  • Cement kiln Wikipedia

    Higher SO 2 emissions by rotary kiln systems in the cement industry are often attributable to the sulfides contained in the raw material, which become oxidised to form SO 2 at the temperatures between 370 C and 420 C prevailing in the kiln preheater.

  • China Vertical Preheater for Cement Plant Rotary Kiln

    It is based on the position of preheater in rotary kiln system and negative pressure. Heat emission is heat convective, the material and air is convection movement. When raw materials are fed into the preheater, under the negative pressure condition, to prevent cold air into the preheater, the inlet of raw materials must be effectively sealed.
