  • Cement Kilns Design features of rotary kilns

    A typical long-term-mean refractory consumption of a wet process kiln would be in the range 1-2 kg per tonne of clinker made so the refractory was still a significant running cost. With the advent of more efficient dry processes and particularly precalciners the relative cost of refractories has been reduced mainly because of the larger
