The wet ball-milling preparation of metal matrix micro-nanometer powder using nanosuspension as the precursor can well solve the agglomeration of nanoscale component, but the micro-nanometer powder prepared by the method can hardly meet the requirement of powder feeding in laser cladding process and its composite effect is still not desirable enough.

A wet mixing process is proposed for filled rubber composites with a high silica loading to overcome the drawbacks of high energy consumption and workplace contamination of the conventional dry mixing process. Ball milling was adopted for preparing the silica dispersion because it has a simple structure, is easy to operate, and is a low-cost process that can be easily scaled up for industrial

2.1. Optimization of Silica Dispersion Preparation. Silica powder can be generally ground in a dry or wet ball milling process. However, dry ball milling gives larger silica aggregates because of the interactions between silica particles by H-bonding of silanol groups. In wet ball milling, silica is dispersed in water during the grinding. This
