PRESS RELEASE: The 1/2in (1.27cm)-thick polyurethane liner is installed on the cross beams of a vibrating screen to reduce the impact of passing material.
Haver & Boecker engineers designed Zip Guard to support equipment longevity and minimise downtime for maintenance. Installed by a certified Haver & Boecker technician, Zip Guard is available for all Tyler vibrating screens and offers easy access to the beam since it uses industrial-strength ties to attach the liner to the beam.
“Cross beams take the brunt of the impact in vibrating screens and most machines do not come standard with protective liners, which means they experience wear from day one,” said Markus Kopper, Haver & Boecker Rocky Mountains general manager.
Alternative protective methods use rubber, which adheres directly onto the cross beam. The glue removal process is time-consuming, resulting in increased downtime for repairs. Zip Guard’s polyurethane barrier not only lasts longer and experiences less wear, but inspecting the cross beams for deterioration or cracking is simpler than the glue alternative as the liners are simply installed using industrial-strength ties. Cross beams and liners should be inspected regularly and, when a customer notices wear, they can purchase a replacement and install Zip Guard to keep their machine up and running.
“In this industry, operations don’t have time for lengthy maintenance downtime,” said Kopper. “This dilemma led us to develop Zip Guard, to ensure customers’ machines can take the impact and run efficiently for longer intervals with minimal wear.”
Cross beams, side plates, feed boxes, discharge lips, bar rails and shaft housings are all structural components that provide rigidity in a vibrating screen. Over time regular wear sacrifices the engineered rigidity required for the longevity of the machine. To combat wear, Haver & Boecker carries a full line of Tyrethane bar rail liners to protect the entire screen deck and maximise the life of both the vibrating screen and the screen media. Customers can upgrade any new or existing Tyler vibrating screen with the protective liners.
