Keestrack adds three new models to North American line-up

First published at CONEXPO-CON/AGG - March 13, 2020

Mobile crushing and screening company Keestrack has launched three new models onto the North American market, including its heavy 56tonne H6e cone crusher.

The full hybrid diesel/electric drive H6e can be used for secondary and tertiary crushing. With a maximum feed size of 215 mm, variable crushing chamber configurations and stroke settings, the specially adapted cone Keestrack KT-H6 is based on Sandvik technology and processes up to 440tonnes per hour (tph) of raw materials.

The powerful e-motors for the crusher drive, plant hydraulic (220 kW / 2 x 30 kW) and all other directly electric-driven components are powered by the detachable “drop-off” power unit, including onboard-diesel and generator (345 kW / 500 kVa) or plug-in via mains or external gen set.

An optional three-deck, post-screen module (total 24.5 m²/ 2.638 ft² surface) with oversize recirculation is designed to provide high-quality end products and high added value. With only 68tonnes total weight with all options (56tonnes without three-deck screen), Keestrack says the large cone can be operated economically at various jobsites.

Also making their debuts on the North American market are the S1e conveyor and R3 impact crusher.

The S1e stockpile handling solution is a semi-mobile plug-in electric feeder/stacker. Installed on a height-adjustable pedestal with lifting and 180° swivel hydraulics, the light equipment (6tonnes) has a conveyor which moves up to 200tph of crushed material, sand or gravel (maximum feed size: 200mm).

Monitored by an ultrasonic sensor, the stacker swivels automatically to create radial stockpiles up to 2,900tonnes, which is designed to minimise loader traffic, labour and fuel costs and optimise on-site safety. The S1e can be relocated via fork-lift, and can also be supplied by plug-out connections of other brands, mains or gen-sets.

The 30tonne R3 is available as diesel-hydraulic or a hybrid ‘e’-version, and combines compact transport dimensions and low weight with high production rates up to 250tph. Keestrack says this makes it a perfect solution for short-term, construction-site operations or flexible semi-stationary production at medium-sized recycling companies or aggregates suppliers.

The flexible processing of a large variety of raw and recycling materials is achieved by efficient pre-screening and the high-performance impact crusher 48 ICR 100-00 with 770mm x 960mm inlet opening, a heavy-duty 920mm rotor (diameter: 1100 mm, 3200 kg) and high rotor speeds.
