Terex Finlay Celebrates 50 Years of Screening Excellence

Northern Ireland based company Terex Finlay is celebrating its 50^th year of Screening Excellence this year. Terex Finlay are well–established within the crushing industry and have demonstrated that their commitment to product development is deeply embedded in both crushing and screening industries. The company is part of the $9 billion Terex Corporation, employs 500 people at their 400,000 sq ft factory in Omagh and exports to over 80 countries worldwide and distributes and services its products globally through an established dealer network.

Mobile equipment is much friendlier to the environment plus much more flexible to the producer which allows the processing machinery to be brought to the material and not vice-versa. This flexibility saves both time and money.

In recent years, environmental pressures and financial considerations have seen an increase in the recycling of construction materials. Recycling is becoming more and more important because of the shrinking of natural aggregate deposits and the limited space available to dispose of construction waste. Terex Finlay have responded to this crisis and are now at the forefront of the recycling business. Newly developed machines such as the Trommel and Hydragrid are increasingly being used because of their flexibility and ability to produce saleable products from what was once considered waste.

Unique Position for Terex Finlay

Maximized production and reduced operating costs are some of the reasons why an increasing number of operators and contractors are choosing mobile crushing and screening equipment, one company is well placed to meet this demand. That company is Terex Finlay, the world leader in the manufacture and distribution of crushing, screening, washing and recycling equipment.

The Northern Ireland based company, originally founded by John Finlay is celebrating 50 years of success and it is easy to see why.

Primarily, a screening and washing manufacturer, the company entered the crushing market in 2005 with the production of the J-1175 Jaw Crusher.

The J-1175 is fitted with a 1070mm x 760mm (42" x 30") crusher chamber and a heavy-duty undercarriage. This crusher is highly regarded for its strength, durability and its exceptional on-site mobility.

A heavy duty vibrating grizzly feeder with automatic control to regulate the feed into the crusher, Hydrostatic drive and reverse action to assist in clearing blockages, are all major features of this unit. Its compact size, ease of transport, and quick set-up times makes the Terex Finlay J-1175 unit ideal for contract crushing and demolition/recycling applications.

Since then the company has gone from strength to strength and the most recent additions to its crushing range are the J-1160 and the C-1540RS.

The J-1160 is an outstanding unit and offers maximised productivity with an advanced control/monitoring system that facilitates automatic start/stop sequences.

Featuring a high performance 1000mm x 600mm (40" x 24") jaw chamber, the J-1160 is suited to recycling/demolition as well as quarry applications. The unit is powered by a CAT C9 (224kW/300HP) with hydrostatic transmission and with a useful reverse function to assist in clearing the chamber, should a blockage occur. The hydrostatic system also provides precise control of the chamber speed. Chamber CSS (Closed Side Setting) adjustment is fully hydraulic, and can be changed in a matter of minutes.

Startup time for the J-1160 is minimal, with the machine ready for crushing in less than 5 minutes. The heavy duty crawler tracks, and optional radio remote control unit, make on site mobility very easy.

The C-1540RS features a cone crusher and screener on one compact chassis. The machine is equipped with a Terex 40" (1000mm) cone chamber and a 12’ x 5’ 2 deck sizing screen with recirculation facility. If required the sizing screen and fines conveyor can be removed quickly for convenience/mobility.

Nigel Irvine–Sales and Marketing Director for Terex Finlay explains that: “The development of the J-1160 and the C-1540RS now gives us the ability to provide a full line of crushing equipment.

There are many success stories of the above crushers in the Indian Market both in aggregate and mining sectors. Terex Finlay J 1175 and C 1540 Cone Crushers are working in one of the highly abrasive and hard rock material near a quarry at Hyderabad.

The metal detector on the hopper with self-clearing facility is also another notable feature.

The I-1312 Impact Crusher has a hydrostatic drive, advanced electronic control system and hydraulically assisted apron setting. The Impactor is renowned for its high throughput and large reduction ratio, rapid set-up time, durability and on site mobility.

The I-1310 is aimed at the quarry and recycling sectors. Fitted with a 1000mm x 1000mm (40" x 40") Impactor chamber, the I-1310 is mounted on a heavy-duty undercarriage for ultimate strength and on-site mobility. Incorporating a hydrostatic drive system, this provides continuous monitoring and accurate control of the rotor speed. Positioned below the crusher chamber is the under crusher vibratory feeder which discharges onto the 900mm product conveyor belt. This feature makes this model ideal for recycling applications.

The I-1310RS Impact Crusher combines a crushing unit, screening and stockpiling unit on one chassis. This comprises a heavy-duty vibrating grizzly feeder with integrated pre-screen and under-crusher vibratory feeder to prevent belt damage and incorporates a 12’ x 5’ (3660mm x 1520mm) screen which feeds oversize material back to the hopper via the recirculating conveyor. Another key feature is the advanced electronic control system which ensures user operation is as simple as possible.

With plans underway to develop two new crushers, the J-1185 and the C-1560 Terex Finlay are in the unique position of being the only major manufacturer in the world to offer a complete and complementary range of Crushing, Screening, Recycling and Aggregate washing equipment.”

The Terex Finlay screening range comprises a range of 3-way and 4-way split screening units which combines the functions of scalping, screening and stockpiling into one integrated unit.

Models include the 663, 683, 693, 694 and 883. These units can work independently or after Terex Finlay crushers.

Screening equipment has always been at the core of Terex Finlay’s success and the company continues to invest in the screening range. The most recent introduction is the 984 Horizontal Screener, this unit features a 20’ x 6’ 3 deck horizontal screen. Benefits include high output, ease of maintenance and on-site mobility.

Wash Plant Range

This section has experienced unparalled success in the last few years. Operators are now getting pushed into dirtier and dirtier sand and gravel areas so dry screening will not suffice to meet specification. The same is the case with Iron Ore reserves where high percentage of alumina and silica are giving hard times to the Steel Plant owners. Terex Finlay offers a complete range of mobile and semi-mobile washing systems for Aggregate, Sand and Iron Ore. The range includes the unique Hydrasanders, Mobile Rinsers, and Logwashers. In addition recent years have seen the development of silt recovery systems as pressure grows on aggregate washing plants to deal with silt which was previously dumped in expensive lagoon systems.

Washing is the separation of silts and clays from sand and aggregate or silica / alumina from Iron Ore. Washed sand and aggregate are normally used in concrete. Clay & high levels of silt in finished concrete causes weakness/faults. Similarly high levels of alumina and silica in Iron Ore cause poor performance of the Blast Furnace / Sinter Plants.

A few of the products from the Washing Range Include:

1. Mobile Wet Screens / Rinsers
2. Hydrasanders
3. Logwashers
4. Siltmaster

Siltmaster SM 45

The Finlay Siltmaster system has been designed using the latest advancements in flocculent technology to remove silt from waste water which is produced as a result of Sand / Iron Ore Washing. Major benefits of Siltmaster SM 45 are:

• No Settling ponds required
• Less Freshwater consumption
• Eliminates risk of environmental damage due to silt contamination
• Eliminates use for draglines
• Gives a more compact, manageable plant
• Produces a manageable silt product
• Lower investment and running costs than comparable systems
