Rawmill

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Cement Raw Mill in Cement Plant for Cement Raw Meal Grinding

Percentage loss in raw materials,clinker,cement and Coal

Apr 11, 2006 Re: Percentage loss in raw materials,clinker,cement and Coal stocks inventory. This is a tricky question.For efficient operation of the plant the losses in all raw materials should be as low as possible.For inventory purpose companies have got their own policy guideline circulars where they mention say 0.5 to 5% for different types of raw materials which includes fuel oil.

MERCURY IN THE CEMENT INDUSTRY

Mercury emissions are typically higher in kiln operations with the raw mill-off (“direct” operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.
