Fine dry grinding with cylpebs of quartz sand in the Şile, district of Istanbul, Turkey

Abstract

Glass and ceramic industries are the main consumption areas of quartz sand, which is a formed as a result of the weathering of igneous metamorphic rocks. In such industries, it is very important to select the correct ball size in order to grind the raw material to the desired particle size in optimum time. In this study, the changes in the specific rate of breakage of the quartz sand sample were investigated by using cylpebs of three different sizes. For this purpose, three different mono-size samples were prepared according to 4√2 series in the range of 0.090-0.053 mm. The quartz sand prepared in these three intervals were ground with 10×10, 20×20 and 30×30 mm cylpebs for different durations. Specific rate of breakage values were obtained from the particle size distributions acquired after various grinding periods. As a result of grinding tests, an increase in rate of breakage is observed due to the increase in cylpebs diameter.
