I. Technical Positioning

The vertical nano-cellular mill is a new type of continuous nanoscale grinding equipment designed for the materials industry of the future. Specifically developed for applications involving high-solid-content, high-viscosity, ultra-fine nanopowders and slurries, this equipment features a vertically integrated structure. + Specialized energy-transfer disc + Screenless separation + Seal-free fluid discharge structure + No rotating joints—under these conditions, featuring no mechanical seals, no screens, and no rotating joints, we achieve highly efficient, stable, and scalable continuous grinding of particles below 100 nm. Moreover, under the aforementioned operating conditions, we can stably prevent leakage of 0.1 mm grinding-media balls.

Suitable for: Lithium-ion battery cathode and anode materials, cell disruption, ceramic powders, magnetic materials, nano-oxides, functional coatings, and ultrafine pulverization in biomedicine.

II. Core Working Principle

The vertical nano-cell mill employs a multi-stage cell-type energy disc, whose surface can generate shear forces. The synergistic nano-force field—combining collision, cavitation, and vortex self-pressurization—enables the grinding media to follow an approximate “three-dimensional honeycomb-like high-energy trajectory.” Under the action of instantaneous, highly targeted energy, the materials undergo stripping, cleavage, shearing, and pulverization, thereby achieving a breakthrough in particle size down to the nanoscale level.

The separation of materials from grinding media employs a dynamic flow-field separation system, with the core feature being the differentiation based on the density difference between liquid and solid phases. + Annular flow field + superposition of fluid pressure differences to achieve separation, while ensuring no leakage of the medium sphere. ； No screen filtration required—no clogging or wear of screen pores. ； The separation process does not involve direct friction with the grinding media and does not damage the microspheres. ； The entire separation process does not cause blockage, high wear, or leakage risks. ； The final material is discharged directly through a non-contact discharge channel, with no rotating joints, no mechanical seals, and no pressure-friction surfaces throughout the entire process.

Three, Key structural innovation

Structural features: A vertically integrated cylinder with no main shaft running through it; therefore, there’s no issue of reduced strength in a hollow main shaft. It employs fluid dynamics and density differences to automatically separate the medium from the slurry without the use of a screen. The design features a non-mechanical seal—meaning the main shaft does not establish a pressure-sealed interface with the cylinder. 100% maintenance-free; no rotating joints—no need for rotating joints in the discharge process, thus eliminating the risk of wear and leakage. The entire system features self-circulating cleaning, with the medium itself flushing and reshaping the flow field to ensure no accumulation and no blockage. On-line, low-energy power transmission: a specialized energy disk amplifies power down to the level of microscopic particles, maximizing energy efficiency per unit.
