Cement kiln Wikipedia

heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of the rawmix rises: 70 to 110 °C Free water is

Mass Concrete and Materials Used, Properties,

The temperature rise in concrete mass can control by pre-cooling the concrete materials, limiting the amount of heat liberated, and immediate cooling after placement. Pre-cooling the concrete material can lower the maximum temperature but will not substantially change the amount of temperature rise associated with cement hydration. Cooling the coarse and fine aggregate is of greatest benefit

Fire and Explosion Hazards in Cement Manufacturing

Coarse material is returned to the grinding mill and fine particles (raw mix) are blended in homogenizing silos. Homogenization takes places when air entering the bottom of the kiln passes through the raw mix fed from above. Raw mix is heated up to 800C by kiln waste gases in a multi-stage cyclone pre-heater before it enters the kiln. The pre-calciner in lower part of the pre-heater almost
