Circular milling of Raptor 1100 cone crusher seal landing, WA, Australia

Machining rectification on in-frame at Cloudbreak Mine (Minprovise, WA) was carried out with precision in one of the harshest environments in Australia with no stoppages or safety issues, saving the client significant down-time costs.

Transalign ISM were approached by Minprovise in W.A. to carry out a machining rectification on in-frame and on site at Cloudbreak Mine in the lower Pilbara region of W.A. The process required setting up of 2 metre circular milling machine over the 640 diameter main shaft and carrying out circular milling of the badly damaged seal landing seat to a depth of 32mm.

A 70mm wide pre-machined and shouldered insert was then shrunk into position and secured by drilling, tapping and installing M12 counter sunk head socket screws.  This process saved the client significant down-time costs which would have resulted by sending the frame away for repair in Perth.

In total the equipment was out of service for five days which included dis-assembly, machining, re-assembly and start-up.  The work was carried out with precision in one of the harsher environments in Australia with no stoppages or safety issues.
