TEREX Finlay, part of Terex Corporation, has launched the new Terex Finlay 684, a two-deck tracked mobile inclined screen that has been engineered and built for working in quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal and aggregate applications.

“This product is the latest in our stable of 6-Series tracked mobile inclined screens. The product has been robustly tested in numerous applications throughout the UK, Ireland, Continental Europe and also the Southern Hemisphere,” says Brian Pauley, marketing manager. “We have been extremely impressed with the results that were experienced throughout the two-year testing period and also the intake of initial machine orders.”

The highly versatile and adaptable screen is a compact easily transportable machine that offers operators rapid set-up and tear-down times, according to Pauley. The new screenbox on the Finlay 684 features two full-size 4.3 m by 1.7 m inclined decks, with full catwalk access, providing efficient screening and high capacity.

Maximum utilisation of the two decks provides ultra-efficient screening capabilities even at small aggregate sizes, Pauley says.

“A combination of quick wedge tensioning on the top deck of the screenbox, convenient access holes and hydraulic tensioning on the bottom deck ensure mesh set-up and change out times are kept to an absolute minimum,” he adds. “All three discharge conveyors hydraulically fold for transport, providing the operator with rapid set-up and tear-down times.”

A high-performance 1,050 mm (42 inches) variable speed belt feeder, with a hydraulic gearbox drive, is fitted to the machine as standard and has proven performance and versatility in demanding and varied working environments, Pauley points out. The hopper has an 8-cu-m capacity as standard and can be fitted with a 14-ft tipping grid or 12-ft vibrating grid.

This fully self-contained plant can be hydraulically folded and ready for transport in less than 30 minutes, making it the ideal machine for contract screening.

Terex Finlay has been manufacturing a range of mobile crushing, screening and recycling equipment for more than 50 years. The company as a unit of Terex Mobile Processing Equipment (MPE) forms part of Terex Corporation’s material processing business segment which also includes Powerscreen, Terex Minerals Processing Systems (MPS), Terex Environmental Equipment and Terex Washing Systems (TWS).

TWS

Meanwhile, TWS is launching what it expects to be a new global market leader in innovative washing systems. The AggreSand system, the latest addition to an already extensive product portfolio, combines aggregate washing and screening with sand processing on a modular chassis. It brings together tried-and-trusted TWS components in an innovative modular design, setting itself apart from other washing systems in the marketplace.

“A gap in the market for such a washing evolution was identified following extensive research, part of which was conducted at the Terex Washing Systems first-ever product development forums. This involved TWS engineers and sales technicians working with the global distributor network to formulate the concept,” says a company official.

Central to the development of the new plant was a modular design, pre-wired and pre-plumbed making it quick and easy to set up and easy to maintain. The plant also includes a range of other innovative features and designs.

Sean Loughran, director of TWS, comments: “The AggreSand system will represent the epitome of washing in the marketplace and is a combination of significant enhancements and design changes to existing products as well as the introduction of new pioneering ideas. In our ongoing efforts to meet and exceed customer expectations, the AggreSand system will enable TWS customers to wash a wide range of materials at a high specification and produce up to five products.”

The key features and benefits of the AggreSand System include:

• H 12 hopper: This new modular hopper feeder with 12 cu m capacity is in keeping with ever increasing loading shovel sizes in today’s modern quarries and sand pits. It is available with an automatic tipping grid and a 12-foot, two-deck vibrating grid complete with variable speed belt feeder, all controlled from the main operator interface and radio control unit.

• Feed conveyor: The wide feed conveyor has a direct drive electric motor and gearbox arrangement and will work at a 19-degree angle when feeding the AggreSand system. The inclined feed conveyor features an innovative sealed wash box at the discharge point to give material a pre-rinse to pre-condition for screening. The design eliminates splashing and produces an even distribution of material.

• 165R-3 rinsing screen: The riveted construction of the 165R-3 (three deck, two bearing) rinsing screen helps isolate the spray bars from all vibration, utilising high quality rubber gators on the mid and bottom decks. Top deck rubber extensions also prevent overspill or splashing from the top deck screen. The 165R-3 gives a true 80-sq-ft of screening area on all three decks.

• 125 dewatering screen: The high-energy dewatering screen is fitted with two high-efficiency counter rotating vibratory motors which remove capillary water to produce two dewatered sands.

• Integrated conveyors: The system has the option of five conveyors – three for aggregate and two for sand. The 9.3-m-long, 650-mm-wide conveyors are powered by direct drive electric motors and gearbox arrangements and angled at optimum height for excellent production.

Other features of the AggreSand system include a large-capacity sump tank, two centrifugal slurry pumps to pump material into two hydrocyclones, accessible service areas, a cutting edge user-friendly control system and tried-and-trusted Terex components in an innovative modular set-up.
