Applications Where Trajectory Mixing Excels
Trajectory Mixing addresses the fundamental quality challenges in specialty formulation production. The technology is ideally suited for manufacturers where batch quality, contamination-free processing, and flexible small series production are paramount. The modular architecture enables scaling from laboratory quantities to industrial volumes.
High-Performance Castables
Scientific research demonstrates that cold modulus of rupture reaches its maximum at 90 seconds mixing time. Homogeneous distribution with coefficient of variation below five percent leads to more uniform mechanical properties and measurably extended service life. Particularly valuable for critical applications with stringent quality requirements in the steel industry. Zero percent metal abrasion contamination guarantees chemical purity without compromise.
Temperature-Sensitive Formulations
Ideal solution for modern PCE-based castables. Research results with silicon carbide and polycarboxylate ether demonstrate that temperature increase remains minimal while fluidity is optimally preserved. Controlled temperatures between 18 and 25 degrees Celsius prevent thermal desorption of dispersing agents and completely eliminate flash-setting risks. Gentle mixing preserves the full effectiveness of temperature-sensitive additives.
Research and Development
Excellent for systematic formulation development and materials research. Reproducible results through mathematically defined Lissajous trajectories enable precise experimental series. Rapid product changeover with 70-second container exchange time maximizes efficiency in new formulation optimization. Small batch sizes starting at 15 kilograms reduce material consumption during development phases. Scientific validation at Koblenz University of Applied Sciences confirms the technology's precision.
Pharmaceutical and Food-Grade Production
International FoodTec Award Gold 2024 confirms suitability for highest purity requirements. Zero percent metal abrasion contamination meets GMP standards without compromise and eliminates the risk of costly product recalls due to foreign particles. Documentable purity and reproducibility meet the strictest requirements of regulated industries. Validatable processes for pharmaceutical environments guarantee batch-to-batch consistency.
Specialty Production with Frequent Changeovers
Perfect solution for manufacturers with diversified product portfolios. The four-container system enables 90 batches per hour at a throughput of 2.2 tons. Exchange of all four containers occurs in only 70 seconds, supporting flexible production changeovers without significant time loss. Minimal cross-contamination through simple container cleaning outside the machine. Ideal for custom formulations and small lot sizes with highest quality requirements.
Battery Electrodes and Technical Ceramics
Gentle mixing without particle damage preserves the integrity of active materials. Homogeneous electrode mass slurries measurably improve cycle stability and electrochemical properties. For technical ceramics, precise binder distribution enables uniform densification and superior sintering results. Contamination-free processing is critical for high-tech ceramics in electronics and medical technology.
Scientifically Validated Through Research at Koblenz University of Applied Sciences
The superiority of Trajectory Mixing for refractory castables has been scientifically demonstrated through systematic research at Koblenz University of Applied Sciences. The results clearly show that conventional mixing techniques represent the critical first phase in castable production, directly influencing material properties.
Validated Research Results for Silicon Carbide with Polycarboxylate Ether
Test series with highly abrasive silicon carbide formulations and modern PCE dispersing agents document the technology's performance under realistic production conditions. Cold modulus of rupture reaches its maximum precisely at 90 seconds mixing time, defining the optimal balance between homogeneity and processing time. Fluidity remains stable throughout the entire mixing process, without the degradation typical of conventional high-shear mixers. Particularly noteworthy is the minimal temperature increase, which prevents thermal desorption of temperature-sensitive PCE molecules and preserves full dispersing effectiveness. Mechanical strength significantly exceeds conventionally mixed comparison samples, confirming the superior homogeneity of Lissajous-based mixing.
Measurable Quality Advantages
Research data demonstrates quantifiable improvements over conventional methods. The coefficient of variation consistently remains below five percent, while traditional paddle mixers typically achieve values between eight and twelve percent. This superior homogeneity manifests as more uniform distribution of aggregates and additives, minimizing local weak points and measurably extending service life. Reproducible mixing conditions through mathematically defined trajectories guarantee batch-to-batch consistency unattainable with manually controlled systems.
Temperature Control as Quality Factor
Research results demonstrate the direct relationship between temperature control and product quality. While conventional high-shear mixers generate temperatures above 32 degrees Celsius through intensive mechanical processing, Trajectory Mixing remains in the optimal range between 18 and 25 degrees Celsius. This is particularly critical for modern PCE-based formulations, where thermal desorption drastically reduces dispersing effectiveness and can lead to premature setting. Controlled temperature extends processing time and improves fluidity during casting.
Technical Specifications and Production Throughputs
HS-Tumbler Trajectory Mixing systems cover a broad spectrum from laboratory applications to industrial specialty production. External container handling enables parallel filling and emptying during the mixing process, maximizing productivity. Larger container variants in development continuously expand the application spectrum.
K1 Laboratory and Development System
Excellent for formulation development, materials research, and small production batches. With a volume of 0.75 to 4.5 liters and a processing capacity of up to 10 kilograms of process material, the K1 enables precise trials with industrially relevant quantities in a compact form. This high capacity is particularly valuable for specialty ceramics manufacturers processing high-density powder mixtures. The compact design fits any laboratory, while Trajectory technology guarantees the same mixing quality as industrial systems. Scientific validation at Koblenz University of Applied Sciences was conducted with this system, demonstrating precision and reproducibility even with smallest batches. The ability to process significant material quantities despite small volume significantly reduces the number of required batches during development phases and accelerates product development. Optional thermal extension for temperature control up to 150 degrees Celsius and vacuum generator further expand application possibilities.

