### 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.

### Portland cement - Wikipedia

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the ...
