Innovations in dry kiln designs for higher efficiency - Decarbonizing cement industry Innovation Insights - CLIMAX
There are two main types of cement kilns used for the production of clinker: vertical shaft kilns and rotary kilns. A rotary kiln consists of a longer and wider drum oriented horizontally and at a slight incline on bearings, with raw material entering at the higher end and traveling as the kiln rotates towards the lower end, where fuel is blown into the kiln
Rotary kilns are either wet or dry process kilns. Wet process rotary kilns are more energy-intensive. Dry process rotary kilns are more energy efficient, and these can be equipped with grate or suspension preheaters to heat the raw materials using kiln exhaust gases prior to their entry into the kiln.