Process containers are filled and emptied externally while undergoing the 90-second mixing process in the machine. After 90 seconds, all four containers are exchanged together in only 70 seconds. This intelligent logistics enables 22.5 cycles per hour, which with four containers equals 90 batches per hour. With 14.5 liters useful volume per container and typical ceramic density of 1.7 kilograms per liter, the system achieves a throughput of 2.2 tons per hour. The automated design reduces operator errors and guarantees reproducible quality across all batches.

- Annual production: approximately 4,400 tons (8 hours daily, 250 days)
- Advantage: External filling and emptying parallel to mixing process
- Application range: Quality-oriented specialty production with industrial volumes
Intelligent Four-Container Logistics Maximizes Productivity
The J4 system utilizes a sophisticated four-container concept combining highest quality with industrial productivity. All four containers mix simultaneously during the scientifically optimized 90 seconds. After completion of the mixing process, all four containers are exchanged together in only 70 seconds. This results in a total cycle of 160 seconds, enabling 22.5 cycles per hour. Since each cycle completes four containers, the system achieves 90 batches per hour. External filling and emptying occurs completely parallel to the mixing process, eliminating wait times. With 14.5 liters useful volume per container and typical material density of 1.7 kilograms per liter, batch size is 24.65 kilograms, resulting in a throughput of 2.2 tons at 90 batches per hour. This logistics makes the system particularly efficient for applications requiring highest quality standards with industrial production volumes.
Scaling for Growing Requirements: Larger Containers in Development
The modular system concept enables continuous scaling for growing production volumes. We are currently developing larger container variants guaranteeing the same quality level at higher throughputs. The next planned size is containers with 70 liters useful volume, which at the same cycle time of 160 seconds and four containers would enable an estimated throughput of approximately 8.5 tons per hour. This is followed by containers with 250 liters useful volume, potentially achieving an estimated throughput of approximately 30 tons per hour. These developments demonstrate the technology's scalability for growing production requirements. The same scientifically validated mixing principles guarantee superior quality and reproducibility even at larger volumes. Contact us directly for current information on development status.
Quality Challenges in Refractory Production
Mixing is the critical first step in castable production. The quality of this phase directly influences refractory material quality and mechanical properties. Studies show that 20 to 30 percent of all premature failures are attributable to insufficient mixing quality. Conventional methods struggle with systematic challenges affecting consistency and economic efficiency.
Extreme Tool Wear
Highly abrasive components such as aluminum oxide and silicon carbide cause extreme wear on mixing tools, paddles, and seals. Hard particles attack all mechanical components in contact with the material. Mixing blades typically require replacement every six to twelve months, causing not only material costs but also significant downtime. For specialty formulations with particularly hard aggregates, this cycle shortens further. Unplanned failures due to wear damage impair production planning and significantly increase operating costs.
Contamination Through Metal Abrasion
Mixing blade wear inevitably leads to metal abrasion in the product. For high-performance castables and regulated applications, this is critical. Metal particles can create local weak points and compromise chemical purity, particularly problematic in critical steel industry applications. In pharmaceutical and food-grade applications, metal abrasion is unacceptable and can lead to costly product recalls. Contamination is unavoidable in conventional systems with mechanical mixing tools and worsens with increasing tool wear.
Uncontrolled Frictional Heat
Research results demonstrate that temperatures above 32 degrees Celsius risk premature setting. Modern PCE dispersing agents lose effectiveness through thermal desorption, potentially leading to flash setting. High-shear mixers generate significant temperature increases during mixing through intensive mechanical processing. Controlling this heat development is critical for processing time and final product quality. For temperature-sensitive specialty formulations with PCE-based systems, this is particularly problematic, leading to reduced fluidity and shortened processing times.
The Measurable Costs of Inferior Quality
Insufficient mixing quality manifests as uneven distribution of aggregates and additives, leading to local weak points and microcracks. The result is performance loss up to 25 percent and significantly shortened service life. The coefficient of variation should be below five percent for optimal results, yet many conventional systems achieve only values between eight and twelve percent. This inhomogeneity later manifests as uneven wear patterns in linings and leads to unplanned shutdowns, whose costs often exceed material costs many times over. Scientific research at Koblenz University of Applied Sciences quantitatively documents these relationships and demonstrates direct effects on mechanical strength.
The Solution: HS-Tumbler Trajectory Mixing
The Fundamental Principle
Conventional mixers with mixing tools reach only a small portion of the process mass per revolution. Even powerful systems with multiple mixing tools manipulate only a fraction of the material at any moment. The Trajectory Mixer, in contrast, always manipulates 100 percent of the material simultaneously. The entire mixing container follows complex three-dimensional movement patterns without requiring mechanical mixing tools working in the material. This fundamental principle completely eliminates wear, contamination, and uncontrolled frictional heat.
Comparison: Conventional mixing technology vs. Trajectory Mixing
Lissajous Trajectories for Reproducible Quality
Two independent motion axes generate high-frequency, precise patterns for simultaneous mixing of the entire batch. These Lissajous trajectories are mathematically defined curves resulting from the superposition of two sinusoidal oscillations. The result is uniform, reproducible mixing without dead zones. Each particle traverses a defined path during the 90-second mixing cycle, guaranteeing optimal homogeneity. The broad range of possible trajectories enables adaptation to different materials and viscosities without requiring mechanical system modifications.
Transparency on Wear Behavior
The cylindrical process container experiences wear on the inner wall through material contact. This is physically unavoidable when abrasive materials are moved. The decisive difference lies in maintenance intensity and predictability. The container can be manufactured from wear-resistant material or coated and typically lasts several years without replacement. While mixing tools must be replaced every six to twelve months and their failure causes unplanned downtime, maintenance for the Trajectory Mixer is limited to scheduled inspections. Maintenance costs thereby reduce by approximately 60 to 80 percent, while production planning improves significantly through avoidance of unplanned failures.
