A grate cooler can be regarded as a simple heat exchanger through which the clinker passes across or counter to the cooling air flow and a direct heat transfer takes place between the hot clinker and the cold cooling air. The desired maximum recuperation of the heat from the clinker cooler for use in the kiln system for specific quantities of secondary and tertiary air demands

Extensively, the grate coolers are used in cement industry in order to recover heat This work focuses on the thermal performance of the clinker cooling.

The invention relates to a grate cooler, in which the drive device is surrounded by a drive housing, the inner space of which is sealed in an airtight manner in relation to the atmosphere, but on the other hand has a pressure-equalisation connection to the inner space of the cooler housing. Such a grate cooler is characterised by considerably reduced expenditure for sealing

The grate upgrade kit of the polytrack® clinker cooler was designed specifically to address issues which are gaining importance for cement.

The concept of the exergy analysis is applied to a grate cooler of a cement production facility. The cooling of the clinker is.

The transport speed of the second grate is higher compared to that of the first one due to the smaller grate width of 6.8m. At the end of this second grate the maximum clinker temperature is at 65°C above ambient CHINESE COOLER PROJECTS With an annual cement consumption of about 1.85bnt, China is by far the world´s largest cement market.

The grate cooler heat radiation was measured using infrared thermometer (561-566 nanometer wavelength). This compared the surface temperature to the surface area and values obtained were tabulated on Table 3.3. 3.2 Calculation Basis for Mass and Heat Balances. Basis for material: one (1) kg and 0℃ of clinker is usually taken as the basis. 3.2.1 Cooler Mass and

cooler grates MAGOTTEAUXhas developed new alloys and designs that offer great benefits to conventional coolers, by enhancing both product performance and lifetime. Wear and thus performance of the cooler grate plates depend to a large extent on their location in the cooler.

The cooler loading is defined as the amount of clinker over the grate area. 2.4.4 Cooler Efficiency The efficiency of a cooler is defined as the relationship between the recuperated heat to the kiln and the total heat transferred to the cooler as presented in equation 2.1.

The grate cooler belongs to the family of air quench cooler (AQC). The clinker fed into the grate cooler can be quenched from 1300-1400 ℃ to below 100 ℃ in just a few minutes. The grate cooler can be further divided into three types: the rotary grate cooler, the traveling grate cooler, and the reciprocating grate cooler.

In modern cement plants, the clinker cooler is the key to high recuperation effi ciency and low clinker outlet temperatures at the lowest possible energy consumption. + Compact design + Low power consumption + Effi cient clinker cooling The Pendulum Cooler® is designed as single grate with a roll crusher at the end or as double grate with

The cooler efficiency was found to be. (75.53%) at this stage of the clinker production process. This study revealed that the grate cooler 

company cross grate cooler is mainly composed of 10 working procedures, which are as follows: pre- assembly, welding, painting, installation of driving guide rail, assembly, installation of vents,

coming out of rotary kilns. Heat transfer in coolers indirectly controls the performance of the rotary kiln and is therefore crucial in a cement industry. In this report, we present a computational model to capture heat transfer in grate coolers. The schematic of grate cooler considered in the present study is shown in Figure 2.

20/02/  · The grate drive is located outside the cooler housing, protected from contamination by clinker dust and with improved accessibility for maintenance. Depending on the size of the cooler either a single drive or a synchronized twin drive is installed. IKN grate drives are available as hydraulic or electro-mechanical drive system (DLD-Dynamic

Replacing worn grates or carrying out gap management on grate type coolers are time-consuming exercises and an on-going expense. In the Cross-Bar® cooler, clinker is moved through the cooler using horizontal bars that operate in a shuttle motion across a number of lanes. This effectively conveys, mixes and shears the

The grate cooler is integral to heat recovery from the clinker, so grate coolers that operate with higher efficiencies will lead to less wasted heat and 

the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1 . All these airflows have to be adjusted and controlled as.

The grate of this grate cooler comprises a plurality of stationary and movable grate plate carrier beams on which a plurality of grate plates provided with cooling air bores are secured. The
