Haver & Boecker Niagara's N-Class offers one to three screen decks and features an advanced single-eccentric shaft design
Haver & Boecker Niagara says its new rugged N-Class vibrating screen can optimise crushing plants and screening operations through its ability to screen as much as 5,000tonnes/hour. It is said to be ideal for tough jobs, such as scalping and classifying ores, minerals, stones, sand and gravel in aggregates and mining applications. The Niagara N-Class vibrating screen has an advanced four-bearing design that is said to minimise structural vibration while maintaining constant g-force, even through fluctuating material feed rates.


“The Niagara N-Class is a one-of-a-kind machine with the ability to productively accomplish screening tasks other vibrating screens have difficulty with,” said Peter Grotjohann, managing director of Haver & Boecker Niagara’s 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 said to be dynamically 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 is said to “virtually eliminate” 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 screens offer a self-cleaning action to minimise common problems encountered with traditional grizzly feeders.

The N-Class is described as ideal for reducing loads and energy demands for a crushing plant by providing more consistently-sized material to improve crushing efficiency. The use of the vibrating screen in the process before the crusher increases the crusher capacity and maximises the quality of the crushed product.
