Celebrating 30 years of supplying mobile and fixed crushing and screening equipment across Australia, Screenmasters has been the distributor of the Keestrack brand of products for the past two decades. Built around the ideology “performance in every detail”, Keestrack is a global mobile crushing and screening equipment manufacturer that has grown from a family business set up in 1988 to now having an annual turnover of 100 million Euros.

With the established Australian presence thanks to Screenmasters, the R6h HSI impact crusher is one example of Keestrack machinery being successfully deployed across the country, saving customers thousands in maintenance and operating costs each month, Screenmasters says.

Hi-Quality Group – One such company is construction and quarry business Hi-Quality Group. Supplying a diverse range of products and solutions across four states and 12 sites, and employing over 250 staff, Hi-Quality operates quarries, landfills and recycling centres, selling natural rock and recycled products. Over the past couple of years Hi Quality Group has purchased several new and used Keestrack scalping and flip flow screens for recycling. However, the R6h HSI impact crusher is providing significant benefits, with the one machine replacing the need for a separate jaw crusher, cone crusher and screen set-up – allowing Hi Quality Group to produce up to four products in one pass.

Having purchased its first R6 in 2016, Hi-Quality Group recently took ownership of two new Keestrack R6h impactors for its quarry operations in NSW and Victoria. The original R6 now has 10,000 hours on the clock and still processes recycled concrete on a daily basis. It was this reliability that gave Hi Quality the confidence to move away from traditional crushing processing
methods to just running one machine, says Screenmasters. “We have replaced three crushers and one screen with one Keestrack R6h impactor to produce 20mm Class 3 road base and aggregates at a rate of 220 tonnes per hour,” Hi Quality Group crushing production manager Paul Oostendorp says. “This has allowed us to significantly reduce our fuel, maintenance, wear,
parts and labour costs, allowing us to streamline our operation. “The newer machines, with the higher horsepower engine, have blown us away with their overall performance and durability. In my opinion the Keestrack R6h is a no brainer.”

Key features – The new R6h features a series of updates to the model, including a larger 765hp (570kW) Volvo engine, which has led to an increase in overall performance and the quality
of the final product shape and sizing. Users can produce 20mm Class 2 and 3 road base with just one machine. The R6 features a 16×5 double deck screen and a 3.1m independent double deck pre-screen with fines conveyor, as well as a 6.5-tonne rotor powered directly off the engine. The R6 has a 600mm maximum feed size and a pan feeder underneath the rotor to reduce wear on the main conveyor and help prevent any conveyor stoppages. The machine comes with sealed bearings on all tail and head drums (where possible), with no daily greasing and hydraulic hosing has been replaced with steel hydraulic pipes to offer easy access for service and maintenance.

“This is just one example of a Keestrack machine changing the crushing industry and saving Australian contractors and quarry owners thousands in maintenance and operating costs every month,” Screenmasters says. “The Keestrack R6h is currently the most productive impactor on the market today in many applications, including recycling, concrete crushing, quarry and aggregate production, and is a standout in processing notoriously difficult paddock and volcanic rock.”
