Hewitt Robins have recently supplied a bespoke, made to measure replacement screen to replace a 40+-year-old failed Niagara D-11 screen at Hanson Penderyn Quarry – South Wales.
Hanson’s existing Niagara screen that had been carefully maintained for 40 years but following the breakdown required urgent replacement. Hewitt Robins offered a completely new machine at a very competitive price designed to fit into the existing building with no modification.
As the existing machine was non-repairable delivery of a new screen was very important. The new Hewitt Robins V-11 1.6 x 4.8 Double Deck Inclined replacement screen was designed, manufactured and ready for installation in a just a 4-week timescale.
The Hewitt Robins engineers went down to the site on the same day as receiving the order and carried out a full-scale measure up of the existing screen and installation. They then worked around the clock and modelled up the screen to suit the existing support structure within 4 days of receiving the order. This allowed time to manufacture the screen within the 28day period.
The Hewitt Robins V-11 1.6m x 4.8m double deck screen is constructed of 10mm thick side plates with cross member spacing every 600mm. The 2 x 110mm bearings, oil lubricated screen was also supplied with High-Efficiency 11kw drive motor, pivoting motor base, close fitting drive guard, coiled springs, rubber side tensioned mats on the top deck and high carbon woven wire on the bottom deck.
Gareth Evans, Q.M, Hanson Penderyn commented:-
”We had a dilemma on whether to carry out a major overhaul on the existing screen or replace it with a 2nd hand machine from another one of our sites. We then found Hewitt Robins were who have replaced a number of Niagara’s D11 screens in the past. Hewitt Robins offered us a screen made to measure and to fit into the existing building with an extremely quick delivery to suit our requirements. We found Hewitt Robins to be very professional, easy to work with and their price was extremely competitive. The most important thing for us was the quick delivery and to deliver a complete machine ready to lift in within just 28 days from receiving the order was very impressive.
