and flow characteristics. Highly filled powders fill the working volume at different mass loadings than light virgin pellets or regrind flakes.
Models
The figures are the reference values entered for each model. The model for your line is confirmed against your material and output before it is quoted.
Delivered a 1,000L working capacity horizontal ribbon blender for an additive compounding facility. Configured with mirror-polished SUS304 contact surfaces and an air-purged bottom discharge gate, the unit delivers gentle, convective macro-mixing of fragile pellets and pigment powders within 4–6 minutes without frictional melting.
Supplied an array of multi-ton horizontal ribbon blenders for a large-scale engineering plastics compounding workshop. Operating in continuous batch rotation, the units feed multiple twin-screw extrusion lines, ensuring consistent bulk density and zero lot-to-lot color deviation across high-capacity compounding operations.
Engineered and commissioned a heavy-duty 3,000L ribbon blender installed on an elevated mezzanine platform for a post-consumer plastics recycling plant. Equipped with reinforced helical ribbons and pneumatic vacuum loading interfaces, the system thoroughly homogenizes recycled flakes across divergent bulk densities (0.3–0.9 kg/L) before extrusion.

Scope of supply
The quotation states the scope for the confirmed configuration; the groups below describe how a supply is normally split.
Installation planning
These are the connections the machine and the line around it have to agree on before the layout is fixed.
Mechanical: Bolted baseplates anchored to a level foundation floor or elevated mezzanine steel structure; standard round/square flanged charging ports (DN200–DN300) and central bottom discharge flange (DN150–DN250) compatible with slide valves, butterfly valves, or flexible bellows.
Electrical & Automation: Three-phase main power connection to the IP54/IP55 floor-standing or machine-mounted control cabinet. Control terminals provide dry potential-free contacts for remote Run/Stop status, cycle completion, safety interlock trips, and handshake interlocks with upstream feeding systems and downstream buffer receivers.
The buyer provides a reinforced level concrete floor engineered for static and dynamic machine operating loads, unhindered access corridors for cleaning and shaft/bearing maintenance, and main power supply terminated at the local electrical control panel. Upstream charging infrastructure (overhead hoists, big-bag discharge frames, or pneumatic receiver mounts) and downstream discharge hoppers/surge bins are coordinated to the agreed machine centerline dimensions.
Selection
Work through what you already know. The rest is settled in the conversation, not before the first message.
Blender selection should be based on effective working volume, bulk density, and target batch cycle time rather than gross trough volume alone:
