Haver & Boecker Niagara Highlights Advantages of Pairing Eccentric Screening Tech with Polyurethane Screen Media
Haver & Boecker Niagara, St. Catharines, Ontario, highlights the advantages of pairing eccentric screening technology with polyurethane screen media. The combination of the eccentric machines in its Niagara F-Class and Niagara N-Class with polyurethane media, such as Ty-Max and Ty-Deck, are designed to offer more uptime, fewer screening problems and higher screening efficiency. Here’s what they’ve learned:
“We pride ourselves on providing our customers technology that advances their operations’ productivity and profitability,” said Karen Thompson, president of Haver & Boecker Niagara’s North American and Australian operations. “Though each of these two technologies are highly beneficial on their own, their benefits dramatically increase when combined. The result for our customers is less downtime and better screening.”
Advanced eccentric screening technology implemented by Haver & Boecker Niagara, combined with the benefits of the manufacturer’s polyurethane media has been shown to reduce pegging and blinding; handle high impacts; improve screening action and increase screening efficiency; and lessen vibrations transmitted to the structure.
Eccentric screening optimizes vibrating screens for handling heavy-duty applications, such as classifying and scalping. The eccentric shaft design forces the screen body to follow the shaft movement. While it travels upward, the counterbalance weights move in the opposite direction and create an equal force to that generated by the body. As a result, the forces cancel each other out while generating a consistent positive stroke that minimizes structural vibration and handles material volume spikes without losing momentum.
This leads to the machine transmitting fewer vibrations to the structure and allows for longer component life. Additionally, the design creates a self-cleaning action that reduces blinding and pegging while improving overall screening efficiency.
Haver & Boecker Niagara’s polyurethane media then offers a combination of open area and wear life for both wet and dry applications. It is poured open cast, resulting in 1.5 to 2 times longer wear life than injection-molded products sold at comparable prices, according to the manufacturer. In addition, open cast polyurethane permanently hardens when cured to maintain its chemical properties to improve wear life.
Operations can choose wear liners for improved screen media protection and even higher performance and longevity from their machines. Liners for vibrating screen cross beams are also available.
