  How Cement Is Made

  The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix ...

  Grinding Process: From Rough to Polished - Transforming Concrete ...

  Understanding Concrete Grinding. Concrete grinding is the process of using abrasive tools to remove the top layers of a concrete surface. This is typically done to eliminate imperfections, level out uneven surfaces, or prepare the concrete for further treatment, such as polishing or coating. 2. The Initial Rough Grind
