Haver & Boecker Niagara Engineers the Largest Vibrating Grizzly Screen in the World


Haver & Boecker Niagara recently announced they have custom-engineered the largest vibrating grizzly screen in the world for a large Brazilian iron ore operation.

Manufactured with Hardox® steel perforated plates and grizzly bars, the Niagara XL-Class vibrating grizzly screen boasts a capacity of 8,000 t/h and a cut size of 200 mm.

As the largest exciter-driven machine in the industry, the XL-Class provides the operation with high-capacity screening while maximizing uptime and production. Combined with the grizzly technology, the XL-Class offers the necessary ability to remove large stones, relieving pressure on the primary crusher.

Effectively screening material top sizes of 1.3 m, the XL-Class grizzly vibrating screen removes oversized materials to relieve the crusher.

Haver & Boecker Niagara listened to the operation’s challenges and employed their signature NIAflow plant simulation software to address them. The software analyzed the proposed plans, processes, goals and material for plant optimization, providing information to the customer and Haver & Boecker Niagara to design and custom engineer the one-deck vibrating grizzly screen.

To maximize uptime, the customer opted to equip the XL-Class vibrating grizzly screen with Haver & Boecker Niagara’s signature Pulse condition monitoring (Pulse CM) system. It provides the producer with 24/7 access to the health of its vibrating screen. Pulse CM includes up to 20 sensors placed on the bearings and bodies, which continually assess the acceleration of the machine and provide a forecast of the equipment’s dynamic condition in intervals of 48 hours, 5 days and 4 weeks. Additionally, they capture real-time information and send e-mail alerts at the first sign of system anomalies. The collected data provides insights into preventive maintenance opportunities, the ability to catch possible issues before they cause unplanned downtime and the peace of mind that the machine is running at peak efficiency.

“Our goal is not only to provide our customers with top-tier equipment but to act as a true consultant and partner to them,” said Clayton Carvalho, managing director of Haver & Boecker Niagara’s Brazil operation. “With more than 150 years of experience in the mining and aggregates industry, we are proud of the equipment and technology that we can offer as well as the knowledge and expert service we bring to our customers.”
