A Very Unique Project for Marion Machine

This month’s project was a unique one, but certainly nothing our talented team at Marion machine couldn’t handle!

A customer sent in their 42” Fuller Gyratory Crusher and all the spare parts including the main shaft, and spider for a fleet reconditioning.

The catch? The shaft was stuck to the spider.

Galling, which is a tearing action caused by metal on metal movement, forced these pieces to knot up and fuse, creating a big problem for the customer!  Thankfully, Marion Machine was just a phone call away, and the customer reached out to us to put our unique pressing capabilities into action to get these parts separated.

This process is not always simple, and our experts here at Marion Machine decide on a case by case basis the best way to approach each job.

Here is how the process worked for this customer:

First, our team, including Keith Jackson, Steve McHone, and Robby Robinson, used our large press to press the shaft out of the spider and cut out the bushing to free it.  After the bushing was out, we repaired the bore to factory conditions, replaced the spider bushing, then sent both pieces back to the customer to be reinstalled at the site. Presto!  Problem solved, and this customer is back in action.

Pressing is not specific to gyratory crushers, but they are the largest, and here at Marion Machine we have the facilities, equipment and expertise required to fix big problems on big machines!  We have used our press capabilities to repair and machine a variety of crushing equipment including Symons and HP heads and shafts.  If you find yourself facing a problem with your crusher, find out how we can help by visiting our capabilities page or call us today at 1-800-627-1639.

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.
