Stevens Group offers a full range of high-performance mobile screeners, including the fuel-efficient Chieftain 1700X
Supplied nationwide by Stevens Group, the Powerscreen Chieftain is one of the brand’s most popular screening machines, ideal for small to medium-sized operators and contractors needing a versatile solution for various applications, including sand and gravel, aggregates and recycling.
Within the range there is a model to suit virtually every application, from the legendary Chieftain 1400 to the monstrous Chieftain 2200, with all machines designed to be easily transported, set up, operated and maintained while giving excellent tonnages of in-spec material.
25 years of the Chieftain 1400
This year marks a milestone for the Powerscreen brand, it being 25 years since the iconic Chieftain 1400 was first shipped out from the factory in January 2000. Since then, over 5000 units have been delivered worldwide.
At the core of the Chieftain 1400 mobile screen is the time-proven, high energy Powerscreen 11’ x 5’ (3.33m x 1.53m) four-bearing, two-deck screen box.
In addition, a variety of subtle updates and additions to further enhance the productivity, serviceability and reliability of the Chieftain 1400 screen. Highlights include improved access, increased serviceability and an extended feed hopper to accommodate the trend towards larger wheel loaders.
Chieftain 1700X
Built on the success of the original Powerscreen Chieftain 1700 and launched in 2021, the latest upgrade of the successful incline screen, the 1700X contains numerous features that offer customers increased throughput with significantly improved fuel efficiency.
Chieftain 1700X is a mid-sized track mobile screen with two or three decks, aimed at end users requiring high volumes of finished products in applications involving topsoil, coal, crushed stone, recycling, iron ore, sand and gravel.
User benefits include a quick set-up time, drop down tail conveyor and screen mesh access system to aid screen media changes and a transverse power unit arrangement to simplify servicing.
One of the new benefits of the 1700X is the patented four-bearing screen box configuration as standard giving an extremely aggressive box with 17.5% more G force than its predecessor.
For those preferring a different setup, the new 1700X can easily be adapted to a two-bearing machine, giving versatility for a range of applications.
As well as increased throughput, the Chieftain 1700X is one of the most fuel-efficient machines available, say Powerscreen. The pumps are set to run at 1800rpm, compared to 2200rpm on the older model. The reduction in speed is said to reduce fuel usage by around 10% without any power reduction,
Features include
- Radio-controlled tipping grid
- Hopper: 5.35m3
- Powered by Stage V compliant CAT 4.4 engine
- Heavy-duty single shaft screen box / Adjustable stroke, angle, and speed
- Output Potential: Up to 500 tph
- Screenbox: 16’x5’/4800mm x 1500mm
“Several Powerscreen Chieftain 1700Xs have been placed into work in New Zealand. The throughput has noticeably increased, and it is using at least 10-15% less fuel, making it more efficient and therefore more sustainable,” says Lincoln Rayner, sales director at Stevens Group.
Production goals
Choosing the right screener depends on the material type and production goals. With many mobile screeners available, the team at Stevens Group say they can help select the best type of equipment so owners can maximise utilisation and profits.
Incline screens
Incline screens are angled screens that take advantage of gravity to help shuffle materials down the screen deck for proper separation. They grade materials by size, separating smaller particles from larger ones and are often used for fine screening applications. Powerscreen’s proven plants such as the Chieftain range feature large screening surfaces, allowing users to keep up with high-capacity demands.
“Tracked inclined screens are versatile, high capacity, robust and durable machines that can be operated in a wide range of primary and secondary screening applications,” says Catrina Quinn, marketing manager.
Chieftain screen advantages
- A tipping grid over the feed hopper prevents large material flowing onto the screen and damaging the media being used to separate the products
- Energy efficiency due to the assistance of gravity, incline screens require less power to operate
- Can be easily integrated with other plants/machinery
- Can remove unwanted materials from a mixture, which can improve the quality of the final product
- They usually have a slightly lower cost to entry than horizontal screens due to a simpler design and few moving components
- The incline screens are available with two or three screen decks verses scalping screens, which feature two screen decks
- Incline screens feature a steeper angle for fast screening after crushing
