View and share all available primary gyratory crusher upgrades

One size doesn't fit all and it doesn't have to. Why move from an MK I to II to III? Create your very own MK X. Mix and match gyratory crusher upgrades to suit your unique goals and desired investment levels.

nXt level Production
Primary gyratory crushers are the initial driving force for the entire mineral processing circuit. Adding extra production capacity here can have significant effects downstream. Over the years, Metso Outotec has introduced many advancements that bring increased speeds, higher installed power and mechanical improvements – all designed to provide you with next level production.
These features are all available in the Superior® MKIII – but you can also achieve those same benefits with your previous generation crusher through integrating one or all of our three production upgrade options. View them below.
1. Arched / Super Spider - Reduced bridging downtime
2. Speed Increase - More capacity
3. Mainshaft positioning sensor - Better protection

nXt level Reliability
If your first stage of crushing is not performing, it will have effects throughout all mineral processing stages. This makes reliability a key concern. Metso Outotec has developed five upgrade options that not only minimize wear but also help to ensure a long and productive life for your crusher and its key components. View them below.
1. Shimmed spider bushing - Reduced wear
2. Pinion bearings - Longer life
3. Large upper journal mainshaft & sleeve - Increased strength
4. Balance cylinders - Added flexibility
5. Offset eccentric gear - Longer wear life

nXt level Maintenance
As equipment ages, production efficiency and reliability can decline. Proper maintenance is key to reduce the signs of aging to ensure that your production goals are met. Maintenance can be a costly and labor-intensive job, which is why Metso Outotec has engineered six upgrades to simplify and speed up these tasks. View them below.
1. Exterior gear backlash adjustment - Simplified process
2. Pinion bearing & oil level sensors - Improved planning
3. Rotable top shell - Maximized uptime
4. Hydraulic shell separators - Faster removal with less manpower
5. Spider bushing auto lube - Consistent lubrication
6. Flow meter stations - Monitoring capabilities
