Cone Crusher Liners

Makuri provides real solutions for cone crusher liners that go above and beyond the usual OEM standard profiles, leading to measurable improvements and lowest TCO every time.

Secondary Crushers
Optimized secondary crushing improves overall plant throughput and reduces TCO.

Tertiary Crushers
Increasingly smaller feed material & smaller crushed product sizing requirements present a range of challenges.

Pebble Crushers
The hardest crushing duty on a mine site is often the pebble crushers. Mill pebbles are tougher than normal ROM feed and often contain wet sticky fines, mill balls and ball fragments. These cause a variety of operational and maintenance issues.

Secondary Crusher Typical Problems

Accordion
  • Blockages due to inability to handle slabby and/or large feed
  • Unable to maintain sufficient feed opening as liners wear
  • High power draw
  • Unable to achieve target gap setting
  • Unexpected liner failures
  • Uneven wear between bowl and mantle liners
  • Excessive wear at the bottom of the chamber
  • Cracking heads
  • Unplanned shutdowns to change mainframe liners and arm guards —life doesn’t match main liners

These issues will not be fixed by simply making thicker liners or changing material grades.

Tertiary Crushers Typical Problems

Accordion
  • Tramping due to excess fine material in the chamber
  • Unable to achieve the target gap within power limitations
  • Lost production rate towards end of liner life
  • Unusual wear behavior due to incorrect liner selection
  • Unable to achieve a choke-fed condition
  • These will not be resolved by simply making thicker liners or changing material grades

These issues will not be fixed by simply making thicker liners or changing material grades.

Typical Problems

Accordion
  • Unable to achieve and maintain target CSS over the full life of the liners
  • Poor availability due to planning based on unpredictable liner life, leading to overly conservative shutdown plans
  • Unplanned maintenance due to liner and machine failures
  • Poor utilization due to tramp metal detections and low bin levels
  • Excessive liner failures due to mill ball damage
  • Poor power utilization due to poor cavity profiles over full life of the liners
  • Often operating in a ring bounce / bowl flutter condition due to poor cavity profiles
  • Operators running machines at a gap setting tighter than the machine is able to handle
