As the cost of refractories is a major expense in operating a cement plant, kiln stoppages are avoided as far as possible. As the meal passes through the burning zone, it reaches clinkering temperatures of about 1400 C - 1500 C. Nodules form as the burning zone is approached.

The cement manufacturing industry is identified by North American Industry Classification System (NAICS) code 32731 (formerly identified as SIC code 3241). The cement industry "comprises establishments primarily engaged in manufacturing portland, natural, masonry, pozzalanic, and other hydraulic cements.
