Working Principle:
| NORVA High-Efficiency Nano Bead Mill adopts a pin-type structure design. The material enters the grinding chamber from the top via the feed pump, is evenly distributed as the rotor rotates, and undergoes thorough pre-dispersion treatment under the action of eddy current centrifugal force within the gaps between the rotor and stator. During the subsequent intense grinding process, the rotor pins and stator continuously generate剧烈的撞击 changes on the grinding media, which in turn act on the material, achieving grinding. The ground material has an extremely short residence time in the grinding chamber, resulting in a very narrow particle size distribution. Under the pressure of the feed pump and centrifugal force, due to differences in density, the grinding media return to the grinding chamber, while the material moves in the opposite direction of centrifugal force, passing through a gap-type separator for filtration and separation, in a continuous循环往复 process. |
Structural Design
The core design rotor is equipped with imported wear-resistant steel rod pins, whose quantity, volume, and installation positions are designed based on vortex fluid mechanics to achieve an optimized grinding energy ratio, improve material grinding efficiency, and enable the material grinding fineness to reach the nanometer level. As measured by a third-party Malvern laser particle size analyzer, the minimum fineness can reach ≤60nm.
Main Features:
* High energy density (1.5-2.3 kW/dm³) pin-type bead mill
* Has a smaller length/diameter ratio;
* Designed for high-volume production (continuous or cyclic);
* The product has a narrow particle size distribution;
* The separation system of the sand mill is highly efficient, achieving a separation efficiency 200-300 times that of traditional sand mills.
* Usable grinding beads * Minimum particle size: 0.1mm;
* The material of the grinding cylinder can be replaced according to the requirements for wear resistance and corrosion resistance.
* The viscosity range of the slurry used is broad, from 10 mPas to 8000 mPas.
* Due to the use of a dual forced cooling system in the grinding cylinder and separation system, the temperature of the discharged product is low (generally ≤35°C).
* Easy to operate and process control;
