Effect of duration of exposure to cement dust on

Fell et al. selected 119 cement mill workers, from them only 19 were non smokers; remaining all were either smokers or ex-smokers. 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.

Next chapter in the OK™ mill legacy

Product quality is a function of cement particle size distribution (PSD) and the dehydration of the gypsum within the cement. In the OK mill, parameters, such as mill air flow, separator speed and grinding pressure, can be easily adjusted during operation to control or alter the PSD curve to a profile (steeper or flatter) that achieves the ...

CiteSeerX — Effect of Duration of Exposure to Cement Dust on

This is a cross-sectional study of respiratory functions. Spirometry was performed in 100 apparently healthy volunteers; 50 non-smoking cement mill workers and 50 non-smoking un-exposed subjects. Based on the duration of exposure, cement mill workers were divided into three groups, less than 5, 5–10 and greater than 10 years.

Ball Mill Trunnion Bearing Lube System

On a 11’-6” x 22’-0” Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during start-up of the mill. System monitors including pressure switches and flow monitors are provided, along with temperature sensors that monitor ...

Grinding Mills - 911Metallurgist

Ball mills are used for: Grinding materials to any desired fineness. Reduction of large particles. In the cement industry, a ball mill for this application is called a Preliminator mill.

Cement Mill Drives | Transmission (Mechanics) | Engines

Function: A cement mill is a drive 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. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.
