Spares
Spares
Apart from supporting all our own new mill installations with the best spares and aftermarket support, NCP International also provides support and spares to mills of any brand.
Girth Gears
NCP International has the capability to supply new girth gears up to 16m Ø, 1500mm face width. If no drawings exist, we will re-engineer your existing gear and deliver an identical new girth gear to your site.
We pride ourselves on optimizing delivery time on new girth gears and can offer delivery from 20-46 weeks depending on the gear size.
Pinions and Pinion Shaft Assemblies
NCP International supplies pinion gears or complete pinion shaft assemblies. These gears are supplied as case-carburized or through-hardened with an AGMA 9 to 12 surface finish as per the client’s requirements. On-site measurement will verify dimensions to ensure that the gears supplied are fit for purpose.
NCP International also offers in-house gear design services should the client consider changing the existing mill’s application, operating speeds, loading or installed power.
Main Trunnion Bearing Spares
NCP International offers new lead-bronze bearing inserts, roller bearings or other bearing spares as required. We also assist with on-site bearing inspections and wear item replacement (eg. seals, strainers, etc). Our leaded bronze inserts are of the highest spun-cast quality with quickest delivery timing.
Mill Wear Liners
We supply competitively priced new mill liners, as well as new Chromoly and Hi-chrome wear lining systems. Our teams can install supplied liners as per the clients prerogative. We also incorporate a design office that offers DEM and charged Trajectory Analysis. In this way, we optimize existing liner designs and improve your grinding efficiency.
Shell
NCP International offers new mill shells where required. Imported or local manufacture of shells, heads and girth gears can be expedited to ensure that delivery times are kept to a minimum. Quick change-out of mill shells is also offered
Lube System Upgrades
Poor lubrication from outdated, originally-supplied lubrication systems is the leading cause of bearing failure on mills. NCP International offers design reviews of existing lubrication systems installed at your plant. We offer new, optimized and proven lubrication systems which will increase your mill’s availability and annual production. Systems offered include main trunnion bearing lube systems, gearbox and pinion bearing lube systems as well as gear spray grease lube systems.
Gearboxes
In addition to supplying spare gearboxes for our new mill supply, NCP International also supplies new spare gearboxes to match the dimensions and constraints of any existing mill installation (of any make).
We have excellent working relationships with many OEM brands and offer excellent delivery times with an engineered solution to minimize client risk.
Motors
New motors matching your existing site dimensional constraints can be supplied as operating units or as critical spares. All motor FAT’s are witnessed by our experienced site / design personnel and signed off prior to dispatch.
Heads
Spare mill heads can be newly manufactured or refurbished/re-engineered from existing heads to fit your installation.
NCP International offers market-leading turn around times.
Instrumentation Upgrades
NCP International offers a technical review of your current mill protection levels and recommendations on instrumentation and control philosophy upgrades. Please request that an engineer visit your plant to assess your current mill installation.
