After 27 years of continuous operation and having been involved in the processing of over 50 million tonnes of material, two fine screens at Dove Holes Quarry have successfully been replaced during a 10 day Easter shutdown.

The new designed units have been marginally updated, yet otherwise identical, and were manufactured locally by Don Valley Engineering. This continuity in design reflects the robustness of the original equipment, while subtle improvements help future proof the Plant and improve material quality. Throughout manufacture, the Dove Holes quarry team quality controlled every stage of the process, with the aim of delivering another 27 years of reliable, uninterrupted service.

The photos capture the scale of the work, showing one of the new screens being installed in the wash plant building, while, at the same time, the primary crusher rotor was being changed during the same shutdown. Completing two major pieces of work in parallel demanded detailed planning, close coordination, and disciplined risk management to ensure zero accidents and return to operation slightly ahead of schedule.
