Niagara XL-Class Vibrating Screens produce up to 15000 tons per hour

Haver & Boecker Niagara offers the Niagara XL-Class vibrating screen, which combines advanced exciter drive technology with a wide body to offer producers high-capacity screening action at up to 15,000 tons per hour.

The XL-Class is the largest exciter-driven machine in the industry. It is ideal for high tonnage rates, such as iron ore and oil sands applications. Each XL-Class  machine is custom-designed to its specific application using Finite Element Analysis (FEA) to predict the structural behaviour of a vibrating screen.

With more than 15 years of FEA and experimental measurement experience — and nearly 400 high-capacity vibrating screens supplied to the global market — Haver & Boecker Niagara is able to provide state-of-the-art high-capacity vibrating screens that offer easy operation, low maintenance and unmatched reliability.

“Haver & Boecker Niagara is dedicated to using innovative technological solutions to enhance customers’ daily processes,” said Eduardo Iizuka, Haver & Boecker Niagara chief engineer of product development. “Our ability to optimize the XL-Class to perform at peak efficiency, according to exact application requirements, provides a reliable, low-maintenance screening solution for our customers.”

Haver & Boecker Niagara strategically engineers the XL-Class vibrating screen using FEA, which predicts high stress areas and natural frequencies. FEA is a numerical simulation tool used by Haver & Boecker Niagara engineers to assess the structural behaviour of a vibrating screen. The analysis equips engineers with the appropriate information to understand the machine’s expected performance, determine where to reinforce critical areas of the vibrating screen and reduce the weight of oversized components, resulting in an optimized vibrating screen. Haver & Boecker Niagara then customizes each XL-Class to perform at maximum productivity according to a producer’s specific application requirements.

The vibrating screen features a robust, maintenance-friendly design. The fully-bolted, nonwelded construction of XL-Class side plates eliminates the possibility of stress concentrations from welding. The machine’s large deck size maximizes feed rates, enabling the machine to effectively handle production rates as high as 15,000 tons per hour and cut sizes from 48 mesh to 10 inches. The overhead, bridge-mounted drive system does not interfere with the material flow path, reducing the wear potential that shaft-driven machines experience.

The XL-Class is sloped from -3 to 10 degrees offering operations further flexibility. The negative angle allows the horizontal screen to be used in dewatering applications. The declined installation angle uses the force of gravity to keep the water back, while the linear action throws the material forward down the deck. The decline also allows a material bed to be built up, which acts like a filter cake to capture the fines and allows the water to pass through. Additionally, the inclination option increases the material velocity to decrease layer depths and allow for a more efficient separation of fines from the coarse material, resulting in increased material flow and maximum production.

Unlike other manufacturers, Haver & Boecker Niagara manufacturers their own brand of Niagara Exciters which come standard on all new XL-Class vibrating screens. The bridge-mounted exciters are available in four models to improve screening performance, and offer the largest static moment range on the market. Due to the exciters’ strength and advanced sealing system, Niagara Exciters offer producers minimal maintenance and an extended service life for up to 50,000 hours. Producers can purchase Niagara Exciters for use on any brand of exciter-driven vibrating screen.

All Haver & Boecker Niagara vibrating screens undergo extensive testing, inspection and the industry-leading Pulse vibration analysis prior to shipping to ensure correct balance and smooth operation. For added security, new XL-Class purchases are eligible for the industry’s only 3-year Uptime warranty. Uptime includes Haver & Boecker Niagara’s signature PROcheck consultation and offers customers a full-service approach to prevent unscheduled maintenance and extend the life of the vibrating screen. It includes parts inspection, equipment assessment and a screen media evaluation, resulting in a fully optimized screening operation.
