The 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...
