Coal in the cement industry
For production of cement the temperature of clinker should be around 1500oC, which can be achieved when flame temperature is maintained at 1700oC. This is achieved by providing preheat to the secondary air. If high moisture coal is used in direct firing system, there may be an excess of moist primary air and required temperature may not be ...

Cement grinding Vertical roller mills versus ball mills
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. It will typically be in the range from 90 to 120 deg. C. At this temperaturelevel the water of crystallisation of the gypsum added to the mill will
Ball Mill Maintenance Installation Procedure
· Where a concrete floor slab is adjacent to the mill foundations, an expansion joint should be used. For convenience in maintenance, the mill foundations should be equipped with jacking piers. These will allow the lifting of one end of the mill by use of jacks in the event maintenance must be carried out under these conditions.

Temperature Conversion Calculator
Calculator Use. Temperature conversions are performed by using a formula, which differs depending on the two temperature scales you are converting between. For example, to convert 50 degrees Celsius (centigrade) to Fahrenheit, we plug our numbers into the formula as shown below: F = C * 9/5 + 32. F = 50 * 9/5 + 32. F = 90 + 32.
Cement
Cement is the main basic ingredient of readymix concrete. Whether in bags or in bulk, CEMEX provides its customers with highquality branded cement products for their construction needs. Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore.
The Cement Manufacturing Process
· There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
Industrial sector Reliable and efficient cement production.
Producing cement reliably and safely while reducing downtime is a continual challenge faced every day. Machines in the cement industry are subject to extreme operating conditions like high contamination, temperatures, vibrations and shock loads. These conditions make maintenance and repair of your machinery a very challenging task.
