SCREWS when used in abrasive or corrosive media, are exposed to wear and need often to be replaced at great expense.
Especially conical SCREW SHAFTS are high-priced spare parts and are prone to totally fail under heavy wear. For a small investment cost, the lifetime can be greatly prolonged thanks to the wear protection INFINITE SHIELD.
The wear requires the regular exchange of various plant parts. The investment pays for itself in INFINITE SHIELD after a short time.
