It's well known that following the extraction and crushing operations of aggregates, the screen house is the ‘engine room’ of a quarry where it processes and grades the aggregates. Its principle function is to sort the sizes of aggregates and ensure the right product is there, ready for coating, stockpiling or direct loading out onto transport. The main process challenges encountered in the screen house are the high dust levels, noise and vibration from the screens themselves and the associated machinery, as well as it being a very inhospitable environment for personnel.
