The CST Cone Crusher is a large track-mounted portable crusher plant designed for secondary crushing of hard rock.
The CST Cone Crusher is a large track-mounted portable crusher plant designed for secondary crushing of hard rock.

A new patented design for Screen Machine’s CST track-mounted portable cone crusher features a screen in front of the cone crushing chamber to remove the fines prior to crushing. This dramatically prolongs the life of the cone and associated wear parts while maximizing productivity, the company says.

While pre-screening the fines on a cone crusher is not completely unheard of, the CST’s open feed design, which places 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. Fine material that passes through the screen bypasses the cone, reducing unnecessary wear and increasing rock-on-rock crushing for maximum efficiency. This screen also folds down for clearance from the cone, enabling easier servicing of the cone itself.
