Question: How Hot Is A Cement Kiln?

Question: How Hot Is A Cement Kiln?

In a typical cement kiln some 200 tonnes per hour of sintering material passes the burner(s). The ashes of the fuel used to heat the kiln drops into the glowing material and reacts with the hot minerals to become an integral part of the endproduct – clinker. This clinker is then ground into cement. What is cement rotary kiln?
