Clinker Grinding is the final step in cement production. The cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its ...
The grinding costs of clinker are smaller than this cost difference.

An exemplary process for grinding cement clinker using rollers comprises introducing cement clinker into grinding contact with rollers operative to grind the clinker into particles; and introducing to the clinker and/or rollers, in an amount of 0.001-0.5 percent based on the dry weight of clinker, a binding-densifying agent comprising at least one polymer having an …
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.

A cement clinker grinding plant consists of the following three processes. (1). Raw material process. (2). Clinker burning process. (3). Finish grinding process. The raw material process and the clinker burning process are each classified into the wet process and the dry process.The raw material process and the clinker burning process are each ...
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.
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 …
Spain: Cementos Cosmos plans to scale down the production of clinker at its Córdoba cement plant as a result as the high cost of electricity. The Cordoba Day newspaper has reported that parent company Votorantim Cimentos said that clinker grinding operations at the site will continue to ensure a sufficient cement supply in the region.
Cement mill is the equipment used in the raw material grinding and clinker grinding process. Its main function is to grind raw meal and cement clinker into an appropriate size to meet the qualified fineness.

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.
Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.
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
Grinding of clinker, together with additions of approximately 5 percent gypsum to control the setting properties of the cement can be done in ball mills, ball mills in combination with roller presses, roller mills, or roller presses.
and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.
