Dec 11, 2018· The temperature of cement grinding mills is controlled by a combination of ventilation of the mill by ambient air and water injection into the mill to achieve evaporative cooling. The requirement for water injection depends on the dimensions of the mill and the temperature of the clinker ground in the mill, among other factors.
Clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. The composition of clinker, such as free lime, has to be closely monitored to ensure the quality of the cement.
Nov 02, 2015· High Exit vent temp at cement mill outlet. We have open circuit ball mill grinding OPC 43 grade, feed moisture 2% max, Inlet temp 35 Deg C and outlet temp we are getting around 90 to 95 deg C, what could be the reason of high temp at mill outlet, since we have not supplied hot gas at feed, can anybody suggest the possible reason please, which helps to take necessary action.
At Ebara Fan & Blower Co., Ltd., while communicating with many cement makers, we review the impeller shape and carried out optimum wear-and-tear countermeasures, and provide fans and blowers that have both durability and high efficiency.
1400 °C. The white cement clinker may thus be produced at temperatures lower by about 200 °C below the usual sintering temperature of traditional raw material mixes for white cement. This of course brings about substantial savings in energy not only in the manufacture of white cement clinker, as the method may also be employed in the ...

These materials are blended together, either wet or dry, and fed into a rotary kiln, which fuses the limestone slurry at temperatures ranging from 2,600 to 3,000°F into a material called cement clinker. After it cools, the clinker is pulverized and blended with a small amount of gypsum to control the setting time of the finished cement.
Optimum clinker temperature for cement mill variation of feed chemical composition and its effect on clinker consumption kiln operation clinker formation and cement grinding bed bring about optimum fine grinding and temperature of 90c at the mill outlet by reducing the clinker fuel cement mill cement raw materials handling .
Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
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 clinker grinding in the cement mills is an essential process where the temperature of mill discharge has to be at its optimum value around 90° - 120° C. Engineering services, Cement Mill Water Spray .
Re: Low temperature cement grinding. Hi Gio, Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills, the mill outlet temperature is around 80-85 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution. This will help to increase the strength. Raj. Reply
