The kiln is the heart of a cement plant and where most of the final chemical reactions take place stay competitive by investing in our topquality rotary kiln designs both our innovative rotax2 and our traditional 3base kilns help ensure optimal quality clinker they deliver maximum operational reliability with low operating costs

The eo system was first started up together with abb experts at adana cement on 11 may 2009 for process optimisation of clinker production line 4 which has an average capacity of 4500 tpd including the control of the rotary kiln calciner and clinker cooler in a second step the raw mill of line 4 and coal mill 2 were included in the eo system

Figure 2 2200mtpd kiln powered by a 350hp single drive a second variation of the clinker process is the long dry kiln there are many of these around typically a technology of the mid sixties and seventies the main difference is that the raw mix is dry to begin with the kiln is somewhat shorter and the diameter of the kiln is usually smaller
