Haver & Boecker Niagara used bauma 2019 to unveil its N-Class vibrating screen designed to optimise crushing plants and screening operations through its ability to screen up to 5 000 tonnes per hour. The Niagara N-Class is ideal for scalping and classifying ores, minerals, stones, sand and gravel in aggregates and mining applications.
Haver & Boecker Niagara builds the equipment with an advanced four-bearing design that minimises structural vibration and maintains constant g-force even through fluctuating material feed rates.
“The Niagara N-Class has the ability to accomplish screening tasks other vibrating screens have difficulty with,” said Peter Grotjohann, managing director of the German facility. “The machine offers our customers an ideal solution for improving crushing plant efficiency and classifying coarse materials, therefore improving profits.”
Haver & Boecker Niagara’s N-Class offers one to three screen decks and features an advanced single-eccentric shaft design that’s supported by four high-performance, double-spherical roller bearings. It is balanced to minimise dynamic loads transferred into the structure and allows multiple screens to be placed side by side in the same building.
The N-Class maximises screening efficiency and eliminates blinding and pegging by providing a consistent g-force in all operational modes, regardless of load consistency. A heavy duty body design handles heavy loads in applications with extreme material sizes up to 2,032 x 1,016 x 1,016mm. The screen offers a self-cleaning action to minimise common problems encountered with traditional grizzly feeders.
