Tracked conveyor is the ‘missing link’ for Breedon

BREEDON Northern has invested in the largest Terex Finlay tracked conveyor currently available from Finlay Scotland. The TC-100 is being used as a link conveyor in a static aggregates production plant.

Situated in Breedon’s Daviot Quarry, seven miles south of Inverness, this 100ft conveyor is providing a link between two static sections of the plant, carrying out a job that was previously completed by a loading shovel.   

This section of the production process starts with an Allis Chalmers 11-36 secondary cone crusher, from which the material flows into a Terex Finlay 883+ heavy duty screener. The mid-size fraction is then fed onto the TC-100 conveyor, with oversize material recirculated thorough the 11-36. At the end of the 30m conveyor, the material is dropped into a feed hopper and then into a static Metso G158 cone crusher before being separated into saleable products by two Terex Finlay 694+ inclined screeners. wCapable of handling 600 metric tonnes per hour, the TC-100 can either be used as a link or stockpiling conveyor. 

Figures from the testing carried out by Terex Finlay suggest that in a typical application where a crusher is producing 400mtph, it would only take around 17 minutes for the discharge height of the crusher to be reached. A loading shovel would then be required to clear the stockpile continuously from this point. However, using a TC-100 set-up at 24 degrees, with a 12.5m discharge height, it would take over 14 hours of production until the material would need to be cleared. 

Alan Scott, Daviot Quarry manager said, “The TC-100 has been with us for a few weeks now and it has really helped tidy up our process. When it first arrived, I was impressed by how substantial the build of the machine is. It hasn’t missed a beat yet and the signs are good for the future. We had previously been using a loading shovel to move the material from the first cone across to the feed hopper, but the TC-100 has allowed us to release that shovel onto other tasks and at the same time simplify our operation.”

Tom McNeil, MD of Finlay Scotland added, “Our long-standing relationship with Breedon Northern has always been based on us working to provide them with new technology that can help them boost their production and improve efficiency. As soon as Terex Finlay told us about the range of conveyors becoming available, it was simply a case of using our knowledge of their site to advise where a conveyor could improve their process.”
