The clinker cooler is an essential element in the production of cement. The cooler, as the name implies, cools the clinker to manageable levels while transporting it away from the kiln. It also recovers heat from the clinker for use in the kiln, precalciner and other areas. In addition, the cooler sizes the clinker, breaking up large pieces.

What Is Grate Cooler? A grate cooler, as a quench-type clinker cooler, is the important cement equipment in the clinker calcination system. Its main function is to cool and transport cement clinker. Meanwhile, provide hot air for the cement rotary kiln and precalciner.. There are various types of clinker coolers developed before the grate …

In case of an emergency, such as badly overheated cooler conditions, the kiln operator has two more possibilities to bring the cooler under control: the amount of clinker falling into the cooler can be decreased by slowing tl1e kiln speed, or the temperature of the clinker falling into the cooler can be lowered by adjusting the flame geometry ...

Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller …

The cement clinker manufacturing process is a complex process which involves energy conversion and consumption. The objective of this study is to establish the thermal efficiency analytic model of ...

Clinker in transit to the finish mills should be cooler than 100˚C. It is, however, liable to be at a considerably higher temperature, at least intermittently, at the cooler discharge.

Cooler conditions influence the burning process in the kiln and conse­quently, the quality of the clinker. There are many instances where cooler …

Cooler. Clinker cooler serves two main objective of cooling clinker from temperature of about 1350 0C to the temperature (65-150 0C) where it can be handled by conveyors like pan conveyors, chain, Elevators etc. and heat recovery from hot clinker coming out of kiln. A huge development has happened in clinker coolers designs and types as well.

Raw Materials Crushing, Storing and Grinding. Clinker calcination is the most crucial part of the whole process of cement manufacturing. At this stage, ground raw materials will be sent into the cement kiln and be heated at a high temperature to produce chemical reactions with each other, eventually forming clinker. In addition, clinkers that just …
