Hewitt Robins supplies two replacement Asphalt Screens to Tarmac Banbury

Tarmac Banbury supplies high-quality asphalt, and as the UK's leading asphalt supplier, they offer a range of asphalt solutions to suit customers’ needs.

The existing Via Nova screens were at the end of their working life and were experiencing regular bearing failures which were causing downtime for the site. Hewitt Robins supplied two screens inline which were 1.25m x 3.20m Double Deck Asphalt Screens. These were made to measure so that minimal modifications were required to the existing plant. As the site was handling RAP material up to 300C this was one of the reasons why there were regular bearing problems. Hewitt Robins solution was to design the machines with the vibrating motors mounted outside of the dust encapsulation box and more importantly away from the high temperatures to avoid any premature bearing failures. The other advantage of this was to allow for more access between the decks which would make screen deck changes easier and safer.

The Hewitt Robins screens each came complete with 2 x Oli MVE9000 vibrator motors fitted to a machined motor beam, support springs spring base plates and side tensioned woven wire decks.

The installation of the screens was completed by Austin Engineering Services who also replaced the dust hood. The site is really happy with how the job went, and the unit Manager Tim Homewood commented:-

‘’We were really happy with what Hewitt Robins were offering us and the improvements it would make to the site during our initial talks. The customised design allowed us to fit superior screens into the existing installation with minimal modifications. Given the historic problems with bearing failures on the previous screen with the unit between the decks the new screens with the motors outside of the dust encapsulation, away from the high temperatures allows us to work on the screens a lot easier and in a safer manner. It is still early days however we are really happy with the screen's performance. We would have no hesitation in recommending Hewitt Robins for any future projects’’
