Finedoor supply the first mainland UK Sotres Sand Treatment Unit to Potgate Quarry.

Monday, May 10th, 2010

Lightwater Quarries Ltd, a company wholly owned by the Staveley family operates two quarries, one of which is Potgate Quarry near Ripon. Well established, the quarry supplies a hard magnesian limestone for road construction and other applications throughout Yorkshire.
With a busy operation of this nature it is of prime importance that the processing plant operates efficiently; however it had become apparent that the existing screw/bucket dewatering unit was losing fine sand to the settling lagoons. It was therefore decided after consultation with Finedoor that it would be beneficial to replace the inefficient unit with a modern hydro cyclone sand treatment unit.
With a requirement that the new unit must recover 100% passing 150 micron Finedoor guaranteed the performance and offered a suitable unit which was available for immediate delivery from their sand processing and water treatment partner Sotres SA in France.
Installed during the Christmas/ New Year holiday period initial grading taken after a few days after commissioning reflected excellent results, with tests on the waste water indicating nothing passing 75 micron was entering the lagoons.
Capable of producing up to 80tph the Sotres unit supplied is a compact sand plant featuring a galvanised dewatering screen unit which is supplying a single grade of sand. Finedoor also supplied a Warman pump specifically supplied ‘one size up’ to minimise wear.
Finedoor engineers commissioned the sand plant and all the civils were provided by Lightwater engineers.
Kevin Parker – General Manager, commented, “It was clear to me that Sotres have plenty of experience in sand plant design and their confidence in their product made the purchasing decision easy. Finedoor gave good support and ensured the plant would slot into place in the short shutdown period and despite the bitter weather everything went to plan.”
Sotres SA is a partner of Finedoor and this is the first sand treatment unit to be installed in mainland UK. Numerous units have been installed in Europe and worldwide, with a growing population in Ireland in recent years. Robust and built to last Sotres has full laboratory facilities and are available to design and manufacture equipment for sand processing, water and filter pressing specific to customer requirements.
All Sotres sand and processing water treatment plants are available in the UK from Finedoor of Morley, near Leeds who supply a full after sales service.
