Hewitt Robins have recently completed a turnkey project to replace a failed Niagara screen at Lafarge Whisby within a 4 week timescale.
The existing Niagara screen was non-repairable so delivery of a new screen in the shortest timescale was very critical. The new Hewitt Robins V-13 1.8 x 6.0 Double Deck replacement screen was designed, manufactured installed and commissioned in just 4 weeks. This short delivery allowed Whisby to stop production for 4 weeks whilst the machine was being built.
Hewitt Robins supplied a replacement screen that was specially designed to replace the Niagara Screen. The replacement screen had to be designed so that it could fit into the existing structure and picked up the same footprints will little or no modification.
The new Hewitt Robins V-13 1.8m x 6.0m inclined double deck screen is constructed of 10mm thick side plates with cross member spacing every 600mm. The 2 bearing oil lubricated vibrator unit was also supplied with an 11kw drive motor, close fitting guard, coiled springs, new spray bars and manifold, rubber cross member protection and the existing modules were re-used off the original Niagara screen.
Stuart Moore – Quarry Manager, Lafarge Whisby commented: ‘’ The Hewitt Robins Screen installation went well, on time and on budget. Operationally the screen is meeting our expectation and our production requirements. Hewitt Robin’s commitment and professionalism to the project has been much appreciated.
