Introduction
The horizontal ribbon mixer is a highly efficient batch mixing equipment characterized by its unique double-ribbon design (inner and outer helical blades).
These counter-rotating blades move materials in opposing directions, creating intense cross-mixing that achieves high uniformity in just minutes.
It is renowned for its high mixing efficiency, large productivity, low energy consumption, and exceptional reliability.
Product introduction
The ribbon blender consists of a U-shaped horizontal trough, a double helical ribbon agitator, and a drive system. It is designed to achieve fast and uniform mixing of powders, granules, and low-viscosity materials.
Inside the mixing chamber, the inner and outer ribbons rotate simultaneously with the main shaft. The outer ribbon pushes materials from both ends toward the center, while the inner ribbon moves materials from the center toward both sides. This opposing flow creates a continuous convective mixing pattern.
In addition to axial movement, radial mixing and shear effects occur during operation, allowing materials to be repeatedly dispersed and recombined. This ensures a high level of mixing uniformity within a short processing time.
The discharge outlet is located at the bottom center of the trough. With the assistance of the outer ribbon, materials are efficiently pushed toward the outlet, enabling quick and complete discharge with minimal residue and no dead zones.
Machine details
Six component topics from the source listing, each shown with the matching equipment photograph.
01
Standard horizontal mixers are driven by gear reducers through direct connection, which has the advantages of high torque, high reliability, and low noise. For large-scale equipment, a combination of gear reducers and belt transmission is adopted to protect the transmission components in case of unexpected situations.
02
The ribbon main shaft is connected to the drive shaft flange, allowing for quick disassembly when maintenance or replacement of the shaft is required. The flexible disassembly design enables the U-shaped vessel to be fully welded to the two end plates, avoiding material gaps that may occur with large flange connections on the vessel and reducing residue.
03
Compared with other types of mixers, the horizontal ribbon mixer offers more flexibility in terms of the lid. It can be designed as fully open, half open, or fully sealed. The fully open design is suitable for situations that require high cleanliness standards and is supported by gas springs for convenient and safe operation.
04
Generally, a pneumatic flipper valve is adopted. The circular arc valve is tightly embedded in the cylinder, flush with the inner wall of the cylinder, and free from material accumulation and dead corners for mixing. The reliable edge strip-type sealing ensures no leakage during frequent opening and closing.
05
Various types of jackets can be added to the outer body of the mixer, allowing for cooling or heating of the material by injecting cold or hot media into the jackets. Cooling is typically achieved by pumping industrial water into the jackets, while heating can be achieved by introducing steam or thermal oil.
06
When mixing ultrafine powders, the use of a new type of balanced seal and packing seal enhances airtightness and effectively prevents the flow of gas and powder between the inside and outside of the vessel.

Complete line
Raw materials are fed into the system via a screw conveyor or vacuum feeder, then enter the ribbon blender for uniform mixing. After mixing, the finished product is discharged and transferred to the next stage through a conveying system, and finally packed by an automatic packaging machine. A dust collection system can be integrated to ensure a clean and safe working environment.
We engineer complete production solutions. A typical line from our portfolio includes:
Bulk bag dischargers, sack tip stations with dust control.
Vacuum conveyors, mechanical elevators matched to your layout.
