Balancing volatile behaviour28 May 2012, Published under Cement NewsFollowing on from last month’s Technical Forum about the impacts of alternative fuels and raw materials, Dr Michael Clark examines the effect on kiln emissions, using the mass balance of the cement kiln as a starting point. Metallic mercury and mercury compounds are too volatile to pass down the preheater into the rotary section of a kiln What goes into the cement kiln must either come out in the clinker product or the emissions from the kiln, or it must be retained and built... |
Using alternative raw materials18 April 2012, Published under Cement NewsThe changes made to the production process of a cement plant by utilising different alternative raw materials can not only alter the dynamics of how a plant operates but can also affect the cost of production and cause blending and handling problems, says Arthur Harrisson. The addition of supplementary raw material alternatives such as foundry sand can also add difficulties when seeking to achieve a sufficiently fine raw mix. Switching from limestone to alternative raw materials can a... |
