Bottom Shell Hub Liners for Gyratory Crushers
Bottom shell hub liners are the sacrificial wear lining that protects the bottom shell of a gyratory crusher from the impact and abrasion of ore falling through the crushing chamber. Monmet supplies replacement sets to your drawing or sketch, or reverse-engineered from a worn liner — cast or fabricated and formed to the curvature of your machine.
Quick answer
Bottom shell hub liners are replaceable wear plates bolted inside the bottom shell of a gyratory crusher. They absorb impact and abrasion so the crusher's structural shell is not damaged, and are replaced as a set when worn. Monmet supplies them from your drawing, sketch or a worn sample.
What the part does
The liners line the inside wall of the crusher's bottom shell, taking the impact and abrasive wear of raw ore falling through the chamber. Because they are consumables, they are replaced on a wear schedule so the structural shell itself is never worn or damaged — the whole point of fitting them.
How Monmet supplies them
Sets are produced through our worldwide network of foundries, forges and workshops. Depending on your drawing they are cast and heat treated, or cut from plate and rolled or pressed to the required curvature, then drilled and machined for the mounting hardware and fit-checked against the shell dimensions.
What Monmet needs to quote
Crusher size, a drawing, sketch or worn sample, the number of segments per set, the mounting hardware arrangement, and the grade and hardness required on your purchase order. If no drawing exists, we reverse-engineer the set from a worn or new sample.
