Guardian Dust Binder is the latest technology developed by RST to support the mining industry with an economical, mulঞ-purpose product suitable to most applicaঞons, materials and climates. An easy, versaঞle soluঞon for a whole range of dust and sediment issues, Guardian Dust Binder is highly effecঞve in dust and erosion miঞgaঞon acঞviঞes, with addiঞonal benefits including; a reducঞon in water consumpঞon, extended ঞme between repeat water applicaঞons, fleet opঞmisaঞon, operaঞonal savings and the ability to meet environmental obligaঞons. RST Operaঞons and Technical Director David Handel said the company was achieving posiঞve outcomes for clients through the development of effecঞve, cuমng-edge soluঞons that were economically viable and easy to use. "We have been able to develop dust suppressants that are super concentrated and highly effecঞve through our conঞnual improvement programs and strategic alliances that provide us with the data to develop these leading-edge soluঞons," he said. "It is about finding the most cost-effecঞve soluঞon that achieves the best immediate and long-term results." Easy for operators to store and apply, Guardian Dust Binder dissolves quickly in water for treaঞng unpaved roads, stockpiles, tailing dams, waste dumps and land rehabilitaঞon works. Guardian Dust Binder is applied to the water in water carts and spray systems to significantly reduce water consumpঞon by maximising absorpঞon and decreasing evaporaঞon. "We recognised a need for an easy, economical dust control soluঞon that can be adjusted to suit a range of applicaঞons and for short- and long-term treatment," Mr Handel said. "Once Guardian is applied, operators can monitor the site and adjust the dosage to find the ideal soluঞon moving forward." RST's range of products are formulated using the latest technologies in organic and inorganic polymers, and include crusঞng agents that coat fine parঞcles, binders for dust and sediment control soluঞons and weমng agents for achieve maximum material compacঞon. RST launches new advanced formula guardian for treating dust, sediment and erosion The Cat ® 797F large mining truck is now available in a fuel-efficient configuraঞon that meets US EPA Tier 4 Final emissions standards. Through more than 16,000 hours of successful pilot machine operaঞon and 100,000 hours of producঞon truck operaঞon in Tier 4 configuraঞon, the system has proven its ability to deliver strong performance and greater fuel efficiency compared to the Tier 2 797F in most applicaঞons. The 797F Tier 4 Final is equipped with an exhaust a[ertreatment system featuring selecঞve catalyঞc reducঞon (SCR), which uses diesel exhaust fluid (DEF) to lower NO x emissions. This Cat emissions plaorm is proven through more than 20 million operaঞng hours in the field. To maintain superior reliability, the 797F a[ertreatment system uses less than 11 percent new content. Designed for easy serviceability with readily accessible components, the modular a[ertreatment system is aligned with truck prevenঞve maintenance intervals to maintain high availability. The best-selling truck in the 400-ton (363-tonne) size class, the 797F is powered by the 4000-hp (2 983-kW) Cat ® C175-20 engine, available with opঞmized fuel maps for customers focused on the lowest fuel burn, Tier 2 equivalent raঞng, and now Tier 4 Final. Known for delivering class- leading payload and speed-on-grade performance, the 797F delivers the same producঞon performance in Tier 2 and Tier 4 Final configuraঞons. Beyond offering similar performance, the Tier 4 Final 797F reduces total specific fluid consumpঞon costs (fuel plus DEF) in most applicaঞons. Lower fuel burn results in longer engine life and lower repair costs. Field evaluaঞons of the low-emissions 797F included a wide range of applicaঞons, including oil sands, deep pit copper, iron ore and coal. The trucks exceeded producঞon targets and demonstrated strong engine performance in all applicaঞons, including sites with extreme ambient temperatures as well as some with alঞtudes greater than 16,000 [ (4,877 metres).
