Reduce costs and improve the quality of your manufacturing with this technology. Prepare your company for future demands and stay competitive.

    Trajectory mixing

    Trajectory Mixing involves mixing materials through the movement of the container along a 2-dimensional curved path. These movements follow precise patterns known as Lissajous figures. The resulting accelerations generate shear and tensile forces, which efficiently achieve a homogeneous mix. The ability to control the movement parameters allows the mixing quality to be tailored to specific requirements.

    Why trajectory mixing for technical materials?

    Uneven raw material blends lead to quality fluctuations and high scrap rates. With trajectory mixers from hs-tumbler, you achieve precise microstructures, reduce agglomeration, and lower your production costs.

    Benefits at a glance

    • High-precision distribution: Uniform particle dispersion for improved product strength
    • Low agglomeration: Fine dispersion minimizes defects in ceramics and refractory materials
    • Scalable: Linear transfer from lab to industrial scale

    Application examples

    • Ceramics: Optimal microstructure for technical and decorative ceramics
    • Refractory materials: Uniform mixing of oxides for high thermal resistance
    • Minerals: Homogeneous processing of mineral powders for specialized applications

    The manufacturing of technical ceramics requires precise control over the distribution and homogeneity of the raw materials used. These ceramics, often composed of a mixture of oxides, carbides, and other mineral compounds, must have a uniform microstructure to achieve their high mechanical and chemical properties. The success of the manufacturing process depends significantly on the quality of the initial material mixture.

    Advantages of Trajectory Mixing:

    • Uniform Distribution: Ensures a homogeneous mixture of raw materials, leading to a consistent microstructure and improved mechanical properties.
    • Reduced Agglomeration: Minimizes agglomerate formation and achieves fine particle dispersion, reducing defects in the final structure.
    • High Homogeneity: Achieves consistent particle size distribution, reducing variability within the mixture.
    • Gentle Processing: Minimal energy input prevents excessive stress on particles, enhancing the quality of suspensions or powder mixtures.
    Trajectory mixing offers an advanced method for producing refractory materials, representing a valuable innovation in the mixing process. This technique enables precise and uniform distribution of raw materials like aluminum oxide, magnesium oxide, and silicon dioxide. The targeted mixing improves the quality and stability of the final products, which is crucial for thermal and mechanical performance.

    Advantages of trajectory mixing:

    • Homogeneous material distribution: Trajectory mixing ensures uniform distribution of all components during the mixing process. This homogeneity leads to consistent material quality and stable end products, as the even dispersal of raw materials minimizes weak points and quality variations.
    • Gentle material handling: The controlled energy input in trajectory mixing reduces shear forces, which is especially beneficial for sensitive materials. This gentle treatment helps preserve the integrity of raw materials and improves processing quality.
    • Increased efficiency: Targeted mixing enables a significant reduction in the time required for the mixing process. This results in higher productivity and lowers the effort for lengthy mixing procedures, thereby optimizing the entire manufacturing process and making it more cost-effective.

    Quality Assurance and Process Optimization

    Measurement and Optimization of Mixing Quality

    A key aspect in food production is ensuring mixing quality, quantified by analyzing distribution variance.

    • Continuous Monitoring: Allows early detection and correction of deviations, ensuring consistently high product quality.
    • Optimization of Process Parameters: Experimental studies and simulations support determining and adjusting optimal mixing parameters for various applications.

    Process Control and Automation

    The integration of trajectory mixing into automated production processes enables precise control and optimization of mixing operations.

    • Automated Mixing Processes: The ability to tailor movement profiles individually makes trajectory mixing ideal for use in automated production environments.
    • Efficient Resource Utilization: Through automation and precise control of mixing processes, resources can be utilized more efficiently, minimizing waste.

    Advantages of Trajectory Mixing

    • High flexibility: Product-specific trajectory curves that can dynamically adapt to your products’ requirements enable a wide range of applications for diverse materials and mixing needs.
    • Gentle process: The minimized energy input of this method protects raw materials and prevents damage. This is especially important for sensitive feedstocks that would be compromised by conventional agitators.
    • Space savings: The compact design of the trajectory mixer is ideal for production environments with limited floor space.
    • Small-batch processing: Trajectory mixing allows for the handling of very small quantities, which is particularly advantageous in research and development as well as in artisanal applications. The process is linearly scalable from lab scale to full industrial use.
    • Reduced cleaning and setup effort: Eliminating traditional mixing tools like paddles or kneaders significantly lowers contamination risks and reduces cleaning and maintenance time. This leads to lower operating costs and higher availability of the mixing equipment.

    Electrode slurry homogeneous – energy-efficient and tool-free

    Trajectory mixing disperses active material, conductive carbon black and binder through the motion of the sealed vessel – with no agitator in the product.

    • Energy: 60–90 % below conventional mixing, battery slurry up to ~98 % (determined with the PEM chair of RWTH Aachen); developed in the BMFTR project KOOP (Na-ion / hard carbon).
    • Tool-free: no moving source of abrasion in the product; the vessel wall is the single contact surface – material freely selectable, coated if required.
    • Gentle & homogeneous: energy introduced via the path motion instead of a local shearing tool – without local shear peaks.
    • R&D/pilot-ready & throughput: reproducible batches on demand, K1→J4 scalable; swap the vessel instead of cleaning; micro-batch-continuous – throughput instead of vessel size.

    Temperature control without hotspots

    The entire product travels along the temperature-controlled vessel wall on a Lissajous path; the shear keeps the thermal boundary layer thin. Heat transfers quickly and evenly across the jacket surface – homogeneously rather than near-wall, with no dead zones and no hotspots.

    Vacuum & de-gassing

    No agitator reaches into the vessel, so there is no shaft feed-through to vacuum-seal. Vacuum is easy to apply and control – for example to de-gas the slurry before coating.

    A good fit when …

    • electrode slurry / active materials must be dispersed homogeneously
    • thermally and solvent-sensitive formulations need gentle mixing
    • R&D and pilot quantities with frequent material changes occur
    • energy efficiency and throughput matter

    Less in focus when …

    • a single very large volume per mixing run is mandatory (vessel size)
