Aggregate Processing Solutions has provided an uprated Terex Finlay TC 15 Sand Master to boost productivity on site at Hanson Aggregates in Mercaston, Derbyshire.
The machine has been brought in as part of a 28-week contract, which will see the sand and gravel quarry produce volumes that would normally be achieved over an 18 month period.
With a processing power of up to 120 tonnes an hour of sand, the modified TC 15 offers a quick and efficient way for the quarry to meet tight deadlines and product specifications.
The TC 15 works with a chassis mounted, Terex Finlay MP300, mobile washing system, a Terex Finlay 390, two Terex Finlay 532 conveyors for sand stockpiling and a Terex Finlay 683 producing three grades of gravel.
Brought in to replace an older permanent static system, the TC 15 has two 24 inch cyclones and produces a -2mm fine sand to meet Hanson's specification.Raw material is stockpiled before being fed by the 390 to the MP300 washing system.
Sand from the on-board rinsing screen then flows to the TC 15. Plus 2mm gravel passes through the integral Terex Finlay 206 logwasher, which delivers onto a de-watering screen which has been configured to produce a 2mm — 5mm grit product.
Anything above 5mm is fed through the Terex Finlay 683 Supertrak in order to produce three grades of gravel, 10mm, 14mm and 40mm.
The TC 15 Sand Master's low level feed-in and easy to access pumps helps keep maintenance simple.
As well as rubber lined centrifugal pumps and impellers, an electric control panel is fitted as standard, which facilitates two 7.5 Kw stockpilers, enabling the sand system to be easily incorporated into an existing washing arrangement.
Andy Bull, the quarry manager at Mercaston Quarry, said; "The TC 15 Sand Master is quick and versatile, and is extremely compact and easy to locate, even with the uneven ground we have here.
"It deals with our time, space and surface limitations really well and is a durable, fast working machine.
"Importantly, it uses under half the amount of electricity and water that was consumed before, saving the quarry a lot of money."
Bob Parker, the contracts manager from Aggregate Processing Solutions, said: "The TC 15 is perfect for the fine sand at Mercaston and has enabled us to meet our contractual obligations in terms of production and product specification."
