What Is The Difference Between Active Planetary and Passive Planetary Concrete Grinders?
The main difference between active and passive planetary concrete grinders is the speed at which the tooling discs run. In an active planetary grinder, the tooling discs run at a much faster speed than the main tooling disk. This makes the active planetary grinder more aggressive and better for polishing. Here are some other differences between planetary and rotary concrete grinders:
Weight:
Rotary grinders are heavier than planetary grinders.
Mobility:
Planetary grinders are more mobile and can be modular. Rotary grinders are not designed for mobility.
Job Size:
Planetary grinders are better for smaller jobs, while rotary grinders are better for larger jobs.
Floor Coatings:
Planetary grinders are less effective at grinding thicker coatings.
Training:
Rotary grinders may require more training to use.
Movement:
Planetary grinders use belts and pulleys to move the discs. Rotary grinders utilize geared construction.
What Is A “Passive Planetary” Concrete Grinder?
The “Passive Planetary” Concrete Grinder is the model that is more focused on concrete grinding than concrete polishing. The passive planetary concrete grinder has three satellite discs that are not driven, they float. You can easily swap the satellite discs to turbo plugs instead of satellite discs with very little downtime.
What Is An “Active Planetary” Concrete Grinder?
The “Active Planetary” Concrete Grinder is the model that is more focused on concrete polishing than concrete grinding. The active planetary concrete grinder has three satellite discs that are driven in addition to the main disc. You can swap the satellite discs out to turbo plugs but it is not a quick change procedure like on the passive planetary model.
This is a more complicated system hence why they cost a little bit extra, but it does have a better cutting action when it comes to concrete polishing. Planetary Grinders work best on less aggressive jobs, such as polishing a concrete floor, light floor preparation, wood floor sanding instead of concrete grinding, ETC.
