The client needed a solution to crush and screen existing stockpiles of already crushed Basalt. Old stockpiles contained oversize and high fines content which required re-screening and crushing to make sellable agreegates. Products also need to be very clean and free of dust contaminents.
They only had a Terex Finlay 693+ (20×5) Supertrak onsite which was not able to screen out all the required sizes. They also needed the ability to crush the -40mm feed down to make smaller sized aggregates.
OPS supplied two brand new Terex Finlay units to work with the 693+ to produce the required aggregates. A Terex Finlay C-1545P Cone Crusher and Terex Finlay 984 (20×6) Horizontal Screener were put into circuit with the Finlay 693+. All material is now fed into the C-1545 cone which reduces the material down to around -20mm which is then fed into the 693+. The Finlay 693+ is setup with a 20mm top deck and 16mm bottom deck. Two product sizes are stockpiled by the 693+ and all -16mm material is sent to the 984. The 984 is setup with a 14mm top deck, 10mm middle deck and 7mm bottom deck. Four products are stockpiled from this unit.
The ability to generate 5 very sellable products from the circuit opens up new avenues for the customer. The 984, in position as the final screen, is able to ensure smaller aggregates are in spec and are dust free. All three Terex Finlay units features Australian spec options (hot climate packs) and offer excellent fuel efficiency. The 984 and C-1545 are also fitted with Finlay’s’ T-Link system which allows for offsite real-time monitoring
