N-Class scalper for heavy duty applications

Published by

The Haver & Boecker Niagara N-Class vibrating screen can screen as much as 5000 tph. The screen can scalp and classify ores, minerals, stones, sand and gravel in aggregates and mining applications.

The company builds the equipment with an advanced four bearing design that minimises structural vibration and maintains constant G-force even through fluctuating material feed rates. It also featured at Bauma 2019 in Munich.

It offers one to three screen decks and features an advanced single-eccentric shaft design that’s supported by four double-spherical roller bearings. It is 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 vibrating screen improves 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 2032 x 1016 x 1016 mm. The screens offer a self-cleaning action to minimise common problems encountered with traditional grizzly feeders.

The N-Class is 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.

Each N-Class comes equipped with Haver & Boecker’s signature Ty-Rail System, which cuts media replacement time by about 50% by simplifying the process.

Haver & Boecker Niagara builds the N-Class for quick and easy re-balancing. It includes long-life bearings and a maintenance-friendly, modular machine design. The vibrating screen is equipped with buffers between the screen box and support frame for improved process reliability.

It is recommended to equip the machine with Haver & Boecker Niagara’s patented crossbeam abrasion protection system, Snap-Guard®. Snap-Guard is made from polyurethane and protects crossbeams from harsh materials, extending maintenance intervals, reducing operating costs and increasing profits.
