  • What is a Grinding Aid? (with picture) wiseGEEK

    · Mills save money and power when using these aids because the aids transform the cementmaking process into an endergonic process, consuming energy from the surrounding environment. Because cement aids allow the cement mixture to absorb energy, less external energy is needed for the reactions to take place. In this way, industrial mills save a tremendous amount of money by employing cement .
