Investigation to fine grindability of marble wastes in a stirred mill

In this study, waste marble pieces taken from Marfam Marble?s factory were crushed below 1 mm and then dry grinding properties were investigated in a laboratory scale pin-type vertical stirred mill. Operating parameters such as stirring speed, filling rate and stirring time have a considerable effect on the fineness of the product were investigated. Different grinding experiments were carried out for all operating parameters. Zircon beads with diameters of 3,5-2,00 mm were used as the grinding media. The effect of stirring speed and stirring durations determined by grinding at different five speeds (360, 540, 720, 1080 and 1440 rotation per minute. Under the effect of filling rate of four different filling rates (%60, %80, %100 and %140), experiments were carried out in different times. Size analyzes and chemical properties of micronize milled marble wastes were determined. It was investigated to acceptability of the marble wastes area of usage in order to regain the marble wastes to industry.
