Fact. Relying on reactive maintenance costs money and time.
The aggregates production process consists of plant assets such as conveyors, crushers, pumps and fans. Losing any of these assets can have a catastrophic effect on plant production and therefore regular maintenance of these assets is essential. Asset performance has two parameters to consider which are asset utilisation and asset availability. In simple terms, availability is the ratio of the actual asset run time compared to the planned run time for that asset. Utilisation is the proportion of time the asset is used, which is an indicator of how production runs are planned.
Assets need to be available to run when you need them so there is a need to utilise your assets to maximise efficiency and manage our energy costs.Traditionally, across many production facilities, preventative maintenance regimes have been deployed, which involve scheduled periodic shutdowns to carry out plant maintenance. Essentially this strategy is ok as it has a positive effect on availability as regular maintenance is carried out. However, it has a negative effect on utilisation as the whole or part of the plant is shutdown regardless of whether all the assets need maintenance or not.
