Conexpo-Con/Agg 2020: Effective mobile processing from Keestrack
Keestrack will be presenting their full range of diesel and electric mobile processing equipment
PARTICIPATING at Conexpo-Con/Agg for the sixth time, Keestrack will once again present their full-line programme of mobile processing equipment for the recycling and aggregates industry.
Highlighting the heavy range will be the Keestrack H6e full hybrid cone crusher for secondary and tertiary crushing. With a maximum feed size of 215mm and variable crushing chamber configurations and stroke settings, the specially adapted cone crusher, based on proven Sandvik technology, can processes up to 440 tonnes/h.
The powerful e-motors for the crusher drive and plant hydraulic (220kW and 2 x 30kW respectively) and all other directly electric-driven components are powered by a detachable power unit that includes an onboard diesel engine and generator (345kW/500kVa) or plug-in via mains or external genset. An optional three-deck post-screen module with oversize recirculation ensures high-quality end products. With all options fitted, the machine weighs 68 tonnes (56 tonnes without three-deck screen).
Designed for hard stone and recycling applications, the diesel-hydraulic Keestrack B4 primary jaw crusher – also available as full hybrid electric plug-in version B4e – accepts a maximum feed size of 600mm and has a feed capacity of up to 400 tonnes/h.
Integrated pre-screening, a feed opening of 1,100mm x 700mm, closed-side settings of 45–160mm and automatic hydraulic gap adjustment ensure efficient production of defined end products. An ultra-sonic sensor provides optimal feed control, while the patented NSS auto-release system and reversible jaw movement ensure continuous production.
The company’s impactor range will be represented by the 30-tonne Keestrack R3 in its new award-winning design. Available as diesel-hydraulic or fully hybrid e-version, the plant combines compact transport dimensions and low weight with production rates of up to 250 tonnes/h, making it well suited to short-term construction site operations or flexible semi-stationary production at medium-sized recycling companies or aggregates suppliers. An optional single-deck post-screen unit (9ft x 4ft) with recirculation conveyor optimizes machine performance for the production of high-grade final product.
Keestrack will also be presenting their new S1e semi-mobile, plug-in electric feeder/stacker. Installed on a height-adjustable pedestal with lifting and 180-degree swivel hydraulics, the 6-tonne machine features a 39ft 4in conveyor capable of handling up to 200 tonnes/h of material with a feed size up to 200mm. Monitored by an ultrasonic sensor, the stacker swivels automatically to create radial stockpiles pf up to 2,900 tonnes, thereby minimizing loader traffic, labour and fuel costs and optimizing on-site safety.
