What Is a Horizontal Ribbon Mixer?
A Mélangeur à ruban horizontal is a mixing machine that uses a horizontal U-shaped chamber and ribbon mixing structure. It is also a type of powder mixing equipment commonly used for blending powders, granules and formulations.During operation, the rotating ribbons drive materials to circulate inside the chamber, allowing different components to fully contact each other.The core of the equipment is the axial circulation movement created by the double ribbon structure, which enables continuous exchange between materials near the chamber wall and those in the center.
The Horizontal Ribbon Mixer is mainly used for mixing multiple powder materials, granules and formulations requiring small amounts of liquid addition. Since different materials vary in flowability, density, viscosity and mixing requirements, the appropriate ribbon structure, equipment specification and auxiliary configuration need to be selected according to specific production conditions.
Principe de fonctionnement
The mixing process mainly relies on the circulation movement created by the double ribbon mixing system. The motor drives the ribbon shaft through the reducer, causing materials inside the chamber to circulate throughout the mixing cycle and achieve uniform mixing through material movement and exchange.
Power Transmission:The motor drives the ribbon shaft to rotate and provides power for material circulation. The reducer maintains a stable rotation speed, allowing the mixer to handle different material loads and achieve consistent mixing performance.
Two-Way Circulation:The outer ribbon is installed close to the chamber wall and mainly pushes materials from both sides toward the center. The inner ribbon moves materials from the center area toward both sides. The inner and outer ribbons work together to create continuous circulation and material exchange inside the chamber.
Mixing Process:As the ribbons rotate, materials are continuously moved, turned over and redistributed inside the chamber. Different raw materials achieve sufficient contact, allowing powders, granules and multi-component formulations to achieve uniform mixing.
Main Structure
The structure of the Horizontal Ribbon Mixer is mainly designed around material circulation and stable operation. The mixing chamber, ribbon agitator assembly and transmission system all affect the mixing performance and operating conditions.
U-Shaped Mixing Chamber：The U-shaped chamber is the main space for material mixing. Its internal structure needs to ensure that materials can move with the ribbons. The chamber size and effective volume are generally designed according to the batch capacity to avoid excessive loading from affecting material circulation.
Ribbon Agitator Assembly：The ribbon agitator assembly is the core component responsible for mixing. It consists of a main shaft and inner and outer ribbons. The inner and outer ribbons adopt different directional designs to move materials in different areas and create circulation inside the chamber. For different materials, suitable ribbon structures and operating parameters need to be selected.
Transmission System：The transmission system consists of a motor and reducer, providing stable power for ribbon rotation. The power configuration needs to be selected according to equipment specifications and material loads to ensure stable operation of the mixing system.
Discharge Device：The discharge device is located at the bottom of the chamber and is used to discharge the mixed materials. A reasonable discharge design can reduce material residue and facilitate connection with downstream équipement de convoyage and packaging equipment.
For different materials and production requirements, the chamber size, ribbon structure and drive configuration need to be properly matched. Otherwise, insufficient material circulation or uneven mixing may occur.
Application Materials
The Horizontal Ribbon Mixer is suitable for mixing powders, granules and formulations containing small amounts of liquid. Different materials vary in flowability, particle size, density and formulation requirements. Therefore, equipment selection should not only consider machine size, but also whether materials can exchange sufficiently during mixing and whether problems such as particle breakage or uneven liquid distribution may occur.

If materials have high moisture content, strong viscosity or large differences in component ratios, it is recommended to provide material information in advance so that engineers can confirm the appropriate ribbon structure and equipment configuration.
How to Select
When selecting a Ribbon Mixer, do not consider only the model size. We usually first understand the material characteristics, required batch quantity, and whether special requirements such as liquid addition or heating are involved. Using the same configuration for different materials may result in different mixing performance.
1.Powder Mixing:For flour, food additives, chemical powders and other powder materials, focus on material flowability and batch loading quantity. Equipment that is too small may not provide sufficient space for material circulation, while equipment that is too large may reduce equipment utilization.
2.Powder and Granule Mixing:For plastic pellets, resin granules, feed pellets and other materials, attention should be paid to maintaining particle integrity during mixing. In addition to capacity, the ribbon structure and operating speed should be considered to avoid affecting particle condition.
3.Formulations with Liquid Additives:If oil, additives or other liquid components need to be added during mixing, the liquid addition amount and method should be confirmed in advance. Uniform liquid distribution directly affects the final mixing result.
4.Mixing Quantity and Equipment Specification:Equipment size mainly depends on the batch mixing quantity, while material density, mixing time and production requirements also need to be considered. Accurate material information allows engineers to determine a more suitable equipment specification.

Jiarui Manufacturing
Although the structure of a Horizontal Ribbon Mixer is straightforward, the actual mixing performance mainly depends on the internal mixing system. The ribbons need to circulate and exchange materials inside the chamber during mixing. If the matching between the ribbons and the chamber is not properly designed, material circulation may be affected and uneven mixing may occur.
During manufacturing, Jiarui focuses on the matching between the mixing shaft, ribbons and chamber. The ribbon dimensions, installation position and rotation condition all influence the material movement inside the equipment and need to be adjusted according to equipment specifications and operating requirements.
For different materials, the material of the product-contacting parts also needs to be confirmed in advance. Conventional configurations can be used for ordinary industrial powders, while food, chemical and other applications with hygiene or corrosion-resistance requirements require an appropriate material solution. For food and pharmaceutical powder applications, the selection of contact materials and equipment design may also need to consider relevant hygiene and manufacturing requirements, including FDA Current Good Manufacturing Practice (cGMP).
After assembly, the equipment is inspected for ribbon operation, transmission performance and discharge conditions. The Horizontal Ribbon Mixer is delivered for use after confirming that all components operate properly.
