Shaft kiln is a thermal equipment for continuous calcination of clinker with upper feeding and lower discharging.It is composed of kiln body, feeding and discharging device and ventilation equipment, etc. It is widely used for calcination of various refractory materials and lime.The advantages of MECRU shaft kiln are less capital construction investment, less occupation area, high maturity efficiency, low fuel consumption and easy automation.
Upper feeding lower discharging continuous calcining clinker. Working according to counter current heat transfer principle.The materials in the kiln move from top to bottom, and the flue gas passes through the whole tower from bottom to top. Materials are preheated, calcined and cooled in the kiln.
