Ragland, AL 35131
National Cement Company (NCC) established a cement processing plant in
A program of modernization and expansion was immediately implemented by the company to triple the cement plant’s production capacity while greatly reducing its level of emissions and energy consumption.
In 1976, the long dry kiln was retrofitted, and a preheater/precalciner system was installed, making it the first kiln in the world to be fueled by burning 100% coal. Two years later, a vertical raw mill was installed to recycle exhaust gases from the pyro‑processing line, which further reduced the overall energy consumption of the plant.
In keeping with NCC’s commitment to continuous improvement of its energy efficiency at the Ragland plant, a fully-automated packing plant was installed in 1994. In 2006, a state of the art vertical cement mill was installed, which reduces the power used to grind cement by 50 percent. These additions also allow the plant to operate off the peak power consumption hours.
Additionally, during the past 5 years, the plant has focused on reducing its carbon footprint by recycling by-products and raw materials and using alternative materials to replace fossil fuels to fire the kiln.
Based on these conservation efforts, the Ragland Plant was awarded the 2010 ENERGY STAR certification for the first time.
