Abstract
The grinding efficiencies of silica powder in a small scale stirred ball mill were investigated by energy consumption estimate. Comparing with a non-treated silica powder and a heating treated silica powder, it was found that a silica powder cooled in room temperature after heating treatment at 600∼900$^{\circ}C$ consumed lower grinding energy than non-treated silica powder, and a silica powder quenched after heating treatment consumed lower grinding energies about 52∼62%, in case of dry grinding. Additionally, if heating treated silica powder grind in wet method, energy consumption will be decreased about 40% than in dry grinding, and the dependency of the particle size to the grinding efficiency, quenching significantly improved it.
