The POLYTRACK clinker cooler

feature of this clinker cooler – is very effective: In the direction of conveyance of the clinker transport tracks move to and fro above the static aeration floor The rows of transport tracks are installed at a particular distance to each other Between them the cooling air enters the bed of clinker The required width of the

However incorrect operation would not only lead to the generation of some unexpected phases which are harmful to the clinker performance but also exert a significant influence on the microscopic textures and the crystal characters of the principal clinker minerals Usually rapid cooling is favorable to produce high-quality clinker Cooling

without material in April 2015 The first clinker was cooled only a few days later Operation of the ETA cooler At a specific load of 45 3 t/dm and 1 78 Nm/kg cooling air a cold clinker temperature of 65˚C above ambient temperature is achieved The intensive cooling of the clinker is realised by a long retention time inside the cooler

Clinker Coolers Content Tasks of clinker cooler Theory and definitions Grate coolers Cooler upgrade Clinker crusher Rotary coolers 4 Holcim Group Support Tasks of the Clinker Cooler 1) Recuperation of heat from hot clinker 2) Cooling of clinker Approach to achieve this: Hot clinker is exposed to a stream of cold air for a certain period of

The clinker must be brought in an intensive contact with the cooling air The quantity of available cooling air affects the efficiency The efficiency is not only determined by the machine itself but also by the amount of cooling air The granulometry of the clinker affects the cooling efficiency Rough guideline for the Heat Balance Heat input

Clinker cooler

The novelty of the proposal lies in the fact that MF is t increasing the bore of the drum from loading to unloading i e conditionally conical drum violates the stationarity of the motion of particles increases the intensity of heat cooling the clinker particles and expanding technological capabilities

Diffusion cooling the hot clinker Cooling air after cooling process becomes hot air and the high-temperature hot air is used as combustion air into the kiln and decomposition furnace (pre-decomposition kiln system) and some hot air can also be used for drying and extra hot air will be discharged into the atmosphere after dust-removing

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product Clinker occurs as lumps or nodules usually 3 millimetres (0 12 in) to 25 millimetres (0 98 in) in diameter It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement

Following capacity increases cooling with air alone is often no longer sufficient to achieve the proper operating conditions of the downstream filter Injecting water into the clinker cooler provides a remedy here The cooling of the gas also causes the gas volume to reduce and protects downstream plant components from excessive gas

Upon exiting the kiln the cement clinker is cooled to approximately 80C Gypsum is then added to the composition and the cement clinker is ground down into cement powder ready for storage packaging and transport HOW IS CEMENT COOLED? Cement cooling is an important step in the cement production process as it reduces the chance of gypsum

Wouldn't it be nice: to have no maintenance on the cooler between kiln stops? to have cold clinker all the time? to reduce the kiln heat consumption to a minimum? to have a cooler that has an availability of ? to have a cooler without grate plates hoppers regulation flaps or anything else that can break down? 3

Summary: In the course of the rapid cooler development in recent years new generations of grate coolers have come onto the market In fact it has meanwhile become difficult to keep track of the current cooler generation However despite the new market introductions no great improvements have been made with regard to cooler efficiency and the cooling principle

The invention relates to a cooler for cooling clinker with a device for removal of a sample of the clinker wherein the cooler has a first cooler section a second cooler section and a crusher disposed between them and the device for removal of a sample of the clinker is disposed in a region between the first and the second cooler section

Clinker Cooler for Gas Cooling

Following capacity increases cooling with air alone is often no longer sufficient to achieve the proper operating conditions of the downstream filter Injecting water into the clinker cooler provides a remedy here The cooling of the gas also causes the gas volume to reduce and protects downstream plant components from excessive gas

To achieve this the clinker bed is cooled with a continuous stream of air Pressure monitoring is required in the lower part of the clinker cooler to make the cooling as effective as possible The material height of the hot clinker at over 1000 C on the conveyor belt also has to

03/10/2017Air required to cool 1 kg of clinker Dear sirs I would realy like to know if someone elaborate how to calculate air requirement for cooling 1 kg of clinker Thanks Reply Know the answer to this question? Join the community and register for a

Clinker coolers as the name connotes are used to lower the temperatures of clinkers This is very necessary because the heat from the mill is sometimes capable of damaging the clinker handling equipment The mill temperature heats up the clinkers therefore it is necessary to cool it as much as possible before releasing it to the heat of the

Strictly speaking the cooling of clinker does not only start in the cooling tubes but already in the kiln In the case of a planetary cooler the kiln burner pipe is always inserted into the rotary kiln so that a cooling zone behind the flame of 1 5 to 2 5 kiln diameters is created This zone is called the kiln internal cooling zone and must be considered as an integral part of any planetary

This study analyzed five cooling rates of Portland cement clinker produced in a laboratory Characteristics of clinker minerals were then analyzed with an emphasis on silicate minerals alite and belite The fastest cooled sample was determined to be the best quality sample in terms of hydraulic reactivity Alites and belites in this
