They are mixed either dry (dry mixing) or by water (wet mixing). 3) Prepared raw mix is fed into the rotary kiln. 4) As the materials pass through the kiln their temperature is rised upto 1300-1600 °C. The process of heating is named as “burning”. The output is known as “clinker” which is 0.15-5 cm in diameter.
