  • Raw Mill In Cement Plant Cement Making Plant

    A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It s mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part discharging part rotating part transmission part (reducer samll transmission gear motor electric control) etc. Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
