AllScan N-Gen the Smartest Neutron Generation Elemental Analyser in the World

• Higher performance on-line, real-time results

Accurate minute-by-minute results for multiple flow rates. Advanced n-Gen design and Dura-G technology significantly improve the performance of complete elemental analysis (Fe, Al, Si, K, S, Ti, Ca, etc.) and moisture, offering superior performance over a much more comprehensive range of bed depths than similar analysers.

• Safety

Through improved design, AllScan n-Gen can employ smaller sources, thus reducing dose rates and permitting operators to safely stand next to or near the analyser and work safely near the entrance or exit of the conveyor with minimal exposure.

The source is contained in a fireproof and drop-tested housing and has an automatic fail-safe as standard. The source can also be switched off from the walkway (even while the conveyor is running) to reduce exposure so that maintenance can be undertaken in and around the analyser.

• Rugged and reliable

Like all RTI elemental analysers and gauges, the AllScan n-Gen has been designed to work in harsh mine environments—100% constructed from corrosion-free materials, i.e. stainless steel.

• Easy to install

AllScan n-Gen is considerably lighter than conventional elemental analysers and bolts onto most conveyor structures without alterations or foundations required—only five days for complete installation, commissioning and calibration.

• Low running costs

All military spec. Components used in the analyser eliminate the need for an air-conditioner and associated ongoing maintenance in hot environments.

• Easy operation

User-friendly colour touch screen with intuitive menus housed in an IP66 stainless steel control enclosure for field or remote mounting. Flexible I/O and multiple interface protocols are available to suit the client’s needs.

• Remote access and back-up

Includes a 3G/4G interface linked to a secure website for full remote diagnostics as standard—cloud-based back-up for safe archiving of essential data. Customised monthly operational, integrity and data reports are provided through remote access for support agreements.

• No belt weigher required

With the advanced analysis techniques the analyser employs, the AllScan n-Gen does not require a belt scale input.

• Simple calibration verification

No more labour-intensive material sampling. The analyser accuracy is verified through calibration standards, enabling rapid checks and returning to production quickly. Dynamic sampling will align the analyser with laboratory results.

At the heart of the AllScan is Neutron Generation (n-Gen) technology. Material on the conveyor is bombarded with neutrons emitted from radioactive isotopes or a neutron accelerator. RTI has incorporated a revolutionary new long-life neutron generator design into the AllScan n-Gen elemental analyser.

AllScan n-Gen incorporates a sophisticated algorithm – DuraG™ – that separates the effect of belt loading and profile variation on the measured spectra from the impact of elemental variation on the elemental spectra. DuraG™ dramatically reduces measurement error.

AllScan n-Gen also includes – DuraSum – a robust algorithm that eliminates the need for time-based data averaging to obtain stable results. This means that significant changes in elemental composition are reported almost instantaneously rather than minutes later. This, in turn, allows for rapid operational control. These breakthrough technologies combine with the reliability of the n-Gen measurement technique to deliver the most accurate and responsive coal elemental analyser on the market today.
The new cutting-edge design eliminates the need for Air-conditioners to cool the electronics. The AllScan package is provided in a small footprint, is fully contained and is the smallest n-Gen on the market. The AllScan n-Gen has an intrinsically safe auto-source on/off source mechanism.

The generator’s life span is more than ten years. There is a constant output of neutrons, with no decay over time, as with Cf-252 sources.

• INSTALLATION

The AllScan n-Gen is designed to be mounted on the support rails of a conveyor system and consists of four main sections:

• Two side assemblies.
• The top with source assembly.
• The detector box that mounts between the conveyor and return belts.

Individually, each section can be lifted into place by a crane. The small size and weight of AllScan n-Gen dramatically simplify installation as it can fit onto most conveyor structures without any alteration. In addition, there is minimal intrusion onto walkways.

• MAINTENANCE

The only maintenance requirement is that regassing is required every 2.5 – 3 years. When neutrons collide with an element in the material, gamma rays are emitted with a specific energy unique to that element, creating a chemical signature for that element. The greater the amount of an element in the material, the greater the number of gamma rays emitted with the corresponding specific energy. An accurate analysis of the material’s chemistry is generated on a second-by-second basis by measuring the particular energy of the emitted gamma rays and the counts of gamma rays.
