Wear parts
Roll Surfaces, Studs, Side Plates and Chute Wear Systems
The roll centre, edges, side plates and feed/discharge passages have different wear mechanisms. The cards link part location and material choices to component pages; final confirmation follows the PM model and drawings.

Frequently asked questions
How is an FLS HPGR model identified?
First check PM model and machine size, then roll diameter, width, serial number, surface type, fixed/floating roll position and Standard / Pro configuration.
Can HPGR Standard use Pro parts?
FLS states that machine sizes 4–10 can receive Pro upgrades. Each modification and part still requires checks against size, serial number, upgrade scope and modification drawings.
Can third-party roll-surface or stud references be checked?
Yes. Submit the reference, PM model, roll diameter and width, location, surface layout, used-part photographs and material data to establish a match.
