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 is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The process out clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by this process known as Portland cement. The cement manufacturing is done by majorly by two methods known as wet process and dry process depending on their mixing is done with water or without water.

The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

Cement Plant: The Manufacturing Process 1 Limestone (CaCO3) is taken from a quarry 2 4 3 The limestone is fed into a crusher and then stored until needed The clinker is mixed with additives, such as gypsum, and then ground in a cement mill, which creates cement The cement is then packed and distributed to consumers ...
Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum .
cement process, it is important to adjust the grinding plant in order to minimize energy losses. 4 It is essential to use a process automation system to optimize the mill process, which in turn minimizes energy consumption. The raw material is finally transported to the homogenization silo. Clinker production 5
Comparison between wet and dry process Wet process Dry process 1 Moisture content of the slurry is 3550% 1 Moisture content of the pellets is 12% 2 Size of the kiln needed to manufacture the cement is bigger 2 Size of the kiln needed to manufacture the cement is smaller 3 The amount of heat required is higher, so the required fuel
Chapter3 Cement Manufacturing Process 37 the negative air is vented out to the atmosphere. The collected fine powder is retrieved with the help of rapping mechanism and the same is fed to the process. Blending and Storage After filling the powdered materials from raw mill to a certain level in the
Dehydration of the gypsum added to the cement In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process.
In cement grinding the mill ventilation system fulfils two important functions, cooling the cement and removing the heat generated during the grinding process, and carrying part of the finished product out of the grinding area. It is well known that the energy used during the grinding process in ball mills is almost entirely converted into heat.
Chapter 3 provides an overview of the cement production process and an overview of main environmental matters in the cement industry. It describes the main subprocesses involved in cement production and defines the group of subprocesses which is to be covered by the BAT Reference Document for the cement sector.
