Cement kiln safety and performance improvement based on

Occupational health and safety has top priority within the cement industry. The preheating tower with its series of installed cyclones is essential in the cement kiln production process and it is considered among the most dangerous places in a cement plant. Coatings and blockages can often occur in the cyclone preheaters of rotary kiln Process knowledge is not like a preheater, a kiln or a mill. You cannot point to it or touch it. But it is as integral to the performance of your plant as those large pieces of equipment. We might even say it’s more important because it underpins everything else from the design of the machines to the layout of the plant, the optimization of the process, the management Process Knowledge KHD Humboldt Wedag
