Jan 16, 2013· Fell et al. selected 119 cement mill workers, from them only 19 were non smokers; remaining all were either smokers or exsmokers. They selected the control group from an ammonia producing industry. They compared the lung function parameters of cement mill workers with a control group of subjects employed in ammonia industry.
The resulting clinker (rounded nodules between 1mm and 25mm across) is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality .
Feb 10, 2016· gather as much information regarding the actual operation of this mill during cement grinding and the quality of the product in terms of the fineness/particle size distribution and how does it compare with the product of a ball mill relative to these parameters. Other parameters(VRM vs. Ball Mill) to be considered are the following:
Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.
developed to model relationship among cement mill operational parameters. The response variable was weight percentage of product residue on 32micrometer sieve (or fineness), while the input parameters were revolution percent, falofon percentage, and the elevator amperage (amps), which exhibits elevator charge to the separator.

An increase in clinker AR (also sometimes written as A/F) means there will be proportionally more aluminate and less ferrite in the clinker. In ordinary Portland cement clinker, the AR is usually between 1 and 4. The above three parameters are those most commonly used.
justify this, retarder raw materials are used. In cement industry, natural gypsum (CaSO 4 ·2H 2 O) is the most effective raw material for this purpose. In the natural gypsum sources, anhydrite gypsum can often be encountered, so its effect on cement''s quality parameters must be focused on [13].
