Step 2: clinker sintering. Clinker sintering is a crucial link in clinker calcination, which mainly occurs in the cement kiln. Inside the kiln, raw meals are heated by rising temperature and generate a series of physical and chemical reactions. When the temperature reaches its peak, the clinker will be produced by rapid cooling.

The efficiency of fine grinding in the second compartment is largely controlled by the size of grinding balls. Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range ...

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.
