Raw material preparation. From the quarry to raw meal feeding ...
Depending on its characteristics, the raw material needed for the cement production process is quarried by blasting, hydraulic excavators or ripping. A wide range of crushing plants – depending on the material’s properties and type of extraction – can be used for breaking the extracted raw material to the size required by the raw mill.
Raw meal to clinker ratio - International Cement Review
Re: Raw meal to clinker ratio. The true raw meal to clinker factor is given by: 1/(1 – Loss on ignition of kiln feed). It is normally about 1.55. The major variation from plant to plant arises because of the dust loss from the kiln feed, which varies from kiln to kiln dependent on the collection efficiency of the top stage preheater cyclone.

The cement kiln
The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

The quarried raw material is then transported to the cement plant, using mechanical conveying equipment such as ropeways or belt conveyors, or by vehicles like wagons and trucks. The quarried limestone is normally in the form of big boulders, ranging from a few inches to meters in size.
Cement Raw Mill in Cement Plant for Cement Raw Meal Grinding
Cement raw meal is a mixture of various raw materials before cement calcination. It is a mixture of lime raw material (mainly composed of calcium carbonate), clay raw material (aluminosilicate containing alkali and alkali soil) and a small amount of calibration raw material in a certain proportion and ground to a certain fineness.
Vertical Raw Mill for Cement Raw Meal Grinding in Cement Factory
So the vertical raw mill particularly suitable for the grinding of cement raw meal in cement factory. The vertical raw mill in cement industry has been applied in the field of medicine and food because of its high grinding efficiency, can dry up to 10% moisture materials and energy saving of 20% – 30% compared with ball mill of the same scale.
Re: Raw meal to clinker ratio - Page 2 of 5
In a kiln which is being fed with raw meal at 350t/h and has a 'raw meal to clinker ratio' of 1.55 (calculated without respect to bypass), the actual amount of clinker produced with say 10t/h bypass dust removal will be;-(350 / 1.55) - 10 = 215.8t. Therefore the 'raw meal to clinker factor' ,allowing for removal of this bypass dust, will be;-

The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C, where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker, which is the pre-curser for the production of cement.
