Time, technology and innovation have allowed inventors the opportunity to create machines that are more reliable, faster and have a greater output. Since 1917, Haver & Boecker has been streamlining the mining and aggregates process with the invention and evolution of their vibrating screens.
Haver & Boecker, formerly W.S. Tyler, invented the Ty-Rock, the first vibrating screen with four-bearing technology, in 1935. Years of innovation perfected this machine into what is known today as the Tyler F-Class.
Even after 70 years of operation, the classic F-Class design still remains an important part of an aggregates operation. The Waterford Group’s machine has been running since 1943, with a few updates, including new paint and added spray bars. Brandon Smith, Waterford Group site supervisor, explained that it’s one of the best-running machines on the site.
The four-bearing design of the F-Class minimizes structural vibration, allowing for multiple machine installations within the same structure. Delivering a consistent stroke that two-bearing screens cannot provide, the four-bearing screen virtually eliminates blinding and pegging. Plus it allows for a continual circular screening action, which produces a constant, optimized g-force.
With its always-evolving technology, the F-Class takes on some of the toughest jobs — from scalping to classifying ores, minerals, stones and gravel.
In more recent history, Haver & Boecker saw the need for portability in the aggregates industry and decided to take its landmark machine on the road. The portable F-Class features a base frame that attaches to a custom-built chassis. The trailer’s hydraulic system quickly positions the vibrating screen at the optimal angle and, in just 20 minutes, can be taken down and moved to the next site.
In 2016, Haver & Boecker debuted the split-bucket mounting system for the F-Class. Engineers designed the system to give technicians and operators easy access to critical components, speeding maintenance and reducing downtime. A two-piece body bracket allows operators to remove the side arm and bucket in one piece. Prior to this innovation, technicians had to disconnect the rubber mounts and unscrew 15 bolts.
Throughout the past eight decades, F-Class innovations have optimized screening performance for mining and aggregates operations around the world by increasing production, creating portability and minimizing downtime.
