Finedoor complete a successful screen installation for Fife Silica Sands.
Thursday, 5th July 2012

Bespoke Quarrying and Recycling Solutions provider, Finedoor has recently completed a project at Burrowine Moor Quarry which is owned and operated by Fife Silica Sands (FSS) who are a division of Paterson's of Greenoakhill Ltd.

With a history as a family firm spanning back to 1826 Paterson's Quarries Ltd (PQL) was founded in 1973 with one quarry in the South-East of Glasgow. Over the last 3 decades PQL has expanded to become one of the largest independent quarry operators in the UK with a turnover in excess of £51 million.

Today its business diversifies from quarrying to a wide range of complimentary activities ranging from concrete block manufacture, to waste management and engineering.

Burrowine Moor Quarry is located approximately five miles from Kincardine Bridge, providing ready access to the M8 and M9 motorways, with the deep water port at Grangemouth situated eight miles from the quarry offering a ready source for shipping.

With reserves of silica sand deposit the quarry supplies a range of products including: flint quality glass sand, foundry sands, construction products sands, mortar sands and filtration, horticultural and sports sands.

The installation

The production process requires a feed of 130 tonnes/hr of primary feed to be washed for the initial cut of sand, further on in the process a secondary screen removes any shale or lignite from the sand. 
With both screens needing replacement, Finedoor conducted a site visit and after consultation secured an order for a Sotres dewatering screen which was supplied on a supporting frame to fit onto the existing steel support structure and underpan.

This new screen covered a smaller footprint and was positioned to discharge into the existing lignite bay with modifications made to the existing feed pipe into a new feed box.

Finedoor are the UK distributor for Sotres Washing and Water Treatment equipment. With over 1000 installations in Europe, Sotres has more than 25 years of experience in washing and preparing concrete sands in quarries and pits and is an ideal partner for Finedoor who provide turn-key solutions in the Quarrying and Recycling industries across the whole of the UK and Ireland.

The second screen supplied was a Finedoor 4.2 x 1.5 - twin-deck aggregate rinsing screen, designed to fit in the existing location. Jim Blanchard - Director at Finedoor, commented, "We specialise in dimensionally similar replacement screens, this means a new unit can be installed into an existing location, designed and manufactured to sit on the existing steelwork. The existing feed / discharge chutes and conveyors usually require very little, or no modifications to existing plant, thereby reducing costs and installation time."

With the supply of the rinsing screen Finedoor recommended the fitting of deck frame and drive tube wear protection. From past experience this has been found to maximise the life of the structural members in the harsh environment of screening.

The wear protection is replaceable but to date on machines supplied, replacements have not been required. Finedoor also recommended installing a polyurethane screen media plank system to ensure the screen cross channels are fully protected. This facilitates easy fitting on the bottom deck as the securing method is by wedges in-line with the material flow.

The whole installation was completed and commissioned by Finedoor engineers within the allotted time frame, although Finedoor had to completely rebuild the structure under the dewatering screen, which also included the manufacture of a new spray bar manifold.

John McCann - Quarry Manager, commented " From start to finish Finedoor conducted all operations in a totally professional manner, the downtime incurred was kept to an absolute minimum, we were kept fully abreast during the manufacturing of the screens, in fact Finedoor actually managed to pull forward the installation date, due to an unforeseen onsite problem"
