American Made at Marion Machine


This month at Marion Machine, we are showing our patriotic colors…literally!

This 54×75 Gyratory rock crusher came to us in need of some TLC including inspection and repair of the bottom shell, top shell, and spider.  Marion Machine is known for our ability to repair large equipment and this job was no exception!  Because of the size of this job, this repair took over 15,000 pounds of weld wire to repair! The first step in the process was to thoroughly inspect the bottom shell.  We then welded the five degree taper, dust collar area, main bushing bore, keyway, pinion shaft housing bores, wear and wash out areas, and the hydraset area.  We then stress relieved with our in-house oven before machining all welded features and drilling and tapping new holes.  We installed four new bolt down plates and then ground, coated, and painted it red.

On to the top shell!

For the top shell, we followed the same inspection process and then welded both five degree tapers (one on the top and one on the bottom), spider flange face, and bottom shell flange face.  We then built up the concave ribs, removed and repaired all cracks, stress relieved and then machined it all to factory specifications.  The final step for the top shell was painting it white.

Finally, the spider is up for inspection.

Our expert team welded the five degree taper, dust collar fit, main bushing bore, bushing holes, dome fit, and wear wash out areas.  We then replaced the bars on the outside diameter of the bushing bore, stress relieved it and machined it back to factory specs.  Now that all the repairs are complete, it’s time to paint it blue to complete our patriotic paint job!

Made and machined in America, this 54×75 Gyratory crusher is repaired and ready to make America proud!

Our Metso HP 800 Mainframe had a loose shaft and we re-fit the shaft back to OEM specs with a 2-week-turnaround to get a 3.5-million-ton-plant back up and running.
