There are 3 cement mills A, B and C mill with a clinker grinding capacity of 60 tph for A mill and 50 tph each for B mill and C mill. The B and C mills are identical in construction. A mill has got 2 chambers and for B & C mills 3 chambers each. Flint pebbles of different sizes are used as grinding media. The mills are lined with Felcite blocks.
In the cement mill the material is converted into fine powder. This is where cement is manufactured. The fineness of cement depends on the Blaine. The capacity of cement mill depends on the capacity of the plant such that if the capacity of the plant is 800 TPD then the capacity of the mill will be 800/20 = 40TPH.
Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor
Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

A process for forming cement clinker using mill scale that may have hydrocarbons associated therewith. Normal feedstock material is preheated and then transferred to a combustion area. The mill scale is also transferred to the combustion area where, during the process of burning a material, the unwanted hydrocarbons are volatilized and converted to harmless gaseous …
Drum Mill TM 500. The Drum Mill TM 500 is a laboratory ball mill designed to grind large sample volumes up to 35 l. It accepts initial feed sizes of up to 20 mm and can achieve grind sizes down to 15 µm by friction and impact. Hard, brittle or fibrous samples are pulverized in the 150 l drum filled with 80 kg grinding balls.

The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be 15% lower than that of …
Fig. 3. cement mill section in dry process It is important to note that the strength properties of cement are considerably influenced by the cooling rate of the clinker. The rate of cooling influences the degree of crystallization, the size of the crystal and the number of amorphous materials present in the clinker.
After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.
consumption of mill section. 3.4 Recommendations ♦ Maintain uniform/consistent quality of feed as far as possible to mill by optimising the kiln and cooler operations ♦ Reduce the quantity of grinding media of 100mm size by 50% and increase the quantity of 80mm and 70 mm grinding media to improve the efficiency of Chamber I ...
Clinker litre weight (grams/litre): A convenient supplement for free lime measurement is the more rapid determination of litre weight of clinker sample from the cooler discharge to approximately +6/-12 mm and weighing a standard 1 litre volume. Normal range of litre-weight is 1100-1300 g/L. Low litre weight means high free lime and dusty ...

Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce high-quality clinker, the fineness of coal fines should be controlled at about 12%, and its moisture content should be controlled within 1.0%. The machines that are usually used to dry the coal fines are rotary dryers.
