Current modernization and maintenance ­concepts in the cement industry

Summary: There is an increasing trend towards using benchmarking methods for deciding modernization and maintenance

Although ready-made concepts exist for all these projects, individual projects are generally approached in a customer-specific manner. The situation with respect to maintenance and servicing of cement plant is similar. Here, too, the possibilities are numerous and therefore very company-specific. This article deals with current topics on this sector.

Steps have since been taken to substantially reduce overcapacity by means of permanent or temporary factory closures. These have particularly affected uneconomical factories with wet-process kilns or poor capacity utilization in North America, Western and Eastern Europe and also in parts of Asia and South America. Furthermore, production capacities have been adapted at...
