Keestrack, a mineral processing equipment manufacturer with U.S. offices in Krum, Texas, has released its H6e cone crusher. Similar to the Keestrack H4e introduced in 2016, the H6e is a new 62-ton fully hybrid machine.
The H6e 400-tons-per-hour model has a maximum feed size of 8 inches. Its driven by a 220-kilowatt electric motor. The lubrication system, the 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 is designed to also load personnel in excavators or loaders to operate the machine by means of a remote control unit. As an option, Keestrack-er, a satellite-based telemonitoring system, is designed to document all the key performance 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.
The entire drive unit is designed as a removable module. 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 supply from the mains or additional generator as a standard.
A hydraulically driven belt feeder with integrated metal detector feeds material from the hopper with load-release device for the equal distribution of the feedstock. The main discharge conveyor offers a stockpiling capacity of 350 tons without postscreening. The optional H6e postscreen module includes a screen box with a sensor-monitored hydraulic drive.
