At Sandvik Mining and Construction’s customer event last October at the Eureka Stone Quarry in Pennsylvania, the company presented more than 20 of their latest machines for aggregate and construction operations, including mobile crushers, drills, breakers and more. New products launched at the event are described below.
QE440 Scalper. The latest and largest of the company’s mobile screeners is the new QE440 Scalper. The QE440 sets new throughput standards for the industry with over 40 percent greater screening area than the former market leader, the QE340. The machine features stockpiling conveyors that are both wider and higher to deliver increase production capacity and offer the convenience of larger stockpiles.
CR810 Hybrid Crusher. This roll crusher is just one of the several new models added to the Sandvik line through its continuing acquisition strategy. The CR81 is well suited for primary and secondary crushing of soft to medium-hard materials, as well as wet and sticky ones. It features a compact design that reduces the space requirements within the crushing plant. The CR810 is designed with advanced crushing technology, such as the hydraulic gap adjustment and the overload protection, combined in one machine. The large space between the teeth of the rollers makes the CR810 generate a high quality output product containing a minimum of fines.
DP1500i Drill. Several drills were shown, including Sandvik’s latest “intelligent” drill, the new DP1500i. The DP1500i is a hydraulic, self-propelled, crawler-based top-hammer drilling rig. The model is fully equipped with controls and monitors providing information on the condition of the drill and the work performed. The drill features an innovative drilling parameter set up, advanced ROPS/FOPS certified safety cabin, and excellent visibility.
Breakers. The new BR2577 hammer offers has the latest in breaker design with Sandvik’s innovative FBE (Fixed Blow Energy) system, ensuring maximum impact in every blow. In addition, it features Sandvik’s VIDAT (Vibration Dampening Tie Rod) system, ensuring greater reliability, and lower operating costs.
The BR4099 breaker features significantly enhanced hydraulics. At the event, Sandvik operators demonstrated the model’s idle-blow selector. This easy setting switches the hammer between high-frequency/low energy-action, or low-frequency/high-energy action, allowing the operator to get the most performance possible in a wide range of material. With the new designs, Sandvik has lengthened the service intervals from 600 out to 1,000 hours.
