Clinker free lime (CaO f) should be as high as possible to avoid hard burning of clinker, but safely below value, inviting mortar expansion; normally, between 0.5% and 1.5%. Free lime indicates incomplete clinker burning, therefore should be monitored regularly and maintained closely in the acceptable range.

Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
It is a fine powder produced by grinding Portland cement clinker (the solid material produced by the cement kiln stage that has sintered into lumps or nodules, typically of diameter 1-25 mm) (more than 90%), a maximum of about 5% gypsum which controls the set time, and up to 5% minor constituents (as allowed by various standards).

crushers, grinding clinker coolers and material handling equipments. The case study suggests that the major sources of CO2 emissions are from the fuel burning and during the clinker production in kiln, which forms a part of the cement production process itself. The study found that 0.613 ton of CO2 is emitted when one ton of clinker's produced.
It is generally added in very small amounts (about 2% by weight) to the burnt cement (called Clinker) after it is taken out from the kiln and before it is sent for grinding. Gypsum is a sedimentary rock having a composition of calcium sulfate (Ca SO 4 . 2 H 2 O).
The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller. The crushed rock is combined with other ingredients such as iron ore or fly ash and ground, mixed, and fed to a cement kiln. ... The remaining elements unite to form a new substance called clinker. Clinker comes out of the kiln as grey balls ...

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.
Clinker is anhydrous (without water) having come from a hot kiln. Cement powder is also anhydrous if we ignore the small amount of water in any gypsum added at the clinker grinding stage. The reaction with water is termed "hydration". This involves many different reactions, often occurring at the same time.

The resistance to grinding was expressed as a constant parameter (K R) in the model proposed by Rittinger for grinding fine particles and was found to be 56, 40 and 14 J mm/cm 3 for clinker, gypsum and limestone, respectively.
This chemical reaction occurs at high temperature in a rotary kiln, grinding the cement clinker nodules to passing 90 microns in a dry circuit. fGrinding occurs at the beginning and the end of the cement making process. Approximately 1.5 tonnes of raw materials are required to produce 1 tonne of finished cement.

grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The

The emphasis placed upon grinding temperatures is associated with the effect that this has upon the calcium sulfate (gypsum rock) added to the clinker, in amounts normally between 3 and 8 per cent, to retard the hydration of the tricalcium aluminate and to optimise the strength-giving properties of the calcium silicates.
The pyro processing of kiln feed produces cement clinkers. The hot clinkers are then cooled down and bucketed to store in clinker stockpiles. After this stage, the clinker and gypsum are mixed together and sent to the mill inlet for the further grinding process to form a fine grey powder.
