Control To The Dust Formed At Grinding Of Clinker And Grinding Cooling In Cement Industry

Clinker Production - Clinker Manufacturing | Cement ...

Step 2: clinker sintering. Clinker sintering is a crucial link in clinker calcination, which mainly occurs in the cement kiln. Inside the kiln, raw meals are heated by rising temperature and generate a series of physical and chemical reactions. When the temperature reaches its peak, the clinker will be produced by rapid cooling.

TEMPERATURE MEASUREMENTS IN

The cool clinker is milled to form a fine powder, and any additional cement components – for example, calcium sulphate to control the setting time – are added. The finished cement is bagged and shipped. 2. 4. 5. Portland cement reacts with water to set, forming a hard, water-resistant substance with similar properties to the original limestone.
