High‐speed ball‐milling: Direct mechanocatalysis is a new catalysis concept using high speed ball milling conditions. The surface of the milling balls is the catalytic active site, hence the recovery of the catalyst is convenient and efficient. Being a solid state technique, solvent related problems are omitted.

Brief introduction. The ball mill is the key equipment for crushing the material after it is crushed. Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and nonferrous metal beneficiation and glass ceramics and other production industries, dry or wet grinding of various ores and other grindable materials.
