A cement plant consists of many different machines and most of them are not
interested for the refractory point of view. However, the kiln, the preheating
system and the cooler operate in a very high temperature range and therefore
are lined with refractories. The lining protects the steel construction against
heat, abrasion and chemical attack, and is a key parameter in the design and
maintenance of the equipment. Na'aman high quality materials at the proper
areas, could enlarge the lining life time, shorten maintenance shut down time
and save operations costs.
