Blending Process Control System.
To provide and install a comprehensive electrical control and power solution for a new blending process plant.
Longcliffe Quarries is one of the UK’s leading independent suppliers of pure limestone powder, granules and aggregates. The company approached Woodward Group with a brief to design the control system for a static-stone grading and processing system at the quarry, to include its installation and commissioning.
The grading system had to include a main intake crusher that takes the raw stone feed for processing. The resulting output products were then to be transported across a network of conveyors, graded and sorted by size, and delivered to the relevant storage hopper on-site.
SOLUTION & OUTCOMES:
Woodward Group’s design team worked closely with the Quarry’s production engineer to create a one-off, bespoke process specification. This included:
- Conveyor sequencing
- Integrated controls with the existing Supervisory Control and Data Acquisition (SCADA)
- Conveyor control systems
Flexing our design capabilities on a project that was not a tried and proven system, we developed a number of variations of both the design and the process, before we produced and installed a highly efficient turnkey solution.
Control System and Safety Interlocks were commissioned, with all documentation signed-off by the client.
We produced an accompanying Operational and Maintenance Manual, and provided training for the designated operator team.
