Keestrack debuted the H6e cone crusher, which is an expansion of the company’s mobile cone crusher series.

The company says the H6e has a maximum feed size of 215 mm, variable crushing chamber configurations and stroke settings that allow for a wide closed-side-setting range of 6 to 44 mm. Also, the drive and control technology have been adapted in line with the company’s hybrid concept.

Additionally, the crusher is driven by a 220-kW electric motor. The lubrication system, hydraulic 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 personnel in excavators or loaders to operate the crusher by means of a remote-control unit.

A 345-kW Volvo diesel engine with a connected 500-kVA generator supplies the onboard energy. The entire drive unit is designed as a removable module. The Keestrack H6e also offers plug-in power supply from the mains or additional generator, making it possible to reduce direct energy costs by up to 70 percent, the company says.

The H6e features a 1200-mm-wide hydraulically driven belt feeder with integrated metal detector that feeds material from the 8-m hopper with load-release device for the equal distribution of the feed. The main discharge conveyor has an 11-kW electric drive motor and reaches a drop/transfer height of 4,800 mm, offering a stockpiling capacity of 350 tons without post-screening, says the company.

The screen box, with a total screening area of 24.5 m over three decks, has a sensor-monitored hydraulic drive, with all belts powered by electric drum drives. Providing large stockpiling capacity during operation, the discharge conveyors can be fully retracted for transport.
