What is a nano mill

Pigment ultra-fineness generally uses the ultra-fine grinding method (also called the ultra-fine grinding method). This method mainly uses ultra-fine grinding and shearing of organic pigment particles to homogenize the distribution of pigment particles. In order for organic pigments to have good stability in water, three conditions must be met: Wetting, stabilization and solid-liquid separation.
The ultra-fine grinding of pigments must select appropriate dispersion medium and separation equipment. The ultra-fine grinding method is simple and feasible, as long as there are conventional grinding and dispersing equipment, such as nano-mills.

Nano mills are made of zirconia or silicon carbide and are completely isolated from the metal. In this way, the smooth operation of the material can be ensured. It is commonly used in carbon nanotubes, inkjets, cosmetics, biologics, etc.

Material nanometerization can effectively increase the contact area between the active material and the electrolyte by increasing the surface area of the material, so the transport rate of lithium ions between the positive and negative electrodes can be effectively enhanced, and the electrochemical performance of the electrode material can be enhanced. Therefore, the strict control of the sanding process is crucial in the synthesis and preparation of materials.

The main motor drives the dispersing shaft to move at high speed through the V-belt, and the dispersing disc on the dispersing shaft drives the grinding medium to move to generate friction and shear force to grind and disperse the materials. The equipment adopts mechanical seal to make it fully airtight, thus eliminating the loss of solvent volatilization in production and reducing environmental pollution. On the other hand, since the air is prevented from entering the working cylinder, the dry solidification skin that may be formed during the production process of the material is avoided.
