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 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

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

Grate Cooler. Industrial Clinker Cooler is extensively used to cool the clinker and extracted heat from hot clinker is supplied at secondary and tertiary air to kiln. Acknowledged for its optimum specific grate load, this ensures lower heat consumption. It is basically supplied in two independent entities inlet stationary inclined grate and

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

heat recovery rate in conventional grate coolers are approximately 50 to 60 %, When high temperature clinker is dropped on the grate of cooler from the 

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

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.

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

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.

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

be the number one choice for clinker cooling technology. The initial development of the IKN Pendulum Cooler® started more than 30 years.

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
