significance in the clinker cooling system of cement industry. Unlike the usual process of waste heat recovery, the pipe was inserting within grate cooler to absorb a portion of the heat losses. Fluids such as water, engine oil and ethylene glycol are the fluids of conventional heat transfer and these fluids are widely used in diverse applications in the industry. It is well known that the
Clinker is primarily used to produce cement. Since it can be stored in dry condition for several months without noticeable deterioration, it is traded internationally in large amounts. Cement manufacturers buy clinker for their cement plants in areas where raw materials for cement are scarce or unavailable.

What is Cement Clinker? Composition, Types amp; Uses Civil Engineering
This hot clinker is received at the cooler primarily for cooling purposes through the rotary kiln exit to meet some physicochemical properties (, 2006; Jiang and Cang, 2008). The grate cooler in the cement industry utilize highly powerful fans which adds up to the huge initial capital investment (Hongyou et al., 2009). In fact, the
10/7/2020#0183;#32;In every cement plant, the cooler operation has a crucial impact on operating performance, clinker quality and overall productivity. The development of clinker coolers in recent times has been guided by market demands for maximised availability, reduced maintenance and rapid conversion with minimum production downtime, accompanied by the overarching requirements to reduce energy
Early systems used rotary coolers, which were rotating cylinders similar to the kiln, into which the hot clinker dropped. The combustion air was drawn up through the cooler as the clinker moved down, cascading through the air stream. In the 1920s, satellite coolers became common and remained in use until recently. These consist of a set
Development of Calciner have been a great boon in multiple ways to Cement Industry like: Burning is more uniform and hence clinker produced is also uniform in quality. Raw meal need not be ground as fine as require for kilns carrying calcination duty.
Clinker cooling is necessary because. 1. Hot clinker is difficult to convey. 2. Hot clinker has a negative effect on the grinding process. 3. Reclaimed heat content of the hot clinker is an important factor in lowering the production cost. 4. Proper cooling improves the quality of cement.
In order to improve the efficiencies of the clinker cooler used in cement industries, one should choose the optimum cooling air, the clinker input rate, the clinker bed depth, the clinker inlet temperature, the cooler length, the number of openings for air, and the grate speed (Mundhara and Sharma, 2005; Worrell et al., 2008). Worrell et al. (2008)also stated that c ontrolling the distribution
Applications: Cement, silicate products, new building materials, refractory materials, glass ceramics and other production industries. Applicable materials: limestone, cement clinker, bauxite, activated lime, aluminum hydroxide, bentonite, etc. Uses: The grate cooler is an important main equipment in the clinker burning system of the cement plant. Its main function is to cool and transport the cement clinker.
Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills.
High thermal efficiency: our clinker cooler can feed all the air after cooling materials into the cement kiln as secondary circulating air, which improves the thermal efficiency of the cement kiln.
25/11/2020#0183;#32;The grate cooler is one of the most important devices for cement production and heat recovery, as it cools the clinker rapidly and recovers the exhaust air. The working process is as follows: hightemperature clinker from the rotary kiln falls into the grate cooler and continually moves forward carried by the grate plates. The cooling air flows across the moving clinker to cool it down. To
Clinker cooling is one of the important processes in cement production. Improving the cooling effect is not only beneficial to improve the quality and grindability of clinker, reduce the power consumption of the cement mill, but also can reduce the clinker temperature, recover the waste heat, and create favorable conditions for subsequent cement handling, storage, or transportation.
Clinker after cooling in the clinker cooler, is transported by metallic conveyors and stored either in open or covered areas for aging which improves the grinding efficiency in the subsequent operation in the cement mills and increases the mill output rate. The aging of clinker is commonly done for a period not less than 20 days.
Cement industry uses large number of cooling fans usually between 5 to 15 in one clinker line based on the kiln capacity. Cooling fans are used to blow cold air to the cooler and to cool the clinker from 1500oC to 100oC. Cooling kiln protects equipment and facilitates quenching the clinker to ensure the important forms of minerals like C3S, C2S, C3A, C4AF stay in it, so that proper clinker quality is
Grate Cooler Functions Provide a proper clinker cooling rate and improve the quality and grindability of the cement clinker. ( When the clinker... Provide hot air to the rotary kiln as the secondary air and to the preheater as the tertiary air; improve the thermal... Heat the residual hot air for
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400#176;C1500#176;C in the rotary kiln.
Cooler curb is a commonly used name in the cement industry for the lower part of the cooler walls which are at the level and below the clinker bed. This part of the refractory is exposed to high temperatures and abrasion from the hot clinker traveling down the cooler. Effects of grate cooler dynamics on cement process simulation .
