FAQ — Minyu jaw crusher parts

How do Minyu MS jaw plates differ from other brands?

Minyu MS series uses a steeper crushing angle with higher compression ratios per stroke — good for throughput but plates wear slightly faster. Mn21Cr2 is recommended for abrasive feed.

What is the typical jaw plate life on Minyu crushers?

350–700 hours on medium-hard rock. Minyu's longer stroke means more material movement per cycle, which accelerates wear on the lower third of the jaw. Rotating plates at 50% wear extends total life 20–30%.

MS vs MSS — what's the difference for wear parts?

MS: standard primary jaw. MSS: super heavy-duty variant with thicker frame and larger bearings. Jaw plates are NOT interchangeable between MS and MSS — confirm your model before ordering.
