Palm oil clinker (POC) is a residue produced upon burning of palm oil shells and fibres in a boiler of palm oil mill. The aim of this work is to evaluate the high temperature effect on compressive strength and microstructure change of palm oil clinker powder (POCP) containing cement paste.
The cement produced with only clinker had the lowest expansion. In other hand the specimens cured at 80 °C showed: • The expansion of the cement containing gypsum and clinker sulfate had higher expansion than the same cement cured at 20 °C but the tendency of the curves of the expansion were comparable in both case.
The cooled clinker is then conveyed either to the clinker store or directly to the clinker mill. The clinker store is usually capable of holding several weeks' supply of clinker, so that deliveries to customers can be maintained when the kiln is not operating. Get a Better Understanding of Cement
3.5 Properties of the major cement minerals. About 90-95% of a Portland cement is comprised of the four main cement minerals, which are C 3 S, C 2 S, C 3 A, and C 4 AF, with the remainder consisting of calcium sulfate, alkali sulfates, unreacted (free) CaO, MgO, and other minor constituents left over from the clinkering and grinding steps. The ...
Finally by the cement clinker cooler high temperature clinker discharged to rotary kiln cooling to the downstream conveyor, storage library and cement mill can withstand temperature, recovery of high temperature clinker sensible heat at the same time, improve the thermal efficiency of the system and quality of clinker.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
May 11, 2015· a grinding mill which consumes 60-70% of the total electricity consumption of the cement plant[12]. A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and
3.4 Burning in a kiln – formation of cement clinker. The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw mix.

temperature causes the raw material to react and form a hard nodular material called "clinker". Clinker is cooled and ground with approximately 5 percent gypsum and other minor additives to produce Portland cement. The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs.
how does ict help control the clinker milling. optimum clinker temperature for cement mill - control over the content of free lime in clinker and help main-tain an optimal value range between 08% and 12%, Saving energy and costs with a monitoring system for kiln inlet gas, a cement mill is wasting excessive energy in forming clinker minerals whose clinker turns out to be too hard
Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, egg-cup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor ...

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.
CEMENT ROTARY KILN Questions & Answers Question-1: What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell? Answer-1: The maximum recommended kiln shell temperature varies by plant, by country and by kiln manufacturer, despite the fact that most kiln shells are made of low alloy carbon steel.
