The Terex|Finlay 674 is a compact, easily transportable machine that offers operators rapid set up and tear down times, according to the company. The screenbox features three decks, giving a large screening area to provide efficient screening even at small fractions and high capacity.
The screenbox features quick wedge tensioning, access holes and bottom deck hydraulic tensioning system to reduce time required for mesh changes. All four discharge conveyors are adjustable and hydraulically fold for transport. The fourth product “oversize plus” conveyor has variable tilt and side slew to discharge material for recirculation and stockpiling.
• Triple deck screen with galvanized all round fixed catwalk access for ease of operation and maintenance.
• The fourth (oversize plus) conveyor provides variable tilt and slew capability to discharge materials for recirculation to crushers or for stockpiling.
• Maximum utilization of the three decks provides screening capabilities even at small aggregate sizes.
• Updated hopper and belt feeder gives improved material flow onto main conveyor.
Heavy Duty Screen
According to the company, the Terex|Finlay 893 is a highly-versatile and aggressive machine engineered and built for working in large-scale quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal, ore and aggregate applications.
The plant has the capacity to process at a rate of up to 882 tons (800 t) per hour and can be fed either by a tracked mobile crusher, shovel or an excavator. Depending on the application the working angle of the screenbox can be hydraulically adjusted to between 14 and 18 degrees.
A key feature of the machine is the capability to change the working angle of the hopper/feeder. The working position can be lowered so that it can work with a mobile crusher.
The hopper/feeder working position can be raised to provide a reduced feeder angle when operated in direct mode from an excavator or shovel. The screenbox top deck can be fitted with a variety of screening media including mesh, punch plate, bofar bars and tines.
The bottom deck can be fitted with mesh, punch plate and cascade fingers. This fully self-contained plant can be hydraulically folded and ready for transport in less than 30 minutes, according to the company, making it the ideal machine for large-scale contract screening projects where a highly productive and dependable screen is paramount.
• Versatile screen box can be adapted to suit many applications.
• Modular configuration screen box with 20 ft. (6.1 m) by 6 ft. (1.83 m) top deck and 18 ft. (5.5 m) by 6 ft. bottom deck screen.
• Screen box angle can be hydraulically adjusted to an angle between 14 and 18 degrees.
• Screen box discharge end can be hydraulically raised 24 in. (61 cm) to facilitate media access and changing.
• All stockpiling conveyors are hydraulic angle adjustable with hydraulic extending head sections for maximum discharge and stockpile height.
• Apron feeder angle adjustable, lower position to accommodate crusher feed, high position provides reduced feeder incline angle when operated in direct feed mode from excavator/loader
Heavy Duty Screen
The Terex|Finlay 873 is suited to working in aggregates, sand and gravel, top soil, construction demolition and recycling applications. This machine can be fed either by a tracked mobile crusher, shovel or an excavator and has the capacity to process at a rate of up to 496 tons (450 t) per hour. This machine is now available with dual power technology option. On-board electrical motors allow flexibility to run from an outside power supply or standard onboard engine.
• Screen box angle can be hydraulically adjusted to an angle between 13 and 19 degrees.
• Screen box discharge end raises hydraulically 20 in. (50 cm) to facilitate mesh changing.
• Screen box can accept punch plate, cascade fingers, bofar bars and speedharps.
• Galvanized access catwalk on both side of screen.
• Oversize conveyor angle can be adjusted from 18 to 24 degrees.
• 4 ft. (1.2 m) wide belt feeder complete with 9 cu. yd. (7 cu m) manual folding hopper.
The Terex|Finlay C-1545P incorporates the Terex 1150 cone crusher driven through by direct clutch drive with variable speed, automatic tramp relief and hydraulic closed side setting (CSS) adjustment.
The machine features an on-board forward facing prescreen module with a 7 ft. (2.1 m) by 5 ft. (1.52 m) single deck screen for removal or bypass of fines from the feed material. The fines material can be discharged from the machine using the optional on-board by-pass conveyor or reintroduced onto the main product conveyor.
According to the company, both methods improve the overall plant capacity, product flexibility and liner wear reduction. In applications where pre-screening of the feed material is not required the module can be hydraulically repositioned beneath the hopper/feeder. This provides a more compact working envelope as the feeder/hopper can be hydraulically adjusted to feed directly into the cone chamber.
• Terex TC1150 cone crusher provides high reduction and productivity ratios and gives excellent product cubicity, according to the company.
• The forward facing pre-screen module maximizes production and reduces wear on the chamber by removing fine materials before it enters the cone.
• The large hopper/feeder on the plant has an automated metal detection system to protect the cone and reduce downtime.
• The pre-screen module can be used to produce a road-base product from the on-board side conveyor.
