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.

The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker …

The range of clinker composition may be fairly wide if the amount of liquid phase increases slowlyC~s). A clinker with about 25% liquid phase from a raw-mix is generally considered an ideal raw-mix for kiln lining, fuel saving, rapid C3S formation through the dissolution of CIS and CaO, and economical clinker grinding.

The device has been used for wet and dry fine grinding and for dispersion. Generally speaking, the device grinds materal thousands of times faster than a ball mill. It has shown that for the fine grinding of materials such as cement clinker, the Cyclomill saves over half of the grinding energy currently required by standard ball mills.

Low Heat Cement – IS 12600: 1989 Formation of cracks in large body of concrete due to heat of hydration has focussed the attention of the concrete which produces less heat, at a low rate during the hydration process.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

Multi-compartment ball mills and air separators have been the main process equipments in clinker grinding circuits in the last 100 years. They are used in grinding of cement raw materials (raw meal) (i.e. limestone, clay, iron ore), cement clinker and cement additive materials (i.e. limestone, slag, pozzolan) and coal.
This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production. Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C, in which the chemical transformation occurs inside the kiln to form new compound called clinker.

Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different ...
