A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from reagglomeration, or readhering, during and after the grinding process. Grinding aids make it possible to streamline the cementmaking process by increasing process efficiency and material fluidity.Get Price
A cement mill or finish mill in North American usage is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. 2 Materials ground. 3 Temperature control.
