Nano Grinding and Dispersion Introduction

Nano grinding involves the gradual reduction of primary particle size from micrometers and sub-micrometers to nanometer levels through the application of shear force and impact force by grinding media.

Nano dispersion, on the other hand, utilizes shear force, impact force, along with suitable solvents and dispersants to uniformly disperse highly aggregated nano powders to nanometer levels.

Why Choose Wet Grinding and Dispersion Equipment?A: Currently available dry grinding machines are limited in their design, with a final particle size reduction only achievable to a few micrometers. Moreover, dry grinding processes introduce a significant amount of material into the grinding chamber, leading to temperature increases that are difficult to control. Additionally, issues related to workplace safety, such as dust explosions, may arise when dry powders are reduced to fine sizes.

In general, if you aim to obtain sub-micrometer or nanometer-level powders, wet grinding is necessary. Wet grinding involves mixing the grinding powder with an appropriate solvent to form a grinding slurry. Through shear force and impact force applied by grinding media, the powder gradually undergoes nanoscale reduction. Wet grinding is not only highly efficient but also yields sub-micrometer and nanometer-level slurries and powders.

Why Choose Yttria-Stabilized Zirconia Beads?A: There is a wide variety of grinding media available, but yttria-stabilized zirconia offers characteristics such as high hardness, high density, and exceptional surface stability, making it the ideal choice for nano powder grinding and dispersion equipment. It ensures that the grinding samples remain uncontaminated during the grinding process.

How to Separate Grinding Samples from Grinding Media?Batch Process:When using yttria-stabilized zirconia beads as grinding media, their higher density compared to typical grinding samples allows for easy separation after grinding. Simple filtration equipment can be employed to separate the grinding samples from the grinding media.

Continuous Process:Various methods, such as gap separation or centrifugal separation, can be employed to separate the grinding media from the grinding samples.
