Cement Kilns: Grate CoolersThe essential characteristic of a grate cooler is a layer of clinker spread on a more-or-less horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air keeps it sufficiently cool to avoid melting or burning. The clinker progresses through the cooler by moving more-or-less horizontally.cement kilns coolers,Cement Kilns: Clinker CoolersCoolers are essential parts of rotary kiln systems. Clinker leaves the kiln at 1200°C or more. Clinker at this temperature has a heat content of 1.22 MJ/kg and must be cooled in order to: avoid wasting this heat energy; obtain clinker at a temperature suitable for grinding - less than 100°C; rapidly cool ("quench") - the clinker,.Kilns/Coolers - International Cement ReviewBrowse all cement industry Kilns/Coolers supplying companies.

Cement kiln - Wikipedia

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 (typically 7–9) of tubes attached to the kiln tube. They have the advantage that they.

Cement Kilns: Rotary Coolers

Sep 5, 2011 . Stokes' Cooler. A rotary cooler consists of a slightly inclined tube of similar construction to a rotary kiln, placed at a lower level than the kiln so that the clinker leaving the kiln can fall directly into the upper end of the cooler. Ambient air enters at the other end. The upper part of the cooler, because of the high.

Clinker cooler POLYTRACK > Cooling > Clinker production .

The POLYTRACK cooler is a combination of a static, horizontal aeration floor and an above-floor material transport system. Its convincing advantages are the very high material transporting efficiency and strict separation of the functions of transportation and aeration, due to: optimum transverse distribution of the material.

Reciprocating coolers | Magotteaux

Reciprocating coolers. Coolers in cement plants are key installations: They allow heat recovery from the clinker back into the kiln and preheater – thus fuel saving. They ensure a final clinker temperature that will allow safe and easy handling/storage. The cooler grates plates should therefore be looked at as strategic.
