The amount of excess sulfur is expressed in gram SO 3 per 100kg clinker and calculated according to the equation.. E.S = 1000x SO 3 –850x K 2 O – 650x Na 2 O [gram SO 3 /100kg clinker]. The limit on the excess sulfur is given to be in the range of 250 …
Cement Manufacturing Process
The process is accordingly known as the dry process or the wet process of mixing. Dry process (modern technology) In this process, the raw materials are first reduced in size of about 25mm in crushers. A current of dry air is then passed over these dried materials. These materials are then pulverized into fine powder in ball mills and tube mills.
