USA-based Screen Machine Industries has a new patented design for its model CST track mounted portable cone crusher. This patent places a screen in front of the cone crushing chamber to remove the fines before crushing, prolonging the life of the cone and associated wear parts while maximising productivity.
The company said that while pre-screening the fines on a cone crusher is not unheard of, the open feed design placing the screen in front of the cone is unique.
It provides increased ease of maintenance on the screenbox, which is equipped with patented Smooth Start Technology. 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. This design feature is only available on the CST Cone crusher from Screen Machine Industries.
