Technical Analysis and Application Panorama of N Series Circulating Bead Mill
The N series circulating bead mill has set an industry benchmark in the field of nanoscale grinding with its innovative design and precise craftsmanship. Its core advantages are reflected in the following aspects:
1.**High-efficiency separation system**
The newly designed centrifugal separation device adopts dynamic gap control technology, achieving a 30% increase in flow rate while ensuring smooth discharge and avoiding medium blockage issues. It is particularly suitable for high-viscosity materials (such as ceramic slurry and lithium battery cathode materials).
2. ** Golden Section Structure Optimization **
The layout of the rotor and the cylinder strictly follows the golden ratio. Through fluid mechanics simulation verification, the grinding energy utilization rate has been increased to 92%, the wear rate has been reduced by 40% compared with traditional models, and the service life of key components has been prolonged.
3. Dual Cooling technology
The internal and external circulation cooling system can precisely control the temperature within ±2℃ range. Combined with a large flow of cooling water (up to 8000L/h), it effectively solves the heat-sensitive problems in the grinding of nanomaterials, such as the thermal stability control of inkjet dyes.
4. ** All imported core components **
The equipment is equipped with German mechanical seals, Swedish SKF bearings, Italian corrosion-resistant transfer pumps and other configurations, ensuring its reliability under 24-hour continuous working conditions, with the MTBF (Mean Time Between Failures) exceeding 10,000 hours.
5. ** Broad medium adaptability **
It supports various grinding media such as zirconia and glass beads with a diameter of 0.1mm or more. The linear speed can be infinitely adjusted through variable frequency speed regulation (3-20m/s), meeting the full-process requirements from coarse grinding to ultrafine nanometization.

II. Application Fields
The N series, with its environmentally friendly, energy-saving and stable characteristics, has permeated into the following high value-added industries:
- ** New energy field **
The nanoscale dispersion of lithium battery materials (lithium iron phosphate, ternary precursors) can control the particle size D50 within 200nm, and the solid content of the slurry can be increased to over 75%.
- "Electronic Chemicals
The ultrafine grinding of nano-color pastes for TFT/LCD filters and OLED packaging materials, with a particle size distribution CV value of less than 5%, significantly improves the color gamut uniformity of display panels.
"Advanced Ceramics
Sub-micron preparation of functional ceramics (MLCC medium, alumina substrate), with a specific surface area of 15m²/g and a 20% increase in sintering activity.
- Food and Medicine
The production of additives such as nano calcium and vitamin E in compliance with FDA standards avoids the risk of metal contamination, and the total number of colonies is controlled to be less than 100CFU/g.
- "Environmentally friendly materials
The dispersion of silica sol in CMP polishing slurry to achieve a surface roughness Ra < 0.5nm is applied in the manufacturing of semiconductor wafers.
