Fiber Powder Ribbon Mixer is a horizontal ribbon-type blending machine designed specifically for fiber powders such as glass fiber, carbon fiber, and cellulose fiber. It uses a low-shear folding-and-tumbling motion to achieve mixing uniformity CV ≤ 5% while maintaining fiber length retention ≥ 95%. It is designed to solve common fiber powder problems including agglomeration, tangling, and fiber breakage. The machine supports non-standard customization for capacity, material characteristics, and production conditions. Contact parts and frame can be 304/316L stainless steel or carbon steel. It can also be integrated with feeding, packaging, and conveyor lines for continuous automated production.
The Fiber Powder Ribbon Mixer combines mixing efficiency, mixing quality, and practicality. Firstly, it employs a unique ribbon structure design, resulting in a gentle, non-shearing mixing process that maximizes fiber length and integrity, preventing fiber breakage and clumping. The mixing uniformity far surpasses ordinary mixing equipment, with no layering, dead zones, or residue.The ribbon agitator operates at low shear rates, typically below 50 RPM for fiber applications. Unlike paddle or plough mixers that rely on high-speed impact, the forward and reverse spiral ribbons create a folding-and-tumbling motion that preserves fiber integrity. This design achieves CV ≤ 5% and avoids layering, dead zones, and residue. Secondly, the equipment operates stably with lower energy consumption and moderate stirring force, suitable for viscous, lightweight, and fluffy fiber powders. It supports full-process non-standard customization, adapting to special working conditions and material requirements. With various additional functions to enhance automation, it improves production efficiency, ensures product quality stability, and reduces material loss and labor costs.
The Fiber Powder Ribbon Mixer has a compact and rational overall structure. Its core consists of a mixing cylinder, a double-layer ribbon mixing assembly, a drive motor, a reducer, a discharge device, and a frame. The structural design is tailored to the flow characteristics of fiber powder. The mixing cylinder is primarily a U-shaped horizontal structure with a smooth, burr-free inner wall, reducing fiber residue. The stirring ribbon employs a forward and reverse spiral design, with calculated pitch and gap to fit snugly against the inner wall of the cylinder, ensuring all-around material agitation.For fiber applications, ribbon clearance is typically 3–8 mm depending on fiber type and length. Glass fiber often uses 5–8 mm, carbon fiber 3–5 mm, and cellulose fiber 8–12 mm. Actual clearance should be confirmed with material testing. The drive assembly features a high-quality motor and reducer, providing stable power output and adjustable speed. The overall structure is robust and durable, easy to disassemble and assemble, facilitating daily cleaning, maintenance, and ribbon replacement.
The Fiber Powder Ribbon Mixer achieves three-dimensional mixing of materials through the directional rotation of the ribbon. After startup, the motor drives the reducer to rotate the ribbon spindle at a uniform speed. The inner and outer ribbons create opposing pushing forces. The outer ribbon pushes the fiber powder from the periphery of the cylinder wall along the axis towards the center, while the inner ribbon transports the central material to both ends of the cylinder. Simultaneously, the circumferential agitation creates a complex motion of convection circulation and shear diffusion within the cylinder. The material comes into contact with the surrounding material during this circulation, completing batch mixing in a short time.

Our factory produces two types of Fiber Powder Ribbon Mixers: horizontal and vertical. Customers can choose the type that best suits their production needs and application scenarios, ensuring adaptability to fiber powder mixing in various situations.
Horizontal Fiber Powder Ribbon Mixer: This machine features a legless design, with the entire body directly fixed to the ground or a supporting platform via a base. The horizontal layout of the cylinder results in a low center of gravity, extremely high operational stability, a long mixing stroke, and higher mixing uniformity. It is suitable for large-scale, continuous industrial production, especially for mixing long fibers and high-bulk powders.For long glass fiber or high-bulk powders, horizontal models are usually recommended to reduce fiber breakage.
Vertical Fiber Powder Ribbon Mixer: Equipped with dedicated support legs, the cylinder has a vertical layout, supporting the main unit and leaving space for discharge below. It has a small overall footprint, making it suitable for small workshops with limited space, small-batch, multi-batch production scenarios, or laboratory research and development, and pilot-scale testing. It offers fast discharge speed and thorough discharge, facilitating manual loading or docking with small feeding machines. The roller design allows for easy movement in different production environments.
The Fiber Powder Ribbon Mixer covers multiple production fields involving fiber powder mixing. In the chemical industry, it can be used to mix glass fiber, carbon fiber, and cellulose fiber powders with resin powders, fillers, and additives to produce composite materials, friction materials, and sealing materials. In the building materials industry, it is suitable for blending fiber powders with cement, sand, and additives in thermal insulation mortars, putty powders, and self-leveling materials to improve the toughness of building materials. In the pharmaceutical industry, it is suitable for low-damage mixing of pharmaceutical fiber excipients and active pharmaceutical ingredient powders to meet the cleanliness requirements of pharmaceutical production. In addition, it can also be used in industries such as feed and rubber and plastic modification for mixing various plant fiber, chemical fiber, and mineral fiber powders.For example, in one friction material application, a 2,000 L horizontal model mixed glass fiber and resin powder with CV ≤ 5% in 10 minutes.
The Fiber Powder Ribbon Mixer can comprehensively optimize the user experience for the special process requirements of fiber powder mixing. It can be flexibly configured as needed to further broaden the applicable scenarios, improve production efficiency and mixing quality, and adapt to various customized production conditions.
