Grate cooler back-up insulation for cement plants

In cement grate coolers, dense refractory linings backed by insulation materials often results in an unnecessarily heavy construction, which increases fuel expenditure. Furthermore, the lining can be at risk of alkali attacks, which increases maintenance costs.

Cement Kilns: Grate Coolers

The 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.

Clinker Grate Cooler for Cement Plant

In a cement plant, grate cooler is a basic machine in the calcining cement system, its main function is to make the ripe cement material to next system. At the same time, the grate cooler could offer rotary kiln and decomposing furnace hot air flow, which is the main equipment for recycling heat energy in calcining system.

Mass and Energy Balance in Grate Cooler of Cement Plant

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

Cement Kilns: Clinker Coolers

Clinker Coolers. Coolers 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.


S K Gupta / S K Kaul Holtec Consulting Private Ltd., Gurgaon, India. ABSTRACT. In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases. This corresponds to around 70 to 75 MW of thermal energy. This energy can be tapped …

Cement kiln - Wikipedia

The manufacture of cement clinker. This is called clinker. The hot clinker next falls into a cooler which recovers most of its heat, and cools the clinker to around 100 °C, at which temperature it can be conveniently conveyed to storage. The cement kiln system is designed to accomplish these processes .
