Leading global equipment manufacturer Astec Industries is shaping the future of quarrying with equipment that combines strength and durability with the latest technology and innovation.
Once regarded as low-tech, the quarrying industry today is embracing new technologies and pioneering methods to drive efficiency, safety and sustainability. Quarries are demanding more features, benefits and flexibility than ever from their equipment, and just tough is no longer enough, according to Philip Saunders, product sales manager for Astec Industries’ Materials and Infrastructure Solutions divisions. Equipment like the Astec GT205S mobile screen, GT125 mobile jaw crusher and FT200DF track cone crusher fit the bill and are chosen by quarries aiming to reduce costs and increase productivity, he states.
The Astec GT205S is a powerful, adaptable screening solution designed for high-output applications, Saunders explains. “This three-deck mobile incline screen plant offers a combination of capacity, durability and customisation options, making it a valuable asset in the aggregate processing and construction industries. It is fitted with a 5 x 20 screen and a Caterpillar C4.4 129 HP Tier III diesel engine.”
High production capacity
Saunders notes that the Astec GT205S’s key benefits are its high production capacity, customisation and support, and minimal downtime. “The GT205S is designed to process large volumes of abrasive, hard rock and sand efficiently. With the ability to handle up to 600tph (or 726 metric tonnes per hour, with modifications), it is ideal for operations aiming to maximise material output.
“The Astec mobile screens team works closely with our customers, to modify equipment to meet specific production needs. Whether increasing throughput or adjusting design features, the GT205S can be tailored for optimal performance.
“With a robust design and reliable support, the GT205S experiences minimal downtime. It is estimated at under 10%, which is for standard maintenance. Quick access to parts and responsive service ensure maximum operational efficiency.”
This screening plant offers ideal hydraulic angle adjustment. This feature improves screening efficiency, especially for wet or sticky materials. It efficiently screens materials up to 102 mm in size, meeting stringent specifications for road construction and other applications. The GT205S’s large screen box enables the production of high volumes of material when producing straightforward products such as G7. But, with the three-deck four-product conveyor setup, there is an element of finesse available when coupled with the adjustable screen box, Saunders reveals. “This functionality allows the quarry to maximise high quality low yield products such as 5mm and 9.5mm surfacing stone.”
The Astec GT205S is renowned for its durability in harsh conditions. Built to withstand abrasive materials, it features strong hydraulic systems and durable components, reducing maintenance needs and extending machine life.
Mobile jaw is equally effective for aggregate and recycling applications
Astec’s GT125 mobile jaw crusher is another exceptional machine that is making its mark at quarries around the world, especially in the United States, where its applications include producing and recycling aggregate. Saunders says that it is equally effective in both these operations.
“The GT125’s large, dynamically balanced, heavy-duty flywheels produce up to 33 percent more inertia than competitive models, leading to a reduced cost per ton over the lifetime of the machine. This crusher’s large, 32mm stroke processes more material than competitive models, increasing production and reducing operating costs. A simple manual folding head section on the discharge conveyor reduces the footprint of the machine, reducing shipping costs.”
Reduce operational expenses by up to 50 percent
Quarries choosing the Astec FT200DF track cone crusher can reduce their operational expenses by up to 50 percent, Saunders states. He explains that this is made possible by the machine’s unique roller bearing design, which generates higher efficiencies. The unit also boasts a patented tramp iron relief system that protects the crusher from costly failures, he notes. “This is achieved by minimising the impact of crusher overload shock transmitted to the components. This machine offers users an ideal combination of geometry, stroke and speed which delivers an aggressive crushing action and increased capacity. This exceptional unit is permanently precision balanced with protected internal counterweights.”
The FT200DF’s other notable features include a variable-speed hydraulic drive; remote closed side setting (CSS) adjustment; interchangeable chamber configurations; field-replaceable base frame tub and V-seat liners; and a hydraulic cone brake. Its feed hopper features a level sensor and it has a 95l lube oil tank with an immersion heater.
Saunders foresees growing demand for exceptional equipment that can optimise quarrying operations – like this powerful trio from Astec Industries. “With increasing infrastructure development and road construction projects, the need for high-quality aggregates continues to grow. High performance equipment from Astec Industries will play a crucial role in meeting this demand efficiently.
“A further benefit for Astec Industries customers is the reliable support and parts availability that they can be assured of. Strong OEM and factory support are essential for maintaining uptime. The availability of parts and quick response times help keep operations running smoothly, minimising disruptions,” he concludes.
