Cement mill - Wikipedia

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.

SINTEF Building and Infrastructure Christian J. Engelsen

Grinding aids are mostly organic compounds that are added to the clinker in the cement mill. Their main purposes are to reduce the energy required to grind the clinker into a given fineness and therefore increase the efficiency of the cement mill. Grinding aids have been used for more

What is a Grinding Aid? (with picture) - wisegeek.com

Jul 28, 2019· 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 re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.

Cement Clinker Grinding Aids - Mineral Processing & Metallurgy

The use of a good Cement clinker grinding aid can be vital in today's increasing material demands.
