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.
As one of the key equipment of clinker firing systems in cement production, the main role of grate coolers is to cool and convey cement clinker. At the same time, the grate cooler can also provide hot air for rotary kilns and decomposition furnaces, etc., to realize the recycling of heat energy.
Clinker Cooler. The hot clinker produced by the rotary kiln is transferred to a grate cooler, where it is cooled by air blowers before being taken by conveyor belt to the cement mill. …
The grate cooler in a cement plant cools and transports the cement clinker from the rotary kiln, and provides heating air (secondary air) for the rotary kiln and preheater. The performance of the grate cooler will directly affect the production efficiency, energy consumption, and clinker quality of the kiln system.
In cement plants clinker outlet temperature is directly evaluated by clinker cooler process efficiency. ... Therefore, for proper cooling (below 200 °C), there should be an efficient heat exchange between clinker and air which is produced by cooler fans. This is, in addition, maintaining high rate recovery of heat to secondary air, tertiary ...
The latest type of rotary cooler can cool the fresh cement clinker to 150 ~ 250 ℃ and provide secondary air at 700 ~ 800 ℃ for the rotary kiln. Its overall thermal efficiency can reach 55% ~ 70%. Structure Design Rotary cooler structure design. The main body of a rotary cooler is a rotary drum cylinder which is set at a slight horizontal slope.
The grate cooler is a quenching type cement cooler applied for the cement manufacturing plant. According to the movement mode of the grate, the grate cooler can be divided into three types, rotary type, vibrating type, and push-type grate cooler, with the development of cooler technology, push-type grate cooler is considered the most common clinker …

Based on years of research, development and operational experience, it combines simple installation and low maintenance with advanced design to give you efficient clinker cooling and low operating costs, however …
The coolers in practice were almost useless. Masons, using them up to the 1960s, recorded clinker outlet temperature around 1000°C, and the "quenching" of the clinker, necessary for good quality, was delayed until it fell out onto the conveyor.. A modest improvement in performance could be obtained by fitting a "van der Werp" cooler. This …
Magotteaux and the Clinker Cooler. A clinker cooler is a major element of manufacturing clinker. Ground raw meal made from limestone is turned into clinker within a rotary kiln. The raw materials (clay, limestone, and some minor additives) are ground and blended in a raw mill. At this point, the mixture is called raw meal. When cement clinker ...
