The plant manufacturer as service partner

Summary: By example it is shown how the plant manufacturer can help to minimize the plant stoppage period required for component change-outs and the performance of repairs, thanks to his know-how as the supplier of machines and systems for kiln and grinding plants. The example concerns the refurbishment of a kiln plant equipped with a satellite cooler within the agreed time period, within the specified budget, to a high quality and – of great importance – without any accidents. The service package included the flat-rate installation of plant components, surveying of the rotary kiln and a mobile machining service for key components that could be reused. The refurbishment was performed on the basis of a detailed appraisal of the plant that was carried out on site before the order was awarded.
