Cement Manufacturing Process Phase V: Cooling and Final Grinding After passing out from the kiln, clinkers are cooled by mean of forced air. Clinker released the absorb heat and cool down to lower temperature. Released heat by clinker is reused by recirculating it back to the kiln. This too saves energy.

The last stage of making cement is the final grinding process. In the cement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. This powder is the final product, cement.

The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical roller mills (VRM) have a higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement.
