The essential function of grate coolers is a waste heat recovery from hot clinker which leaves the rotary kiln This paper presents an analysis of energy and exergy based on the clinker
Clinker Cooler After cement is dried by being put through a rotary kiln and converted to clinker it needs to be cooled Cooling tunnels are used to reduce the temperature of the clinker from over 2000F to a workable 200F These tunnels typically use forced draft fans to push the cooled air through the clinker
To save energy modern cement plants preheat the meal before it enters the kiln Rising more than 350 feet hot exit gases from the kiln and clinker cooler bined with fuels such as ground coal petcoke natural gas and recycled waste streams heat the raw materials as they swirl through the cyclones
Lowcement castables including Kricon 3270 QuikTurn 3270 and the RMax product family offer exceptional service for the castable nose ring Cement clinker is discharged from the kiln into the clinker cooler The clinker is moved from the cooler inlet to the discharge by the reciprocating motion of perforated grates
The clinker discharged from the rotary kiln enters the rotary cooler and is rapidly quenched with water from 1400C to 600C The clinker subsequently passes through the roll crusher which produces grain sizes 50 mm Finish cooling from 600C to the ultimate temperature of approx 100C is performed on the vibrating grate with air

Aug 09 2018RING BUILDUPS IN KILN SECTION PART1 The rings and buildups are accumulations of solid materials in the rotary or static sections of the kiln Ring and buildup formation in cement kilns and preheaters has very bad influence on cement manufacturing process Decrease or stopping the clinker production there by increasing the production costs
Process Coolers for Cement Clinker Clinker cooler with Coanda Wing technology Following the stationary inlet KIDS the cooler is divided into separately aerated partments The main features of the clinker cooler with Coanda Wing grate plates are Stabilised kiln and cooler operation Download Brochure Latest News Visit us
However output of this latter line was being limited to 3400ptd because of the inappropriate design of the clinker cooler mechanics which caused bottlenecks High cooler loss and heavy mechanical failures resulted in unplanned kiln stoppages The inefficient cooler process meant the line was operating with a high outlet and vent air temperatures
Typically kiln feed used to make cement clinker enters the cooler at 1400C and cools to about 150C as it travels to the outlet Because the service environment is very abrasive and subject to thermal shock on a regular basis HarbisonWalker Internationals products are focused mainly on abrasion resistance
Obtain the cement clinker It involves the preheating of raw materials calcination clinker reactions and cooling of the clinker These steps take place in the kiln system which consists of a preheater tower a calciner a rotary kiln and a clinker cooler A typical modern kiln system is
Red River in Cement Grate Cooler Red river is a phenomenon in grate cooler it is often a red hot narrow stream of fine clinker with a higher temperature than the neighbored clinker and appears far down in the cooler
The Cement Plant Operations Handbook SEVENTH EDITION The Cement Plant Operations Handbook is a concise practical guide to cement manufacturing and is the standard reference used by plant operations personnel worldwide
Dec 08 20101 A large amount of fines are present at the kiln outlet 2 Large lumps of clinker coating fall from the kiln onto the first grates of the cooler 3 High temperatures andor high amounts of liquid phase is present in the clinker exiting the kiln
Manufacturing the cement kiln Most Portland cement is made in a rotary kiln Basically this is a long cylinder rotating about its axis once every minute or two The axis is inclined at a slight angle the end with the burner being lower

Maximum possible clinker cooling using the lowest possible cooling air volumes it is necessary for the clinker to remain in the cooler for a particular length of time and for the cooler to achieve the best possible distribution of clinker and cooling air The hot clinker from kiln are discharged in the grate cooler at
Wet process cement kiln the cement raw material is grinded with water powder into raw slurry 3340 water and then fed into the wet process rotary kiln and burn into cement clinker dry process cement kiln the cement raw materials are dried ground and calcined into the cement clinker in the dry process rotary kiln
The core of the entire cement producing process the clinker formation the rotary kiln in Thus in order to maintain or even improve clinker quality and we need a better understanding of output the development of clinker properties inside the kiln to react upon the impact of process changes
Much like the rotary kilns that feed them clinker coolers are subject to extremely high operating temperatures and dust levels Bearings on the cooler grates have to operate at low speeds under moderate to high loads
TY BOOK T1 Cofiring of Alternative Fuels in Cement Kiln Burners AU Pedersen Morten Nedergaard PY 2018 Y1 2018 N2 The production of cement is an energy intensive process where traditionally 30 of operating costs have been related to fuels
The clinker cooler is an essential element in the production of cement The cooler as the name implies cools the clinker to manageable levels while transporting it away from the kiln It also recovers heat from the clinker for use in the kiln precalciner and other areas In addition the cooler sizes the clinker breaking up large pieces
