: ATOX® raw mill February 26, 2013 This film demonstrates all aspects of the ATOX® raw mill: how it saves space and energy and why it has been proven to deliver reliable operation for crushing and grinding all types of raw materials, coal and pet coke.
About 85% of the total energy expended in cement production is used for size reduction; 75 % in grinding operation alone and 2 - 20 % of the energy supplied to the mill is used for size reduction, the remaining is lost in various activities such as friction between particles, friction between particles and mill elements, generation of heat and sound, vibration and material turbulence etc.
The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm).
It is interesting to note that when James Parker commenced making his Roman Cement, he set up at Northfleet, not for reasons of raw materials or market, but because a water mill was available. In the cement industry context, this technology was difficult to apply because the grinding stones consisted usually of fine-grained sandstones not much harder if at all than the minerals

The main constituent of cement, is lime and limestone, the main raw material for them.so The cement is a combination of Calcium oxide (lime) with other oxides such as aluminum oxide, silicon oxide, iron oxide, magnesium oxide and alkaline oxides that have affinity for combining with water in the air and under water, and the resistance is slightly hard.
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw
The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires (26 MJ/kg calorific heat) and 290,000 t of industrial waste (plastic waste, paper, textiles, etc., 22 MJ/kg caloric heat) (VDZ, 1999).Table VI.5.21 shows a comparison of components of traditional fuels and scrap tires.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
