Aggregate crushers, screeners, and conveyors


For the most cost effective crushing, Frontline offers Keestrack’s top impact, jaw, and cone crushers. The Keestrack R6 impact crusher is perfect for high production and high capacity, with a long aggressive pre-screen and an optional 2-deck after screen producing up to 500 tonnes an hour. For a highly compact and fuel efficient machine, the Keestrack B3 jaw crusher is a leader in its class. At a weight of under 30 tonnes, this machine can produce up to 400 tonnes/hour with feed size of 600 x 1000 mm (24 x 34”). For a job needing incredible versatility, the Keestrack H4 combines three machines in one with its optional pre-screen and dirt conveyor, 3-deck screen and cone crusher while burning only 30 - 32 litres of fuel an hour.

For screening aggregate, Frontline offers something for every step of the process. The Keestrack K6 is a high performance direct-feed scalping screen and is one of the most versatile in the industry separating 3 fractions at once with a capacity of up to 600 tonnes per hour. For heavy production, the Keestrack C4 classifier finishing screener is both heavy-duty and user-friendly. Named the best mobile-friendly screening machine in the industry, this machine weighs in at 28 tonnes, producing 400 tonnes an hour and is available in a 3 or 4 split version and ECO drive electric option.

The perfect addition to any of these is the Keestrack S5 stacker conveyor, providing 75% of cost-saving capacity compared to manual wheel loading. This machine can be set at 3 different inclinations and has a capacitance of 500 tph.
