Trio crushes into smaller quarries

TEREX MPS ‘MAKES NEW TRACKS’

Crushing and screening equipment maker Trio reports that smaller independent quarries and concrete recycling operations in Africa and the Middle East are quickly responding to an insatiable need for construction materials by using its crushing and screening gear. JD Singleton, general manager responsi- ble for Trio products at Weir Minerals Africa, says these markets need equipment that can be deployed rapidly to take full advantage of infrastructure and private property develop- ments under way in their surroundings. “All the crushers and screens in the Trio range can be mounted on skids, doing away with the need for large civil-related infrastructure to support these plants,” says Singleton. “Furthermore, all the common models of jaw crushers, cone crushers, grizzly and belt feeders, vertical shaft impact crushers, horizontal shaft impact crushers, conveyor sections and hoppers are kept in stock in Johannesburg. This allows us to service the market with very short lead times, if not same day delivery.” The company’s products are also said to be cost competitive and easy to maintain on site, two more traits that are driving an increasing installed base throughout Africa and the Middle East. However, it is also Weir Minerals Africa’s strong presence in the mining regions on the continent and the Middle East that is driving the growth of these solutions. Singleton says the company is investing significantly into augmenting technical aftersales support and infrastructure in these growth areas. “These operations are very aware of the prominent role that we have played in the The need to crush and make the most of all available material has prompted quarry operators to look at ways of profiting from “waste material” that may be simply piled up for spoil in the quarry. To obtain the desired sizes in the shortest time possible, while maximising the operating profitability per cubic metre, there is need to have agile equipment, able to move without problems and reach areas where only excavators can go. To respond to these needs, MB Crusher says it has developed a range of bucket crushers and screeners designed specifically for quarry sites. The three models comprise the BF 135.8 bucket crusher, which is suitable for excavators from 43 t; the BF 150.10 bucket crusher, ideal for excavators with over 70 t operating weight; and the MB- S23 screening bucket, said to be a success in

Turkey, Bilecik Marble Quarry is using the BF135.8 bucket crushers not only to assist in mining activities, but also to shatter the material required for the rehabilitation of the quarry roads. The considerable advantage, guaranteed by the versatility of the equip- ment, is that the material is crushed where it is needed, without having to employ a unit for transport. As a result, the slopes of the quarry are always pristine, with positive impact on the maintenance of the quarry machines and, in general, the productivity of the operation. The BF135.8 has a max- imum production of 88 m³ per hour and a loading capacity of 1,6 m. b Meanwhile, the LC450 incorporates the Cedarapids MVP450X all roller bearing cone crusher. The cone crusher comes with a hydraulic, maintenance free, anti-spin device that helps improve cone liner wear life, as well as a hydraulic tramp overload protection system, TIR, that helps clear the crushing chamber of any potential tramp metal that may have entered the crusher with the feed material. The LC450 tracked cone crusher also incorporates an automated metal detection system, located on the heavy duty feed conveyor, which stops the conveyor before the metal contaminant reaches the crusher. The plant also has the patented metal purge system that reduces downtime when removing the metal contaminate from the feed conveyor. b Terex Minerals Processing Systems (MPS) launched its ‘Making New Tracks’ large mobile plant strategy at MINExpo Inter- national Show in Las Vegas, on 26-28 September 2015. “We have three new large tracked mobile plants which enable Terex MPS to diversify further from our modular, portable and static offerings. With over 100 years in the indus- try we now have a strong product portfolio offering customers from a wide range of in- dustries, cost-effective solutions for the long term,” says David Quail, Terex MPS market area director for Americas. Terex MPS’s LJ5532 comes with its famous Terex JW55 single toggle heavy duty jaw crusher mounted on a tracked chassis. The hydraulically adjusted jaw crusher, requiring no shim packing, allows the CSS of the jaw to be adjusted in a matter of seconds. The LJ3255 features an independent pre- screen, located before the crusher, which helps bypass or remove any undersized ma- terial or feed material that has a high content of dirty fines, thereby promoting maximum throughput performance, as well as enhanc- ing the heavy duty manganese wear life.

formal mining industry for many years, and understand the value we are able to bring to their operations,” he says. While the demand for aggregate and sand production continues to grow, Rasheel Sukdhoe, product manager for Trio crushers at Weir Minerals Africa, says Trio solutions are also being used in concrete recycling and slag processing operations. Trio products can easily be commissioned on building and landfill sites, as well as on mine waste rock dumps. Sukdhoe says that since acquiring the Trio group of companies in 2014, Weir Minerals has been investing significantly into enhancing the offering. This is reflected by the launch of the Trio TP range of cone crushers which incorpo- rates a higher pivot point, thus providing more crushing action and increasing the percentage product passing the closed side setting. “The design features a steep crush- ing chamber angle, a large crushing stroke and optimum speed to deliver a finer product through increased inter-particle comminu- tion,” says Sukdhoe. b

MB bucket crushers save the day

quarries around the world. The MB-S23 is claimed to be the largest screening bucket in the world with a load capacity of 4,3 m³ and a depth of 1 490 mm basket well. MB reports that it has made strong in- roads with its bucket crushers across many quarries globally. For example, in northern Suitable for excavators from 43 t, the BF135.8 has a maximum production of 88 m³ per hour.
