Replacement Screen supplied to Colchester Sand & Gravel Site

25 Jan 2019

Hewitt Robins has recently supplied a 'like for like' replacement screen to a Sand & Gravel site in Colchester.

This V-16 2.1 x 6.0 2.5 Deck Inclined Screen complete with a 1 shafted Vibrator Unit mounted above the screen was designed to replaced an old, tired competitors machine without the requirement for structural modifications. This screen is handling around 450tph of -100mm sand and gravel and is separating at 70mm top deck (relieving to send the oversize back to the crushers), 20mm idle deck and 6mm bottom deck.

Hewitt Robins designed this machine with rubber lined feed box, discharge lips and crossmembers to protect the screen from the aggressive application. The screen was mounted on support springs and used the same size motor as the existing screen (22kw drive motor) therefore, no electrical modification was required. Hewitt Robins also managed to increase the distance between the decks and fitted a rubber curtain in the back plate to allow for easy deck replacement and make the screen more maintenance friendly. The screen was then kitted out with Tema Isenmann WS85 system and finished off with Spray Bars and P.U Nozzles.

The installation was carried out over a 3 day period and everything was started up on time allowing the plant to get back into production.
