Effect of fineness of wear particles from steel balls on the rate of hydrogen generation during wet grinding of hard materials in water

Alumina and silicon carbide powders were ground in water, butanol, benzene and hexane using planetary ball mill, and the gas phase inside the mill pot was analyzed by a gas chromatograph. The effect of liquid media on the grindability varied with the kind of feed powders, and the main product in the gas phase was hydrogen. The amount of it was in the order of benzene ≤ butanol < hexane for alumina and no gas product was detected for water. However, that for silicon carbide was considerable in water and in butanol, and was very small in benzene and in hexane. The mechanism of these mechanochemical reactions was discussed.
