capabilities compared to other, conical stockpilers. Engineered for surface and underground mining as well as aggregate, construction and demolition applications, Astec-BTI breakers are renowned for their reliability and design simplicity. “The simple construction of the breakers ensures reliability and low main- tenance, which make them ideal for quarries striving to manage costs. Simplicity of design is, in fact, a key element of the Astec-BTI breaker system,” Kruger notes. “The breaker’s control valve also features a simple design to minimise cavitation, thereby reducing hydraulic component wear and increasing the efficiency and lifespan,” he adds. Another noteworthy feature is the excel- lent power-to-weight ratio. “This offers sig- nificant benefits to customers, since larger, more powerful hammers can be mounted on smaller excavators or boom systems, result- ing in reduced overall cost to the end user,” states Kruger. Standard features on all models include a nitrogen cushion chamber designed to absorb piston recoil and recycle the energy to increase the output energy on the next blow, dual retainer pins to ensure positive tool alignment and easy tool replacement, short tie rods that utilise protected threads to yield long life and high reliability, and a protected lubrication point. Kruger says that mobile and fixed hydraulic rock breakers are increasingly being used for reducing oversize material, rather than secondary blasting. “Astec-BTI’s Rock Breaker Systems minimise disruptive, costly and unsafe blasting, providing an efficient, safer alternative,” he says. “Rock breakers provide for selective breaking, as opposed to the indis- criminate nature of blasting,” he adds. “This can improve material grades, which boosts sales revenue.” The Astec-BTI CX, BX and BXR range of rock breakers offer 14 models, from 550 joules to 21 500 joules energy class, with most also Telestack and Astec-BTI equipment through Astec Industries in South Africa can have peace of mind knowing that it comes with Astec’s 24/7 after-sales service, back-up and spares, Kruger says. “We have local engi- neers dedicated to these product ranges. They will assemble and commission a customer’s machine, offer operator training, service and back-up. We also hold spares, to minimise downtime and ensure that our customers can be back in business as quickly as possible. In addition, Astec engineers are able to under- take on-site repairs,” he concludes. l available in box-style configurations. Local customers purchasing Astec-

while the RSL30 delivers 450 mtph. The reduction of segregation, degradation, contamination and compaction when stockpiling with this equipment ensures ‘in specification’ material for any application. They offer 30% more stockpile capacity on the same footprint compared to standard stackers.” Available as tracked or wheeled units, with automation, dust suppression and independent power options, Astec-Telestack stackers can be used in mobile or fixed crushing and screening operations. A further benefit of Astec- Telestack’s radial telescopic stackers is that they minimise the need for wheel loaders. This translates into less site traffic, lower emissions and substantial savings on fuel and labour. The automated stockpiling option cuts staffing requirements, further reducing costs. Astec-Telestack offers the widest range of mobile conveyors in the indus- try. Machines like the Astec-Telestack TC 424XR Radial Mobile Conveyor and Feeder – which boasts a 450 mtph capacity - are designed for flexibility and can be deployed quickly across different site locations. Astec-Telestack’s Origin Wheeled conveyor range - which includes the C2000 - offers affordable wheeled stackers combined with the proven Astec-Telestack quality. Suited for short to medium term, highly mobile applications, the C2000’s versatility and portability ensure that it can meet the needs of any stockpiling application, especially in confined areas. It is particularly suited to applications where movements are frequent. Featuring a radial ability from pinned base, it offers superior stockpiling
