Tips for operating cement kilns

data, along with the kiln monitoring equipment, will determine the amount of refractory needed for an outage along with the areas believed to be in need of repair. Once the shutdown begins, the kiln needs a cooling down period of 18 to 30 hours. Cool down time varies with kiln diameters, amount of coating, draft control, and kiln length

    A kiln should be aligned when it is in operation for four very important reasons: 1. A straight cold kiln has a measurable misalignment at operating temperatures. This is because the shell axis elevation increases by one half of the thermal expansion of the shell diameter. This expansion is the function of the shell temperature and, as such, it
