Versatile machines rise to quarry challenges

TEREX Finlay’s J-1480 jaw crusher and 883+ heavy duty screener are proving their worth at Skene Group’s two quarries at Soutra Mains and Lomond Quarries.

Both quarries operate two-tier bench systems and the machines, which were supplied by Finlay Scotland, are moved between the quarries and faces to satisfy production requirements.

For the past 50 years, Skene Group have been involved in the processing of quarry material, groundworks and in the production of concrete blocks and ready-mix.

The J-1480 jaw crusher was ordered and built to a high level with many optional factory fitted extras. Finlay explained that the pre-screen incorporated on the machine is doing an “incredible” job and increasing production during the winter months, even with sticky materials that have traditionally proven to be a challenge. This option is designed to prevent build up and blockages in the crusher chamber by removing fines that don’t need to enter. When blockages do occur the hydrostatic drive arrangement of the plant means that the reverse running of the chamber can be engaged to help clear blockages.

The 883+ heavy duty screener is being operated along with the J-1480 jaw crusher. This plant was also built to a high specification with chassis riser and extended fines and middle grade conveyors to maximise stockpile capacity.

Both machines are fitted with the Terex Finlay T-Link telematics system as standard. The T-Link telematics system enables Skene to remotely monitor the machines’ performance and ensure the regular preventative maintenance is scheduled as required.

Darren Forrester, Skene Group’s joint managing director said, “We are very pleased with the performance of both machines. The pre-screen on the J-1480 is doing a great job and improves the flow of material into the jaw to deliver impressive tonnages even with the sticky materials during the winter period. Both machines are versatile for us and enable us to move the machines between and around our quarries depending on the production demands. What also attracted us was the back up support we knew that we’d get from Finlay Scotland. It was a combination of machine performance and the back up support that gave us the confidence to order a second J-1480 crusher and we look forward to taking delivery of the new machine.”

Finlay Scotland sales executive Euan Fairweather added, “I’d like to thank Darren Forrester for giving us this opportunity and trusting in Finlay Scotland. Both machines have proven themselves in the difficult and abrasive environments on both Skene quarries and giving excellent tonnages. Both machines are playing a critical part in operations to ensure high value products are processed with maximum output. The material goes straight into the J-1480 and the machines’ independent pre-screens and large chamber opening make it ideal for this type of application before being screened by the 883+ screener. The machines also offer the ability for Skene Group to re-configure them to offer a number of flexible options to meet market demand.”

A fleet of Terex Finlay cone crushers and screeners are also benefiting Tillicoultry Quarries. The firm has taken delivery of two C-1550 cone crushers and 693+ and 694+ inclined screens from Finlay Scotland for their hard rock quarries, sand and gravel, asphalt, concrete readymix and recycling operations.

The machines are proving themselves across the company’s 11 sites, producing products with high tonnages to meet increased demand for the high quality processed products that Tillicoultry produce.

Wallace Menzies, managing director at Tillicoultry Quarries said, “The operators and site managers are very happy with the new machines and I’m confident that they will continue to increase our productivity and ability to supply our customers with the products they require.”

The Terex Finlay C-1550 cone crusher features the Terex TC1300 cone crusher, which is choke fed with an integrated level sensor, automatic tramp relief and hydraulic closed side setting adjustment to maximise production. To protect the cone, the feed belt is fitted with an automated metal detection and purge system.

The 693+ and 694+ are compact three and four-way split mobile screens that are suitable for working in a range of applications including fine sand and gravel fine screening, recycling and quarrying.

Adam Rhind from Tillicoultry Quarries added, “I’ve been extremely pleased with the reliability and powerhouse performance of each of the machines. The ability to redeploy them across our sites is a real benefit to us and typically the machines are operational 30 minutes after they arrive on site.”

Finlay Scotland’s Morris Wightman commented, “The machines are working exceptionally well and playing a key part in operations to ensure high value products are processed with maximum output. We’re grateful that Tillicoultry trusted in us when they made the decision to buy the new equipment, extending our close business relationship of over 10 years.”
