In cement industries, grate coolers are commonly used for heat thermodynamics efficiencies of a cooling system for grate cooler.

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

Abstract and Figures The concept of the exergy analysis is applied to a grate cooler of a cement production facility. The cooling of the clinker is modelled by a gas-solid series of cross-current

the grate cooler was a serious limitation of the simulation research that has been conducted on the process. The cooler . 6 is known ( by the operating personnel) to have a definite effect on the operation of the rotary kiln, but until now, no analysis of this effect has been presented. The analysis of this problem was begun by derivation of a set of mathematical equations to

The Grate, the Kiln and the Cooler. The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed. The Travelling Grate is where pellets are dried and then heated up to a temperature of about 800-900 deg C. The heat used to dry and preheat the pellets is typically hot air pulled

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.

28/11/  · Clinker Cooler. The Air-Quenching shaking grate Clinker Cooler was developed more than 20 years ago as an improved heat recuperating cooler for use with rotary kilns. It was designed to air quench and cool large quantities of hot clinker rapidly, and to recover and return to the kiln a major portion of the heat from the clinker.

KEYWORDS: IMC based PID controller, grate cooler, Under Grate Pressure (UGP), kiln. I. INTRODUCTION. In grate coolers, in order to provide proper cooling of 

moves slowly on grate bed. Cooling air blows into the clinker layer vertically from the bottom of the clinker, permeates and diffuses in the clinker to cool the red-hot clinker. Cooling air becomes hot air after exchanging heat energy with clinker. Fig. 1: The schematic diagram of grate cooler Fig. 2: Physical model of grate cooler

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
