The cement manufacturing industry was an EPA New Source Review/Prevention of Significant Deterioration (NSR/PSD) national enforcement initiative in fiscal years 2008-2010 and was continued as a Reducing Air Pollution from the Largest Sources national enforcement initiative for fiscal years 2011-2013.
In cement plants, motors power various machines, such as conveyors, crushers, mills, and fans. The selection of motors—whether AC, DC, synchronous, or asynchronous—depends on the specific requirements of the application, including the need for variable speed control, starting torque, and energy efficiency.
This includes crushing the raw material and transporting the raw material to the factory through conveyors or roads. ... Fires in bag storage areas can spread to adjoining areas in the plant like the cement bagging station, increasing the potential loss of these fires. ...
