  • Shaft Kiln, Vertical Shaft Kiln, Vertical Kiln Cement

    Shaft kiln, also known as vertical kiln, vertical shaft kiln, is a vertical and fixed clinker firing equipment. The raw meal ball with coal is fed into cement kiln from the kiln crown, and raw meal ball moves from top to bottom, air move from bottom to top. In fact, the physical and chemical changes of shaft kiln are similar to that of cement rotary kiln.

  • Shaft Kiln Vertical Shaft Kiln Vertical Kiln AGICO

    Shaft kiln, also called vertical shaft kiln or vertical kiln, is a kind of vertical set stationary cement kiln, usually applied in the cement production line, lime production line, etc. As one of the main cement equipment, it plays the same role as a cement rotary kiln for cement clinker manufacturing, also composed of preheating zone, calcining

  • Kiln In Cement Plant Cement Rotary Kiln & Vertical Shaft

    Vertical shaft kiln is a kind of vertical cement kiln, the kiln body is upright on the ground and can not rotate. Materials in the kiln move from top to bottom, and the combustion-supporting air flows from bottom to top. The heat carried by the high-temperature materials will preheat the combustion-supporting air, which reduces the heat loss.
