Superior primary gyratory crusher upgrades for increased production
Increased Production

Primary gyratory crushers are the initial driving force for the mineral processing circuit. Adding extra production capacity can have significant effects downstream. Metso has introduced advancements that bring increased speeds, higher installed power and mechanical improvements – all designed to bring your production to the next level.

The features are 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.

Production upgrades mean:

  • optimizing haulage plans
  • providing the most efficient energy consumption
  • reducing down/idle time
  • a more sustainable operation

Arched Spider / Super Spider upgrade for Metso Superior Primary Gyratory  Crusher
Arched / super spider


The Arched Spider geometry changes the available feed opening for better flow of material into the crushing chamber, reducing bridging and increasing productivity. The Super Spider builds further on these improvements by increasing the feed opening.

Mainshaft positioning sensor upgrade for Metso Superior Primary Gyratory  Crusher
Mainshaft positioning sensor


The mainshaft positioning sensor (MPS) probe enables operators to monitor and adjust mainshaft position to compensate for wear parts quickly and efficiently. Data of mainshaft position can be used to determine wear rates along with providing feedback if mainshaft position is dangerously high or low in its operating range.


Superior primary gyratory crusher upgrades for increased reliability
Better 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 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 while reducing the volume of parts and minimizing waste. Less waste and parts needed mean a more holistic and sustainable operation.

Shimmed spider bushing upgrade for Metso Superior Primary Gyratory  Crusher
Shimmed spider bushing


The shimmed spider bushing comes standard with more robust metallurgy to stave off wear that can be detrimental to components throughout the crusher. A key feature to the bushing is its shimable design that compensates for wear to the spider bushing bore. This allows for long term operation and planning for future repairs once all shims are removed.


Pinion bearings upgrade for Metso Superior Primary Gyratory  Crusher
Pinion bearings


The re-designed pinion bearings are capable of higher load handling as well as increased operating speed. This upgrade brings benefit alone, however it becomes more critical if you are considering a speed or production upgrade in the future.


Large upper journal mainshaft and sleeve upgrade for Metso Superior Primary Gyratory  Crusher
Large upper journal mainshaft & sleeve


Through design changes, the crusher mainshaft has undergone numerous updates in geometry and manufacturing methods. This combination of changes have increased the strength of the mainshaft by up to 70%. Increased strength improves long term reliability of your machine for current operation and future production increases.


Balance cylinders upgrade for Metso Superior Primary Gyratory  Crusher
Balance cylinders


Over the life of a mine, changes to operation or ore characteristics can lead to the need for increased balance cylinder capacity. Proper balance cylinder capacity keeps internal crusher components in proper alignment during tough crushing events. This allows your machine to continue operating at peak efficiency for reliable long term operation.


Offset eccentric gear upgrade for Metso Superior Primary Gyratory  Crusher
Offset eccentric gear


The offset eccentric gear allows for better gear to pinion contact, which in turn distributes the load across the complete tooth. This provides for longer wear life and better power distribution.


Superior primary gyratory crusher upgrades for improved maintenance
Improved 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 has engineered six upgrades to simplify and speed up these tasks.

Maintenance upgrades can help lower downtime and require less man-hours needed to perform operations necessary to keep equipment performing at peak level. More uptime means a more efficient and sustainable operation.

Exterior gear backlash adjustment upgrade for Metso Superior Primary Gyratory  Crusher
Exterior gear backlash adjustment


This upgrade allows for quicker maintenance thanks to the ability to now adjust the gearing backlash outside of the crusher. The result is a simplified, faster, and safer process for all involved.


Pinion bearing and oil level sensors upgrade for Metso Superior Primary Gyratory  Crusher
Pinion bearing & oil level sensors


With sensors built-in, you now have the capability to monitor the pinion shaft assembly. This increased visibility allows for better maintenance planning as you can now get ahead of potential issues.

Rotable top shell

Maximized uptime

This solution saves time as you do not need to install concaves during shutdown. Fewer components are being lifted during the outage period, allowing for maintenance to be done in a more controlled and safe environment. During the shutdown, the shells are separated (optionally with hydraulic shell separators), lifted, and replaced with the relined shells. Learn more about Rotable Top Shell


Hydraulic shell separators upgrade for Metso Superior Primary Gyratory  Crusher
Hydraulic shell separators


These easy to install kits allow for faster and safer separation of spider and top shells minimizing needed maintenance manpower during component removal. Hydraulic jacking components are used at each shell separation reducing the downtime for their removal.


Spider bushing auto lube upgrade for Metso Superior Primary Gyratory  Crusher
Spider bushing auto lube


Improvements to spider lubrication systems have provided a more maintenance friendly alternative to previous generations. New systems have integrated lubrication level sensing into the spider cavity providing feedback to automatically replenish oil to the spider cavity as needed. Built-in alarms to the system will alert maintenance personnel to potential issues.


Flow meter stations upgrade for Metso Superior Primary Gyratory  Crusher
Flow meter stations


Flow meter stations on your primary gyratory provide insight into the health of the lubrication system and assures monitoring of lubrication flow into the machine.
