In addition to new modern concrete plants we could find nowadays in operation also old concrete plants which age ranges over 25 years. This plants work in configurations which were originally designed and built or have already undergone partial reconstruction. Reasons for the reconstruction may be for instance enhancement of concrete plant performance, improvement the quality of concrete produced, increasing the efficiency of the production process of concrete mixture and similarly. After thorough reconstruction performed concrete plant can usually operates for many years. Lifetime lenght of the reconstructed concrete plant depends largely on the previous good service and quality maintenance.
