What is a Grinding Aid? (with picture) wisegeek

Jun 19, 2019· Grinding aid is a chemical agent used to make it easier to grind and mix cement. Mills save money and power when using these aids because the aids transform the cement-making process into an endergonic process, consuming energy from the surrounding environment. Because cement aids allow the cement mixture to absorb energy,

Corn Milling Process | North American Millers' Association
