Niagara F-Class Vibrating Screen

Haver & Boecker Niagara has revolutionized its signature Niagara F-Class vibrating screen with new technology for simplified maintenance combined with maximum performance and longevity. The new design retains the technical benefits the original F-Class is known for, such as improving performance in material stratification and reducing blinding and pegging.

“Our new design results in a more durable and easy-to-maintain vibrating screen with the same industry-leading performance customers expect from the F-Class,” said Duncan High, the product manager behind Haver & Boecker Niagara’s new F-Class design.

The vibrating screen is now primarily manufactured with vibration-resistant lockbolts instead of the traditional welding used in previous designs. Lockbolts are more effective at maintaining structural integrity during the demanding load-bearing, high-vibration operation of a vibrating screen, while making maintenance more convenient, safer and cost-effective. Bar rails are now fastened to the cross beams with lockbolts, making them easy to exchange if they become worn. The robustness of the machine also permits cross beams to be positioned and lock-bolted every four-feet instead of every two-feet, allowing for better clearance and easier maintenance.

The new F-Class design provides the option to upgrade the machine with Haver & Boecker Niagara’s new Drop Guard system. The liners provide protection for the machine’s cross beams, both reducing wear and extending vibrating screen life. The blue liner simply drops over the cross beam with no adhesive or tools required, making installation quick and easy.

Additionally, Haver & Boecker Niagara redesigned the flat deck models of the new F-Class to create the largest amount of open area possible for modular screen media. Featuring replaceable polyurethane anchors, the new high open area modular deck is suitable for virtually any pin and sleeve modular screen media. The polyurethane anchors are easy to replace and prevent premature wear on the deck frame. Additionally, the open design of the modular deck prevents material build-up on the bar rails.

The F-Class can also be manufactured for side-tensioned or bottom deck end-tensioned screen media. Each new side-tensioned machine comes with Haver & Boecker Niagara’s signature Ty-Rail™ quick-tensioning system with the ability to cut screen change-out times in half.

The new F-Class continues to feature the hallmark performance the machine is known for in tough applications, such as scalping, wet and dry screening, dedusting and more. Supported by high-performance, double-spherical roller bearings, the machine’s double eccentric shaft assembly creates a constant stroke to maintain g-force during material surging, providing constant material stratification to ensure product specification. It also creates a dynamically balanced system that transmits virtually no vibration into the structure — or chassis — preserving the integrity of the structure while also allowing for multiple machine installations. Additionally, the double eccentric shaft assembly reduces blinding and pegging while improving overall screening efficiency.

The vibrating screen continues to be equipped with shear rubber mounts rather than springs. Shear rubber mounts minimize the lateral movement caused by traditional springs. This reduces noise, maintains smoother operation and extends the life of a vibrating screen.

The F-Class is available with a variety of configurations and upgrades, and can be used in both stationary and portable applications.

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.

Haver & Boecker Niagara Pulse Impact Test

Haver & Boecker Niagara’s new Impact Testing to its Pulse portfolio with experimental modal analysis. The impact test — also known as the hammer test or bump test — is now part of the company’s quality assurance program during factory testing as well as on-site.

This ensures each machine is properly tuned to avoid operating in resonance, ensuring efficient operation. With the opportunity to integrate impact testing data with other Pulse portfolio reporting and historical tracking, including Pulse Vibration Analysis and Pulse Condition Monitoring, Haver & Boecker Niagara can provide a more holistic view of the individual machine that helps customers maximize uptime through historical tracking.

Haver & Boecker Niagara’s suite of Pulse diagnostic tools help operations to monitor the health of vibrating screens for optimum screening performance and equipment durability.

“Increasing customer productivity and profits are at the heart of every Haver & Boecker Niagara innovation,” said Wilm Schulz, Haver & Boecker Niagara’s parts and service manager. “With advances in technology, we’re able to provide real-time information that helps customers make well-informed decisions about their machine. Including impact testing gives us one more data point to extend the life and maintain the health of a vibrating screen.”

Operating in resonance can diminish productivity, incur damage to vibrating screens and pose safety risks. Impact testing involves striking the machine at key points with a dead blow hammer while the machine is off. It typically includes the four corners but can be expanded to additional areas. Collected data is analyzed to identify the machine’s individual natural frequencies. Based on results, engineers can adjust machine parameters to avoid these frequencies during operation.

Integration into the Pulse software opens up opportunities for easier on-site impact testing. Natural frequency can shift over time as components are repaired or replaced, resulting in irregularities that could translate into diminished performance, decreased efficiency, increased operating costs and imminent breakdown. By incorporating impact testing into Haver & Boecker Niagara’s signature Pulse diagnostics tools, producers can ensure optimum screening performance and equipment reliability.

The service program includes a complete vibrating screen inspection by a Haver & Boecker Niagara certified service technician. Following the inspection, customers receive a Pulse Diagnostic Report, which provides an analysis of their vibrating screen and detailed recommendations to extend the lifespan of the machine and ensure its health. All Pulse Diagnostic Reports are stored in an online data management system, giving customers access to a complete record of their vibrating screen’s service and performance histories. This information allows customers to track changes in vibrating behaviour and predict future performance so that they may shift from reactive to predictive maintenance.

Impact testing, along with the other suite of Pulse services, is a critical part of PROcheck, Haver & Boecker Niagara’s comprehensive service process dedicated to keeping customers’ operations running at peak performance. PROcheck applies Haver & Boecker Niagara’s expertise during inspection of customers’ screening processes in order to recommend best practices for proficiency. It includes diagnostics, processing equipment, engineered screen media, original parts, rebuilds and upgrades, services, plants and process engineering.
