Keeping kiln shell temperatures under control Cement
Above Table 1: Example calculation of the costs of production loss due to an unplanned kiln stop, assuming two days for stop/cool down, two days to work on the refractories, one day for drying and one day for startup. This simple calculation already shows the steep increase in the cost of production loss when simply replacing the 4000t/day by higher production rates like 10,000t/day or more.Get Price
