Continuous process sampling and X-Ray analysis of the process intermediates and clinker ensures that the burning process is continuously optimised to produce the highest quality clinker.
For each tonne of material that goes into the feed end of the kiln, approximately two thirds of a tonne exits the kiln as nodular clinker. The clinker is then very finely ground in a large rotating ball mill to produce different types of Portland Cement. A small amount of gypsum is also added during the grinding process to control the cement's setting characteristics.
While the basic principles of the Cement Manufacturing process have fundamentally changed very little in the past hundreds of years, the technologies employed in order to achieve maximum clinker production per energy expended, coupled with the lowest emissions possible, have continually developed to their current high levels of efficiency.
As a new and modern manufacturing facility, utilising all the state-of-the-art technologies, Lagan Cement are well prepared to meet the environmental and production challenges of the coming years.
Lagan Cement uses a combination of traditional and alternative fuels to fire its kiln at the Killaskillen plant. Apart from additional Fuel-handling systems, the use of alternative fuels does not involve any changes to the actual cement making process.
