Repairing of the spider tapered internal bore - 60" x 89" -Primatry Gyratory Crusher (1 reply and 1 comment)
Please join and login to participate and leave a comment.
Dear Friends,
I working on a solution for repairing the spider tapered internal bore of our 60” x 89” primary gyratory crusher , as it has loosed its fit interference due excessive wear and can not hold the spider bushing. The results are frequently broken bolts and long shutdown of the crusher.
Many companies have proposed to weld and machine the tapered internal bore in place without the needs of transporting of the spider for a workshop.
My experience shows that the best and more accuracy procedure is to machine it in a vertical lathe as we need to reach very tight dimensional and geometric tolerances.
What are your opinions? Have any of you had this kind of experience?
Regards,
