Use of raw materials in the cement industry

The capital-intensive cement industry needs to secure valuable deposits over the long term Close geographical links between cement production and mining sites is also extremely important Short routes for supply of raw materials take pressure off of traffic volumes and

The milling process in cement plants is extremely energy-intensive there are potential energy savings available through the use of Mill Control System (MCS) The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledge-based approach using current plant data (defined measured values)

A disadvantage is that the fuel mill has to run all the time if it breaks down the kiln has to stop if no backup system is available In indirect firing the fuel is ground by an intermittently run mill and the fine product is stored in a silo of sufficient size to supply the kiln though fuel mill stoppage periods

Cement consumption is dependent on the time of year and prevalent weather conditions Nearly two-thirds of U S cement consumption occurs in the six months between May and October The seasonal nature of the industry can result in large swings in cement and clinker (unfinished raw material) inventories at cement plants over the course of a year

Sep 18 2013If a cement producer can supply this test report it is very useful because the samples used are grab samples not composites and many are taken each month The test results give a good idea of how much a particular cement's strengths vary on a short-term basis and thus may be more useful than the standard mill certificate

A demand management system limits energy demand through load shedding and peak shaving strategies It helps reduce demand charges and manage real-time power purchases or to minimize load during a curtailment period For example a steel mill was using 90 000 MWh of electrical energy per month at a cost of $2 7 million each year
