The J-1175 jaw crusher comes with an independent pre-screen, while the cone crusher has pre-screen and a side conveyor.
The J-1175 has an independent pre-screen, with a very aggressive action, which eradicates as many fines as possible, prior to the rock entering the jaw chamber.
Following the J-1175 is the C-1540 RS. The crushed product passes directly over an on-board 1.83m x 1.22m single deck screen, prior to the cone chamber. Finlay Group fitted a side conveyor under the screen, giving the option of a screened product from the J-1175.
After the material has passed through the cone chamber, it is then conveyed over a 3.66m x 1.52m single deck screen, oversize transfer conveyor, recirculating conveyor and fines conveyor.
Finlay Plant SW managing director Gareth Johnson said: “The cone crusher is also constantly choke fed, which helps develop a precise shape for the product and eradicates any shale. With the J-1175 and the C-1540 RS being perfectly matched, we have tried to cater as closely as possible to the customer’s needs.”
