Mining, quarry and mineral processing onsite metalock repairs
A no-compromise engineering environment…
The mining industries equipment has to deal with particularly harsh operating conditions. This takes it toll on the equipment and operators, the resulting metal fatigue could result in fracture or breakage of the parent metal.
A characteristic of this industry is that any stoppages cannot be tolerated, due to the high cost of loss of production. It is with this in mind that MIA members are skilled in the use of the onsite Metalock process to repair mining equipment. Repairs are challenging in the mining industry, due to the nature of the working conditions and the size and design of the plant, but this is not the case for Metalock.
The Metalock onsite process allows for the immediate diagnosis of the damage, where many of the repairs can be carried out with little or no dismantling. Where the downtime is expected to be weeks, a Metalock repair can bring operations be back in hours or days, especially when using other members technicians to speed up the repair.
In addition to speed of repair, in many instances equipment can be repaired in stages to allow for production to continue during the repair procedure.
Our members have been working in mining engineering maintenance for decades, and have built up solid relationships with customers based on our excellent turn-around capabilities and understanding the needs of the customer.
Some of the repairs our members carry out include:
ball mills & drives,
machinery bedplates & frames,
girth wheel & crusher gear tooth replacement,
Case study – Alcoa Rod Mill bearing journal, 6 day repair
Rod Mill No 9, Discharge end / bearing Journal. Fracture measured some 800mm and was growing rapidly. Oil loss was up to 300Litres daily. Metalock of Australia P/L repaired unit with 3 Masterlocks in high tensile material together with 16 sets of No. 5 L Metalocks.
Preparations took a few days – repairs on site 6 days with 3 crew. Repairs included cracktest, plating / sealing area prior to repairs and hand finishing on journal. Rod mill went back into affect almost immediately after repairs – no fluid loss – Alcoa’s engineers very happy with repair and time-frame being maintained. – Metalock member, Australia
