Q: What is the expected service life of the high-chromium alloy roller skins?

Hydraulic Double Roller Crusher

HSM uses High-Chromium Manganese Steel Alloy for all roller skins. Depending on the abrasiveness of your material (such as quartz vs. limestone), these rollers typically last 3 to 5 times longer than standard carbon steel variants. Our modular “split-skin” design also allows for quick onsite replacement without dismantling the entire main shaft, saving up to 60% in labor time.
