Precision Grinding Sand Mill for MLCCs - High Efficiency from China Suppliers and Factory
Precision Grinding Sand Mill
Professional submicron dispersion solutions for MLCC slurries, electronic ceramics, and functional nano-materials.
High Dispersion Efficiency
Achieves submicron D50 (0.50–0.63 μm) for uniform distribution and optimal electrical performance.
Precise Temperature Control
Active cooling system maintains slurry stability, preventing solvent evaporation and overheating.
Zirconia Ceramic Tank
High-purity zirconia-lined chamber ensures zero metallic contamination for electronic components.
Submicron Particle Dispersion Efficiency
The sand mill achieves high-precision particle size reduction with a rate ≥ 0.1 μm/h. It is specifically designed to refine slurry from D50 = 0.8–1 μm down to 0.50–0.63 μm, ensuring that D90 remains under 1.3 μm. This level of control is critical for LTCC and MLCC processing where uniform dielectric properties are required.
Advanced Thermal & Solvent Management
Equipped with a forced sealing solvent circulation cooling system, the machine maintains strict temperature stability during high-speed milling. This prevents the degradation of heat-sensitive ceramic formulations and stops solvent evaporation, which is essential for maintaining consistent slurry viscosity across 100+ batches.
Precision Speed & Automation
Utilizing a Variable Frequency Drive (VFD), the rotating shaft offers stepless speed control from 0 to 1500 RPM. Integrated pressure sensors in both the feed pump and grinding chamber, combined with real-time feedback, allow for a fully automated and stable milling process without manual intervention.
Superior Slurry Uniformity
Our technology guarantees a tight particle size distribution curve with a uniformity index (D90-D10)/D50 ≤ 1.5. By eliminating minor peaks in the distribution, the system ensures consistent coating quality for multi-layer ceramic stacks and high-frequency electronic substrates.
High-Purity Material Integrity
The grinding tank is constructed from high-purity zirconia ceramic, providing excellent wear resistance and ensuring no impurity is introduced during the milling of sensitive materials like alumina, silicon nitride, or conductive pastes.
Integrated Safety & Closed Circulation
The fully enclosed design features a closed circulation system to minimize dust and environmental impact. Multi-layered safety protections, including liquid level, pressure, and temperature sensing, combined with explosion-proof piping, ensure safe industrial-scale production.
