AMS Instrumentation & Calibration has released a series of hard seat and soft tip mini valves that are said to offer strength and durability.

The valves are available in electroless nickel plated steel, electropolished stainless steel and natural brass.

All of the vavles come equipped with both a Viton O-Ring seal and a Teflon back-up ring below the stem threads to protect them from corrosion and galling.

The stem threads are rolled for strength and ease of operation.

They also feature a patent pending body-to-bonnet, metal-to-metal seal below the bonnet threads isolating them from the process media.

The patent pending designed incorporates a unique dovetail feature that supplements the body-to-bonnet metal-to-metal which extends the pressure range of the valve without restricting the flow.

At a maximum hard seat pressure rating of 10,000 psi for the stainless steel and steel models and a 6,000 psi rating for the brass models, the Hard Seat Mini Valves have much to offer for such a small valve.

They feature a stem tip that is hard chrome-plated on stainless steel models to prevent galling, and stainless steel stems on steel models are standard, according to the company.

The valves are 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability, and conform to the MSS SP-99-1999 (R 2005) Instrument Valve Standards.

Safety Optics has released the EYRES G-Force goggle series that can be worn over prescription spectacles if required.

According to the company, the frame features non-allergenic washable NBR face foam to maximise facial comfort for extended wear and the anti-fog lens is interchangeable for versatility.

The classic pair of glasses comes with an IR5 welding lens and optional extras include anti-fog grey and clear lens inserts.

The mini style glasses, which were designed for medium to small size heads, come with anti fog lenses, non-allergenic washable face foam, and splash proofing abilities.

Endress+Hauser has released a Gamma modulator that is immune to ambient radiation.

According to the company, radiometric measurement is an extremely reliable and safe, non invasive solution for; level limit detection, continuous level, density and interface layer measurement.

Due to its non-contact detection principles, it is ideally suited for applications with extreme process conditions involving abrasive or toxic mediums, high temperatures or pressures.

In order to optimise operator safety, modern radiometric measurement systems utilise highly sensitive detectors and sources with the lowest possible radioactive strength to perform reliably.

All radiometric measurement systems become unreliable when subjected to fluctuating ambient radiation. This occurs in installations that employ gammagraphy (non-destructive material testing), have a dense population of radiometric measurement points or process radioactive slurries such as uranium.

According to the manufacturer, the gamma modulator is fitted between a system’s radiation source and detector.

It contains a slotted shaft that rotates and alternatively screens off the gamma beam or allows it to pass. Using a frequency filter, the system’s detector is able to separate the useful signal from the interference radiation.

Particle and Surface Sciences has released the Gemini VII 2390 Series surface area analysers, designed to rapidly and reliably produce accurate and repeatable surface area and porosity results.

The Gemini VII series uses the twin-tube design of the previous series of Gemini products, which is designed to ensure fast and accurate dosing of the adsorptive gas without pressure overshoot and also negates free-space errors introduced by thermal gradient variations or by initial mis-measurement of free space.

The Gemini VII 2390 is available in three model options:

The 2390a provides standard methods for single-point and multipoint BET and Langmuir surface areas, total pore volume and micropore analysis by the t-method.

The 2390p provides additional precision with the addition of a saturation pressure tube allowing the user to monitor the saturation pressure of the adsorptive on a continuous basis.

The 2390t has ability to perform a BJH or Dollimore-Heal pore size distribution using both adsorption and desorption isotherms of up to 1000 points.

All Gemini VII models permit low to high surface area measurements without requiring exotic gases such as argon or krypton.

Sandvik has released a new fully mobile crushing station for on-face mining applications.

According to the company, the machine can be equipped with a sizer, double-roll crusher or hybrid-crusher, for any client’s multiple applications.

During the design phase of the machine, special attention was paid to a compact design.

Focusing on the flexibility of the PF300 and its related system, a low design weight has been achieved, when compared to existing models in the market.

The machine’s crusher can be loaded via hydraulic or rope shovels without any temporary support, keeping the system fully mobile and rock solid under all conditions while machine excitement is significantly reduced.

The PF300 can either work in combination with a belt wagon, mobile transfer conveyors, or load bridges as the connecting downstream link to the face conveyor.

Broons have released their eCombi roller, a compaction tool designed for the patrol grading and resheeting of unsealed roads.

According to the company, the eCombi compacts freshly graded surfaces with its centrally mounted steel roll drum or single row of smooth tread compactor tyres on the rear that can be hydraulically raised or lowered to suit the application of the machine.

An optional vibrating roll drum can be fitted in lieu of the standard static weight version.

A sign rack, cutting edge holder and spare wheel have been integrated into the design if required by the client.

A steel fabricated reinforced heavy duty frame surrounds a centrally mounted steel roll drum assembly. Designed to operate in the harshest conditions, components are sealed for life and/or protected against the entry of dust and dirt, and engineered for minimal maintenance and ease of access.

The roller has a compaction width of 2m on the roll drum and slightly wider on the tyres.

The roll drum is 25mm thick and can be ballasted with water to increase its weight and compaction pressure.

Fully ballasted the operating weight of the eCombi is around 8.0 tonnes.

