New Cone Crusher

Metso has officially introduced the new Nordberg HP4 cone crusher to the North American market, after unveiling it in Europe last spring. The first in Nordberg’s line of high-performance cone crushers, the HP4 is said to produce much finer products with fewer crushing stages than competing units. Metso claims it combines optimized speed with a large throw to provide the highest reduction ratios of any cone crusher on the market today.

HP4 features include dual acting hydraulic tramp release cylinders that allow the unit to pass tramp iron that Metso says would stall or damage other crushers. An advanced fastening system for the mantle and bowl liner eliminates the need for backing material and makes liner changes quicker. The unit has thicker liners for longer life and Nordberg has greatly simplified the replacement procedure.

Tier 3 articulated truck debuts

Case has rolled out the Tier 3 versions of its 27-ton 327B and 30-ton 330B articulated trucks. The new models get more horsepower than the models they replace, as well as new cab ergonomics and a number of service and maintenance upgrades. Carryover features include Case’s signature integrated differential, variable geometry turbocharger, auto warmup system, and self-diagnosed fluid-level checks.

The new 10-liter Tier 3 engines feature increased fuel pressure at cylinder entry and variable-geometry turbochargers that optimize the fuel-to-air mixture for peak performance in varying conditions. Along with new cab comforts and visibility, the new models now feature a new front suspension system to absorb shocks from rough terrain and to provide a more comfortable ride. The new front driveline features an integrated transmission-mounted differential that transfers power directly from the transmission to the front wheels, eliminating a drive shaft as well as noise and vibration.

Leak-free hydraulic couplings

Holmbury says its new RoFLEX 5000 line of high-pressure hydraulic couplings is designed for severe breaker and sheer applications and offers the industry’s longest warranty. The screw couplings can be connected and disconnected under pressure and offer a one-year warranty against leakage. Holmbury says they will last for years — even in severe applications.

Aggressive pre-cleaner

Martin Engineering heralds its new Martin Pit Viper sand and gravel belt cleaner as an aggressive pre-cleaner specifically engineered for applications in the aggregate industry. The company describes it as an economical package that will remove sticky sand and wet fines on belts from dredges, sand screws, and other sand processing operations, as well as withstand abrasive rock chips and dust remaining on the belt in crushed stone plants. Features include a one-piece urethane blade that contains about 20 percent more urethane than other pre-cleaners and is set at an aggressive angle of attack to increase efficiency. Blade replacement requires no tools — the new blade drops in place onto the cleaner’s steel mainframe and is secured with a wire lockpin.
