Haver & Boecker Niagara Launches Niagara F-Class Vibrating Screen
Haver & Boecker Niagara, St. Catherines, Ontario, launched the next generation Niagara F-Class vibrating screen at MINExpo 2021 in Las Vegas. The vibrating screen is now primarily manufactured with vibration-resistant lockbolts instead of the traditional welding used in previous designs. Bar rails are now fastened to the cross beams with lockbolts. The new 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, according to the manufacturer.
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, according to the manufacturer. Additionally, the open design of the modular deck prevents material buildup 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 Ty-Rail™ quick-tensioning system with the ability to cut screen change-out times in half.
Supported by 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. It also creates a dynamically balanced system that transmits virtually no vibration into the structure—or chassis—preserving the integrity of the structure while allowing for multiple machine installations.
