Manufacturing Process – Continental Cement

The preheater tower supports a series of vertical cyclone chambers through which the raw meal passes on its way to the kiln. To save energy, modern cement plants preheat the meal before it enters the kiln. Rising more than 350 feet, hot exit gases from the kiln and clinker cooler combined with fuels such as ground coal, petcoke, natural gas ...

Life Cycle Assessment of the Cement Industry in ZimbabweThe cement kiln dust produced is harmful to humans and causes respiratory problems and diseases. Dust from the coal mill and the raw meal silos are equally liable. The cement kiln dust is also harmful to plants. Once it settles on the leaves, it deprives them of photosynthesis.
