Providing information for people working in cement plants, those who want to improve the way they work.

The cement clinker leaving the kiln consists of hard granular particles ranging from 1/8 inch to several inches in diameter. This clinker is transported through a cooler (Figure 1) on a moving grate while a controlled stream of air passes through the bed of clinker. The heated air from the cooler is then used for burning the fuel in the kiln.

As the clinker passes under the flame it starts to cool and the molten C 3 A and C 4 AF, which constitute the flux phase, crystallize. This crystallization is normally complete by the time the clinker exits the rotary kiln and enters the cooler at a temperature of ~ 1200 °C.

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.

Uses: The grate cooler is an important main equipment in the clinker burning system of the cement plant. Its main function is to cool and transport the cement clinker. At the same time, it provides hot air for the rotary kiln and the decomposition furnace, which is the heat recovery of the firing system. The main equipment.

Finally, the cement clinker cooler cools the high temperature clinker discharged from the rotary kiln to the temperature that the downstream transportation, storage and cement grinding can bear. At the same time, the sensible heat of high-temperature clinker is recovered to improve the thermal efficiency and clinker quality of the system.

Cement kiln feed becomes clinker after being sintered in the rotary kiln.Then it must be cooled — this is where the clinker cooler comes in. Clinker coolers bring the product to ambient temperature for the grinding process and recover heat from the clinker that is useful for combustion.

ENERGY MODELING OF THE PYROPROCESSING OF CLINKER IN A ROTARY CEMENT KILN. This paper highlights the efforts taken by the author in developing an Energy Model for the pyro-processing of Clinker production in a dry-process rotary cement kiln. In this paper this Energy Model is applied to a state of the art cement plant in a Far East Asian country.

To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air.

Rotary cooler is also called clinker cooler, which is the important support equipment of cement rotary kiln.It is mainly used to cool the high-temperature clinker（1000-1200℃）discharged from the rotary kiln into an appropriate temperature (less than 200℃).

Rotary cooler is one kind of cement cooler applied for cement manufacturing plants.As an essential part of the cement kiln system, a rotary cooler is used to cool the clinker discharged from the cement rotary kiln.The rotary cooler also helps air to absorb the large amounts of heat carried by clinker, heating the combustion air up to the high temperature, strengthen the calcination, and reduce ...

The clinker cooler, also known as grate cooler or cement cooler, it is a necessary equipment of cement clinker production.The clinker cooler is mainly used to cool and transport the cement clinker. At the same time, cement cooler also provide hot-air for rotary kiln and calciner, it is the main equipment of heat recovery for burning system.

The hot clinker discharged from the kiln at a temperature of about 1300 C is further treated in clinker cooler. The cooling of clinker influences its structure, main composition, grindability and consequently, the quality of the resulting cement. ... Rotary or Shaft coolers in which all the cooling air has to be used as combustion air supplied ...

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.

Rotary and planetary coolers operate under suction and although noisy, produce little atmospheric pollution. The waste air of a grate cooler naturally contains a large amount of gritty clinker dust. The early coolers, like the kilns, made little effort to trap this, …

Clinker cooler. The hot solids from the kiln are discharged on the grate of clinker cooler. As the grate moves with uniform speed along the cooler length, solids lose their heat to cross-flow air. A part of the air is generally sent to the kiln as secondary air, a part to calciner as tertiary air and a part is vented to the surroundings (vent air).

Rotary coolers are a type of traditional cooling equipment in cement plants. They perform especially well on cement clinker cooling in small-scale clinker production lines and mini cement plants.. As a top cement equipment manufacturer in China, AGICO has successfully designed and set up several rotary cooler projects in domestic cement plants and earned a good reputation in the industry.

Innovative development of grate cooler technology. This new cooler combines the best solutions for each of the two fundamental, mutually interacting functions a clinker cooler has to accomplish: Clinker conveying is based on the "moving floor" principle; Aeration is controlled by self-regulating valves

In the cooler the air is heated by the cooling clinker, so that it may be 400 to 800 °C before it enters the kiln, thus causing intense and rapid combustion of the fuel. The earliest successful rotary kilns were developed in Pennsylvania around 1890, based on a design by Frederick Ransome, [5] and were about 1.5 m in diameter and 15 m in length.
