Optimizing operating costs to improve profitability in a cement plant The Cement Industry is under increasing pressure to become more profitable Globally there is overcapacity of production To be competitive Production Units need to optimize operations to the maximum possible level so as to lower

cement accounted for 3 of US cement output USGS 2012a Cement plants are typically constructed in areas with substantial raw materials deposits eg 50 years or longer There were 110 operating cement plants in the US in 2010 spread across 37 states and Puerto Rico Portland and blended cement was produced at

Low output on the heat losses per tonne clinker will increase if the system is being run at a lower than optimum output Poor cooler efficiency caused by poor air distribution poor maintenance bad design or a combination of all three It is quite common for coolers to be operating at between 5 and 10 below their maximum efficiency

Source Hodlerbank 1993 Present and Future Use of Energy in the Cement and Concrete Industries in Canada Three dry process kilns have also been shut down during the decade but average kiln capacity has increased by 34 percent further contributing to gains in energy efficiency

Cement kilns are thermal equipment used to produce cement clinker Generally there are two types of vertical kilns and rotary characteristics of the vertical kiln are simple equipment low investment and high thermal efficiency but the quality of the calcined clinker is not stable enough and the production capacity is is generally used in small cement plants

Though the rotary kiln has now firmly established itself as the most economical and efficient form of mechanism for the production of Portland Cement many of the old stationary kilns both of the intermittent and continuous varieties are still in constant use in Europe nor is their product in any way inferior to that produced by the modern method