The static linear load of the smooth drum is close to 35kg/cm or 900kg/tyre when ballasted.

Narva has released the Megaburst high output L.E.D. strobe, designed to offer high levels of safety and reliability in harsh environments.

The lamp has a large aluminium heat sink base and cap designed to cater for the heat generated by the high output L.E.D’s.

Electronics built into the circuit board can be programmed for a variety of applications to suit the working environment.

The circuit board is protected by epoxy resin and with no moving parts and, according to the company, ultra long life of up to 100,000 hours life can be expected from the L.E.D’s.

The L.E.D’s used in the Megaburst draw less power than conventional lighting sources (1.8A at 12V) while producing less heat.

With resistance to shock and vibration the Megaburst is suited to heavy duty applications in mining operations, contractors plant and equipment, earthmoving machinery.

The lamp is designed to be virtually maintenance free and carries a 5 year Narva warranty.

The Minister for Resources and Energy, Martin Ferguson AM MP, has announced details of the world’s first commercial release of offshore areas designated specifically for the assessment of their greenhouse gas storage potential.

“Advancing storage technology and capacity is vital to the future of Australia’s coal industry and to coal’s future as part of the world’s transition to cleaner energy pathways,” Ferguson said.

“It is also important for the oil and gas industry and our energy intensive industries. Projects such as Gorgon LNG in Western Australia have enormous potential to create jobs, exports and long-term economic growth at a time when we need it most, but CCS technology is crucial to its success.”

The initial release areas are located across five offshore basins adjacent to Victoria, South Australia, Western Australia and the Northern Territory.

“The release of 10 offshore areas for assessment of their commercially viable greenhouse gas storage formations provides industry with the opportunity to plan for CCS businesses in Australia as industrial CO₂ streams become available for storage through the deployment of capture technologies over time.”

According to the Minister, the announcement follows on from legislation for greenhouse gas storage last year, the Australian Government’s $500 million investment in low emissions coal technology, and its establishment of the Global Carbon Capture and Storage Institute to drive 20 CCS demonstration projects by 2020.

“The 10 greenhouse gas storage assessment areas being released today have been identified as having the best potential in terms of geological suitability and current industry needs and are underpinned by technical data from Geoscience Australia,” he said.

CATERPILLAR has launched its new Center-Lock Pin-Grabber coupler for Cat hydraulic excavator models 311 through 385.

The mining equipment manufacturer says technology uses a patented over-center locking mechanism and two hydraulic locking features to assure positive work-tool attachment.

The new over-center locking technology promotes jobsite safety and allows operators to quickly, simply and confidently engage and disengage work tools regardless of boom and stick position.

When the operator uses an in-cab switch to engage the Center-Lock coupler with a work tool, the coupler’s robust cylinder extends to close the primary hook around the tool’s rear pin. As the cylinder rod continues to close around the rear pin, the cylinder housing adjusts its position and forces a combination of three attached parts—center-lock rocker, connector link and secondary lock—to snap into an over-center position (much like closing the handles of locking pliers). This action forces the secondary lock to grip the forward pin.

Once the coupler locks, the mechanical principles involved in its over-center locking technology assure that any working forces applied to the pins will serve only to increase the coupler’s grip. Constant hydraulic force exerted by the cylinder and the action of a counterbalance valve provide additional locking forces, supplementing that of the mechanical lock.

The Center-Lock coupler remains positively closed until the operator takes the deliberate actions of activating the in-cab switch and extending the bucket cylinder. For the operator’s convenience and for jobsite safety, the secondary lock is distinctly visible from the cab and provides an unmistakable indicator of the coupler’s status—whether locked or unlocked.

Caterpillar claims the operator no longer needs to completely curl the boom and stick (thus inverting the coupler) when engaging a work tool because the new Center-Lock coupler eliminates the blocking bar and spring pack required with conventional pin-grabber designs. The Center-Lock design requires only that the bucket cylinder be extended to activate locking and unlocking functions, and this action is independent of boom and stick position. The resulting advantage is that the operator can engage and disengage tools with the boom and stick at full extension, a valuable feature when changing tools in low-overhead situations, such as near power lines.

FLUID Components International (FCI) has released its GF90 Flare Gas Flow Meter suitable for blast applications in the mining industry.

The GF90 Flare Gas Flow Meter is designed to solve the problem of measuring dangerous, explosive and toxic gases that often flow at extremely varying and/or low levels.

Fluid Components says a highly sensitive thermal mass flow sensing element allows the GF90 to precisely measure gases of varying hydrocarbon composition.

The flow meter accurately measures combustible hydrocarbon waste gases for flare system disposal. It ensures that these dangerous by-products are safely and efficiently eliminated from the environment with minimal pollution.

Fluid Components says the disposal of flare gases protects people, equipment and complies with air quality regulations.

The meter can be specified with corrosion and abrasion-resistant alloys, including Hastelloy, Monel and tantalum, and with all-welded construction for service in the harshest environments. The GF90 Flare Gas Flow Meter operates at temperatures from -73 to 454ºC and pressures to 69 bar (g).
