• Cement Milling

    This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris 2CaSO 4.H 2 O.

  • Kiln Feeding Cement Plant Optimization

    As the chemistry of this dust is normally different from kiln feed composition, therefore kiln feed must be adjusted/biased to yield the desired clinker composition. Major portion of this dust is taken to raw mill and coal mill with hot gases and a part of it is directly precipitated in bag filter or electrostatic precipitator before flue gases

    A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m
