Laboratory Horizontal Pin Nano Sand Mill

Product Overview

This laboratory horizontal pin nano sand mill is a high-energy wet grinding system specifically engineered for nanoparticle production and ultra-fine dispersion in research and development settings. It employs a pin-type rotor within a sealed grinding chamber filled with micro-sized grinding beads. As the rotor spins at high speed, the pins accelerate the beads, creating intense zones of impact, shear, and friction. This multi-directional energy transfer rapidly reduces particle sizes down to the nanometer scale, achieving uniform dispersions essential for advanced material formulations.

The equipment serves as an indispensable tool across a wide spectrum of cutting-edge industries, including new energy (lithium battery electrode materials, graphene and CNT conductive pastes), advanced ceramics (ceramic inks, MLCC dielectrics), pharmaceuticals (nano-drug delivery systems), and specialty coatings (stealth materials, wear-resistant composites). Its ability to process both water-based and solvent-based slurries, coupled with precise process control, makes it ideal for developing scalable nano-material processes.

Designed with modularity and durability at its core, this mill features a jacketed grinding chamber and material tank for effective cooling, preserving heat-sensitive materials and maintaining process stability over long milling cycles. The availability of interchangeable chamber components in high-purity ceramics and polymers ensures minimal contamination and exceptional wear resistance, meeting the rigorous demands of academic and industrial research labs where reproducibility and long-term reliability are paramount.

Key Features

• Advanced Pin Nano-Grinding Mechanism: The uniquely designed pin rotor generates high tip speeds and turbulent bead motion, maximizing collision frequency and energy transfer for rapid particle size reduction. This mechanism achieves median particle sizes below 100 nm, far surpassing traditional disc mills in efficiency for nano-dispersions.
• Seamless Scalability from Lab to Production: Process parameters such as rotor speed, media size, and residence time can be directly correlated with larger production-scale mills. This ensures that formulations developed in the lab can be reliably scaled up to pilot and full manufacturing without extensive re-optimization, saving time and resources.
• Comprehensive Material Compatibility: The grinding chamber and rotor are available in multiple wear-resistant materials including high-purity zirconia, silicon carbide, silicon nitride, and polyurethane. This flexibility allows users to select the optimal material combination for their specific slurry chemistry, virtually eliminating metallic contamination and ensuring product purity.
• Integrated Temperature Management: Both the grinding chamber and the 1-liter material tank feature jacketed cooling circuits that efficiently dissipate frictional heat. This prevents thermal degradation of temperature-sensitive additives and maintains stable viscosity, crucial for achieving consistent particle size distributions and dispersion quality.
• Precision Process Control: A Siemens 7-inch touchscreen paired with a PLC controller offers intuitive, recipe-based operation. Users can set and monitor key parameters such as grinding time, rotor speed, and pump flow, enabling accurate replication of experiments and easy data logging for quality assurance.
• Self-Priming Conveyance System: The mill utilizes a self-priming design that eliminates the need for an external feed pump, simplifying the setup and reducing maintenance. The integrated system reliably draws slurry from the material tank, ensuring consistent and pulsation-free flow into the grinding chamber.
• Vibration-Minimized Stability: Rugged construction and optimized rotor balancing drastically reduce vibration during operation, extending component life and ensuring quiet, stable running. This precision engineering allows the unit to operate on standard lab benches without special mounting.
• Versatile Media Selection: The mill supports a wide range of grinding media types and sizes (0.3–1.4 mm), including yttria-stabilized zirconia, alumina, silicon nitride, and stainless steel. This versatility enables the ideal media choice for different materials, optimizing grinding efficiency and minimizing media wear.
• Low-Contamination Design: All product-contact surfaces can be specified in non-metallic, high-purity ceramics to meet the strictest contamination-free requirements. This design is particularly critical for advanced ceramics and electronic materials where even trace metal impurities can compromise performance.
