Mineral Processing Industry

If you operate a plant in the Mineral Processing industries, you’ll be familiar with the challenge of maintaining production targets while working within ever-tighter operating budgets for the upgrading and maintenance of equipment that will enable your company to stay competitive in demanding markets.

Maintenance, Modification and Equipment Repairs

The global Metalock Engineering Group have all been involved in the Mining and Quarrying, Cement and Aggregates industries for decades and our skills and experience have provided an around-the-clock, around-the-globe, lifeline to the processing industry for over 70 years.

We carry out repairs on large items of plant and machinery in open cast mining, quarrying, cement plants, and crushing plants.

Bespoke Solutions Save You Money

When we tackled the in situ recovery of a 915mm diameter x 915 mm long cement mill bearing journal,  our orbital machining technology salvaged the shaft diameter at a fraction of the cost of conventional shaft replacement. Ingenuity and innovation underpin our position as a leader in specialist engineering services for the process industries.

When Lafarge Cement challenged us to machine a 5.2m diameter rotary base table, we designed an extra special machining rig to get the job done.

It’s examples like these that endear us to demanding customers around the world.

Typical Repairs We Undertake in These Industries:

• Metalock Cold Casting Repairs on cracked or broken castings in Cast Iron or Cast Steel.
• Re-grinding Kiln Tyre and Support Rollers.
• Re-machining on Rotary Tables.
• Shaft Diameter Recovery using our orbital machining/grinding on a variety of shaft journals on Primary and Cone Crushers, Ball Mills, and Drives.
• Machinery Bedplate Milling (flat and level).
• Gearbox In-line Boring.
• Flange Machining (all sizes) - including Slew Ring location faces
• Girth Wheel and Crusher Gear tooth replacement.
• Welding Repairs to kiln Tyres, Support Rollers, and associated Plant.
