Keestrack to showcase crushing solutions at CONEXPO-CON/AGG
Attendees can take a closer look at the K6 scalper, the B4 jaw crusher, and the R5 impact crusher
CONEXPO-CON/AGG, one of the largest construction trade show in North America, will take place from March 3-7, 2026, in Las Vegas, Nevada. At this major industry event, Keestrack will highlight its commitment to profitable and sustainable mobile processing solutions for the aggregates, recycling, and mining industries.
K6 scalper
In 2026, Keestrack celebrates 30 years of scalping technology with the machine that started it all: the K6 scalper.
The K6 is one of the most mature and productive scalpers produced by Keestrack, known for its performance and continuous innovation driven by decades of R&D. Equipped with a heavy-duty plate apron feeder, hydraulically folding hopper walls, load sensing hydraulics, and a long, wide screening deck, the K6 is perfectly suited for applications ranging from coarse scalping to fine screening.
Ample service access further enhances operational efficiency. At CONEXPO-CON/AGG, the K6 will be presented in a special anniversary livery, marking this important milestone in Keestrack's history.
B4 jaw cursher
The Keestrack B4 jaw crusher is engineered for heavy-duty recycling applications. Its Non-Stop System with hydraulic gap adjustment allows the crusher to open automatically when uncrushable material enters the chamber and then reset itself hydraulically. During operation, the closed side setting (CSS) is continuously monitored and automatically adjusted to ensure consistent, high-quality output.
Designed for maximum productivity and low operating costs, the B4 features a heavy-duty hopper with hydraulically folding hopper walls and a secure locking system, allowing easy loading by excavators or wheel loaders. The vibrating feeder automatically regulates the feed to maintain an optimal crusher load of approximately 80 percent.
A long, independent two-deck prescreen ensures high crushing capacities of up to 400 tons per hour while significantly reducing wear. Prescreened fractions can bypass the crusher or be stockpiled separately using the optional side conveyor.
The B4 has a feed opening of 43 inches x 27.5 inches and accepts feed sizes up to 24 inches. The CSS ranges from 1-three-quarter inches to 6-one-third inches, even with worn jaws. Automatic wear compensation is activated every 50 operating hours to maintain consistent end-product quality, with manual adjustment available if required.
Maintenance is simplified through excellent service access, with walkways, doors, and panels on all sides. The hydraulic sliding hopper frame further improves access beneath the feeder and scalping unit.
R5 impact crusher
The Keestrack R5 impact crusher, featuring the a heavy rotor in, combines reliability, compact dimensions, and high productivity. The machine is transportable as one complete unit, including a double-deck after screen, and can be set up quickly without support legs.
With crushing capacities of up to 350 tons per hour, the R5 delivers a superior cubical end-product with reduced wear, with its independently driven two-deck prescreen. This feature makes the R5 highly versatile for applications in recycling, aggregates production, quarrying, and mining.
The swiveling oversize return conveyor can be converted into a stockpile conveyor within minutes. Optional features such as a two-deck after screen, wind sifter, and magnetic separator allow the R5 to function as a complete mobile processing plant.
The R5 is available in diesel-hydraulic or full-electric plug-in versions. The electric model includes a plug-out connection to power additional equipment and can be operated either with an onboard diesel generator or as a ZERO drive, without any combustion engine on board.
