Highly dispersed CuO/SiO2 catalysts were successfully synthesized by a green process of ball milling (BM) under solventfree and room temperature conditions. The structural evolution of CuO/SiO2 catalysts prepared by BM was elucidated by TGDSC, XRD, FTIR, and XPS characterizations. We found that the copper acetate precursor was dispersed over the layer of copper phyllosilicate which was ...

Lime silica and alumina get recombine. The fused mass turns into a nodular form called clinker. The clinker drops into the rotary cooler, where it is cool under control conditions. The cool clinker is then ground in a ball mill with the addition of 2 to 3% of gypsum. In the ball mill, particles crush to a fine powder and filled into bags.
