Keestrack’s new H6e for high-end mobile secondary crushing

Keestrack, an international specialist in min- eral processing technology, has expanded its range of track-mounted machines for the manufacture of high-grade final grain prod- ucts with the launch of its H6e cone crusher. Similar to the Keestrack H4e introduced in 2016, the new 62 t fully hybrid machine is said to be based on the market’s leading crushing technology, together with an inno- vative diesel-electric drive concept, enabling full flexibility at maximum cost efficiency. Keestrack announced the expansion of the new series at least a year ago, shortly after the successful launch of its fully hybrid H4e cone crusher, approximately 46 t, with a maximum production capacity of 250 t/h. That is now followed by the Keestrack H6e 400 t/h model. A maximum feed size of 215 mm and very variable crushing chamber configurations and stroke settings enable the Keestrack KT-H6 to offer a wide CSS range from 6 to 44 mm, while the drive and control technology have been specially adapted in line with the Keestrack hybrid concept. The crusher is driven by a 220 kW electric motor – the lubrication system, the hydraulic As part of its focus on offering a compre- hensive portfolio of products to address the needs of the compact crushing and screen- ing market, EvoQuip has now launched its new Bison 280 jaw crusher. It is suited for a range of applications including construction & demolition, asphalt recycling and quarry- ing or contract crushing. The EvoQuip Bison 280 has since been tested in a tough granite site at Peter

supplies the onboard energy. The entire drive unit is designed as a removable module, as now is the case for the smaller H4e machine. Located remotely from the crushing plant, dust and vibration levels can be clearly re- duced, maintenance access can be facilitated and hence the availability and service life of the drive unit can be clearly optimised. All the crusher operating functions remain active, including the 63A connector for add- on screening units or stockpile conveyors. The Keestrack H6e also offers plug-in power sup- ply from the mains or additional generator as a standard, making it possible to reduce direct energy costs by up to 70%. b that offers versatility with supreme durabil- ity while also providing our customers with excellent productivity and fuel efficiency. The quick set up times, simple intuitive operation and ease of transport makes this machine an ideal solution for all applica- tions,” says Matt Dickson, product line director at EvoQuip. The rapid set up time and intuitive control system on the EvoQuip Bison 280 enables the operator to be crushing minutes after unloading the machine from the lorry. The operator can also adjust the crusher setting easily without the need for any tools using the user friendly hydraulic jaw adjustment system. The EvoQuip Bison 280 offers sound flexibility as it can be used on a multitude of natural stone applications including granite, river gravel and basalt. It can also be used on various recycling applications including construction and demolition waste, recycled concrete, reclaimed railway sleepers. There are a number of key design features in the Bison 280 that ensure an optimal ma- terial flow throughout the crushing process. The vibrating feeder automatically regulates the flow of material into the crusher based on the engine load and this ensures that an optimal choke feed is kept in the jaw. b

Hydroset control with overload cut-out and the air compression of the crusher housing are powered by separate electric motors/ pump units. All crusher functions are incorporated into the central Keestrack PLC controller, which also enables loading per- sonnel in excavators or loaders to operate the machine by means of a remote control unit. As an option, Keestrack-er satellite-based telemonitoring documents all the key perfor- mance data of the crusher in real-time, alerts the operator to any malfunctions and collects the current production data if a belt-scale is installed (optional).

MD Peter O’Donnell says the productivity and performance of the EvoQuip Bison 280 has surpassed the quarry management’s expec- tations. “While the machine itself is very compact it is definitely not a lightweight ma- chine as it consistently produced a quality product at a high throughput and low cost per tonne in our quarry”. “The Bison 280 jaw crusher is a machine
