Screen Machine Awarded Patent

Etna, Ohio, February 15, 2016: Etna, OH – Screen Machine Industries LLC once again delivers American ingenuity with a new patented design for their model CST track mounted portable cone crusher. This patent places a screen in front of the cone crushing chamber to remove the fines prior to crushing, which dramatically prolongs the life of the cone and associated wear parts while maximizing productivity.

Pre-screening the fines on a cone crusher is not completely unheard of, however, the Screen Machine Industries open feed design placing the screen in front of the cone is unique. This provides increased ease of maintenance on the screenbox, which is equipped with patented Smooth Start Technology (U.S. Patent #6,669,026). Fine material that passes through the screen bypasses the cone to reduce unnecessary wear and increases rock-on-rock crushing for maximum efficiency. This screen also folds down for clearance from the cone, enabling easier servicing of the cone itself. U.S. Patent # 9,186,681 guarantees that this unique design feature is only available on the CST Cone crusher from Screen Machine Industries.
