how how is clinker turned into powered cement

cement from clinker - Engineers India Research Institute

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.

The lime is used to produce clinker, while the CO2 is released into the atmosphere. Decarbonising this part of the cement production process is tricky, but there are two approaches that can be taken. One is to reduce the quantity of clinker in cement by replacing it with something else. The other is to capture the carbon released from calcination.
