Jan 15, 2016 SNOWMAN FORMATION IN COOLER 01/15/16 10 Why snowman is formed in cooler? Main reasons- Higher % of liquid, may be iron % is more in raw mix so hot meal will be sticky and viscous.Shorter cooling zone; so may be shortage of adequate quenching .Higher BZ temperature, may be due to short flame.Failure of air blaster in cooler 1st grate if any.
Jul 04, 2020 15 Cement Storage Silo .The cement storage silo is used for storing the finished product - cement.The cement is packed with the help of a rotary packer and finally dispatched to the market.17 Central Control Room It is the nerve center of the cement plant since all equipment is controlled from this place.

Mar 01, 2005 Cement production has been one of the most energy intensive industries in the world.In order to produce clinker, rotary kilns are widely used in cement plants.This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey.The kiln has a capacity of 600 ton-clinker per day.
Mar 21, 2013 The principle on which the air-cooler works is as follows- Water, when evaporates it needs heat called 'latent heat of evaporation'.In the cooler the water that is sprayed over the pads when evaporates takes the required latent heat from the atmospheric air surrounding them which on losing its heat cools down.
May 11, 2015 • The modern Indian cement plants are state-of-the-art plants and amongst the best in the world.In order to meet the expanding demand, cement companies are fast developing new plants.• Cement plant construction is quite a specific construction and it requires high quality and precision with adequate safety.

Objective of this paper is development of first principle based model of grate cooler for cement plant.In this work, the temperature variation and assumptions of the model will be discussed.The model is developed for steady state condition.Variations of gas, solid temperature, wall temperature and heat losses through the wall are simulated with respect to grate cooler length.
Oct 08, 2020 IKN clinker coolers have one movable row of Coanda Wing plates followed by two fixed rows.The forward movement of the grate is accomplished by a hydraulic or mechanical drive system in combination with the LPS (Linear Pendulum Support).
Oct 22, 2015 The Grate cooler operates with crosscurrent principle in which the clinker is moved across the grate while cooling air blow in from below through the grate and clinker layer.The hot clinker falls from the kilin and forms clinker bed on the grate and transported through the cooler over fixed and reciprocating grates.
Rotary Cooler (lime cooler, cement cooler, magnesium cooler) work principle: Cooler is widely used in building material, chemical industry, metallurgy, and other industry, matching with rotary kiln.The equipment in the natural state, low speed revolving in a slope of 3.5%, the material feeding from the top of cylinder, scatter plate is .

Sep 01, 2019 The cement plant, located in Baishan City, Jilin Province, was equipped with new dry process clinker production line, and the production capacity was 3800 tons per day.1, the field measurements was conducted in the flue gas from the preheater and the hot air out from the clinker cooler.
Specifically for cement applications.With more than 40 years of plant automation experience, FLSmidth has installed over 700 control systems and 450 laboratory systems – and understands the needs of today’s cement plants.
The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation.Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110 C – 120 C, cooling to below 80 C is necessary to avoid this reaction.
The grate cooler in a cement plant High quenching speed has the following advantages: 1) prevents the clinker from pulverizing due to C 2 S transformation; 2) makes the clinker ball produce internal stress and improves its grindability; 3) reduces the crystallization of C 3 A in clinker and improves the sulphuric acid resistance of finished cement.
The refrigeration cycle is based on the long known physical principle that a liquid expanding into a gas extracts heat from the surrounding substance or area.(You can test this principle by simply wetting your finger and holding it up.It immediately begins to feel cooler than the others, particularly if exposed to some air movement.
This is an inclined arrangement of specially designed anti spillage Grate plates, arranged in downward steps formation.The Castable cover is shaped in such a way to have spread of hot clinker on grate without void.
